As a firefighter I highly recommend keeping a CO2 extinguisher located outside your charging area. A standard ABC will work but should a fire occur the CO2 extinguisher wont produce the mess involved with an ABC. Also if you charge in a room. Definitely have that charge box. Been to quite a few fires recently involving battery abuse.
Right on, I just retired after 23yrs on the job, when I got into the hobby 6yrs ago I was a little cocky about the safety, thinking I've seen battery fires before. Had a cheap ass charger and did almost zero research into charging a lipo pack. Was using a lipo bag, but was renovating basement, and my abc and CO2 extinguishers were not in normal place. My first quad was a pre-built racer from a guy online, was common back then to use balance lead to power vtx. So I was charging 4s 1300mah, no balance lead, wrong setting, and bam it went from thermal run away to working fire in like 20sec. Melted lipo safety bag like it was a plastic gas station bag. Drywall started to ignite 3ft away, no flame impingement, straight radiant heat. Dumped 2 lrg glassed of water on it while gf tried to find extinguishers I moved. finally found the ABC one, which was a nice 10lb-er I thought would be plenty, it barely put it out..lol. I've told that story to many people getting into the hobby, they are no joke.
I meant to say this originally, but went off topic...Was so pissed at myself I went the other way on safety, I built a lipo bunker box with a self extinguishing feature using AFFF. Well, not the real stuff, but it's cheap to make, baking soda with a splash of Potassium Sorbate mixed, and tossed in the bottom of an old mammo box. Then I rigged a system on the peg board above it, using Folgers coffee can with some white vinegar and splash of dish soap in it, tied to fishing string going down into the ammo box. Fire breaks fishing line, dumps can of vinegar n soap on baking soda lined in bottom of box, poof, you got AFFF knock off, foam. I'm working on making a video on how it works, I'll post here when finished.
I always get a Sharpie and write numbers on my batteries. That way I can effectively rotate them so they all get equal use. I can also keep track of a certain battery if it's not performing on par with the rest of them. Thanks for another informative video!
Yes I do the same and figure most people also number and date their batteries when new too. What I found is important is to always use/charge them in order...1,2,3,4,5,6,7, etc. which creates a pattern and makes a weak battery stand out as well as keeping track of their charge states by memory without guessing. I used to keep a log but found doing that provides enough information to maintain and monitor them. I call it a rule now after doing so exposed a bad charger port on a 4 port multi-charger. Thought it was a bad battery at first.
if you had a better charger you would be able to see the IR of them and you wouldn't need to wonder what is going on with the battery. no need to date them etc.
@@blue03r6 My chargers are quite good actually. But I like numbering identical batteries so they all get equal use. Nothing wrong with knowing how old a battery is either.
@@plasticapple704 but are you actually keeping track of how many cycles they have? Knowing their internal resistance is what you need to know. Also knowing which cells are out of balance. If you don't have a charger that shows you the IR and is capable of balance charging to veey close MV it doesn't matter how much you keep track of things or rotate. That's honestly a waste of time as it doesn't do anything. A good charger such as a icharger 308duo you can actually track all of that with their charging software. But seeing the IR is what you need to see. The more use the higher it goes. And cheap batteries like turnigy come with out of matched cells. The pack is only as good as the worst cell.
The videos of fires REALLY drive your points home. I am relatively new to drones and I did not know ALL of this stuff until now. In the beginning I was leaving my 2s batteries fully charged for months until i learned about leaving them at 50%. Only one swelled, maybe 1-2mm on each side.(it was safely disposed of) Now, I have a very nice battery charger with lots of diagnostics (Which I need to master). This vid showed me I still have a lot to learn.
Many areas now have "Do Not..." and "Must Recycle..." ordinances in place which prohibit disposal of these in household trash. Check with your local authorities. See section 13.1 of this safety data sheet: www.batteriesplus.com/image/sds-Venom-LithiumPolymer.pdf. Lithium batteries are neither specifically listed nor exempted from the Federal Environmental Protection Agency (US EPA) hazardous waste regulations, however they do encourage education with local municipalities involvement: www.epa.gov/sites/production/files/2018-03/documents/timpane_epa_li_slides312_ll_1.pdf
Good point. This will become more and more of an issue as lipos are used so widely and they are getting old. Few cities have the facilities to make disposal accessible.
@@RCReviewChannel Yes that's true unfortunately and it's a sign of wishful thinking just like the nuclear waste accumulating. Plutonium-239 (half-life 24,000 years), Technetium-99 (half-life 220,000 years), Iodine-129 (half-life 15.7 million years). Let's just hope technology can catch up and overtake Einstein's warnings and prove he was wrong about the outcome of human nature... (e{a})/t=E.
So true! Might just be us here in Scandinavia, but we've been recycling batteries since at least the 80s and every hardware and electronics store, gas station and most grocery stores have recycling bins. If I see anyone throw batteries in the trash I'm like "You fucking monster!"
GREAT compiling of valuable information!!! ALL good. 👍👍 The only one I have difficulty with (and it's NOT YOU, it's my situation), I CAN'T afford a bunch of Batteries like seemingly everyone else in the Hobby... I've got ONE 3S for my FlySky Radios (one between ALL of them), ONE 3S for my Aircraft and a 3S and 2S for my Crawlers. And those took a long time to acquire! 😖😞 I may be one of the last People to start using Lipos - because I've READ the information and SAW the Videos. I WAITED until I could save up for a GOOD Lipo/LiFe balance Charger!!! It conditions, inspects, balances, REJECTS charging BAD Batteries... And will set a Safe, Storage Charge! 👍👍 In a Hobby where I can no longer afford SQUAT, I sure don't want to LOSE what little I have... Carmine ✈🚂🚙
As usual,great advice. I for one din't understand the dangers of LiPo's when i 1st got into our great RC hobby untill i had a 1S rip on me when removing it from a drone, plug came off and wires crossed !! luckily it was a 300Mah but boy did it go off like a firework. Lesson learned. 👍🛩🚗
You spoke about topics no one really spoke to me about on various discord voice chats, this info is very much appreciated. I'll feel safer at home with what I have learned today.
Thanks for the info this is great. I’m just getting back into RC since I was a kid because my kids wanna do it and this is all new to me. Bought a fire bag before I even took the truck out of the box. Now I need a better charger. Thanks for the info.
I have a light on a xt60 that I use to get the last of the charge out after it’s too low to run. I try to fully discharge. #1 reason is my house burnt down because of a battery fire. Thanks for the video, I learned some new stuff.
You're discharging your cells down to zero after a run, and then using them AGAIN?? THAT is a HUGE NO-NO for lipo batteries! If you discharge them down to zero, and then attempt to charge and use them again after that, they CAN become very unstable and self-ignite at ANY point during the very next charging cycle, OR just randomly at ANY time while charged. It's VERY dangerous to fully discharge lithium cells, and then attempt to use them again. 💥 🔥
Good info! One question though. I have three different chargers, EV Peak QC3, Traxxas EZ Peak Live Dual and ISDT T8, and none of them charge to the same voltage. They don't even balance the same. What on charger says is balanced another charger can say is off by 0.1v or more. If lipos are so sensitive why aren't the chargers more equal?
So it's all about the quality of voltage electronics on your chargers. I would trust the best brand or most expensive as the reference. Ourp Protek 680 and Hobbymate Duo read exactly the same, to .01 volts. So the lipos are not really that critical in terms of peak voltage. 4.2 volts per cell is the limit and they all shut off around there.... 4.19, 4.21, 4.25, etc. In a test by friends to blow up lipos, they started getting puffy at 4.5 volts. And the really hissing, fire started at 4.8-4.9 volts. So that is pretty far up there.
I purchased the bar safe box from the description box. I just got my first 6S vehicle and I was watching videos on how much more serious of a battery it is compared to a 2,3 and 4s battery and I figured I’d touch on this video again and just purchased the box
Hi, thank you for the video. You explain things in a way a noob like me can easily understand. I really appreciate that. One additional question: If a fire occurs, what is the best way to try and put it out? Is there a specific type of fire extinguisher to keep on hand? I believe that for grease fires in the kitchen you should never use water as it will only cause the fire to spread, that one should instead attempt to smother the flames using a large thick towel, and or cover the area with baking soda. Thanks again!
They're batteries...it'll ironically result in a _C͟h͟e͟m͟i͟c͟a͟l͟ f͟i͟r͟e͟._ So you would use a Sodium bicarbonate extinguisher; aka class A B; AKAA just a normal extinguisher nothing crazy like buying something expensive & going on TH-cam for the manual that explains all this already. I'm no fireman, but Instead of asking a busy man a silly question that I could google on my own, I just come here Instead to educate you & help alleviate headaches from those who ask silly questions.
Thanks my friend for the great information and safety tips. I wasn't aware of the dangers. But I never charge my batteries unattended and gave great battery appropriate charges. Before watching this video I was going to parallel connect two 72 volt lithium batteries for longer range. One is 35 ah and the other one is 17.5. Combined 52.5 amp hour. Whit my components I would of gotten 150 kms. Give or take,depending on riding style,top speed, rider weight road grade(incline.decline).wind ,tire pressure,and outside temperature . I am not doing that cause it something. If bad happens,there go both of my batteries and they are very expensive. Thanks for the great advice. You mat have saved me alot of unnessscary problems.
Great Video!! I'm just getting into flying FPV and my biggest concern is with these Lipo Batteries. Wow!! Just seems like so many things can go wrong....Excellent video...I'm trying to learn as much as I can before I even try to charge one of these things. Must admit...they make me very nervous. Hope this video gets a ton of views!! Again..nicely done.
Bought batteries with a much too low C-rating once (my first fpv drone). The battery lost power extremely fast, performance became unreliable and all of the sudden the battery was at 2,6V/cell and super hot and puffy. Good thing it was a cold and dry winter so little to no risk of fire spreading. Speaking of which, is there any way of predicting how much power a model will suck down or is it trial and error? These days I err on the side of caution and pretty much always buy C-ratings of 75+ if possible.
Nice comprehensive video on Lipo maintenance. Use a Lipo killer to discharge the battery to 0v before disposal. Most Chargers will only discharge to minimum cell voltage. Thanks.
I always put my swollen lipo batterys in salt water, i leave battery for around 3 to 4 days in a bucket to discharge, do not remove once you have placed in salt wateter until 4 days, ihave done this for over twenty years, and disposed of hundreds, thankfully we have great C ratings on batterys today stoping stress on cells giving longer lipo life, discharging a swollen battery with discharge charger is good but i have seen them get agitated and burn up, get an extension lead and discharge in the middle of a open space outside, stay away if you see fire as the gases are strong and temperature can reach 600C, let it burn out no water, i was told over twenty years ago to put them into 20% sea salt to 70% cold water, this information was from a battery manufacturer, the batterys will turn to paper type slug in 4 days making it safe to dispose of in recycling, do this in a open space and away from pets and children and me ;) Stay safe guys and have fun with your toys, don't store lipo batterys in your home, ive come close to house fire in my early days of model flying large aircraft.
I've heard that immersing in salt water is not a good idea. The terminals can corrode before the charge is all gone from the plates of the cells. So I connect my old batteries to some 12v car bulbs and leave them until the bulbs no longer glow - then I put them in salt water for another couple of days.
@@stedenvideos3825 i agree, but ive never had a problem with using salt and water over many years with using 2s-3s-4s-5s-6s, draining with a bulb could put strain on the battery depending on what type of wattage bulb you use-and the voltage of battery, draining with low wattage would be good to trickle discharg and then salt water as you mentioned.
I just won't recommand that because in case of any cell is a little damaged then you will put lithium in your water, water that you will empty in your sink or toilets what is absolutly terrible for nature. Just fully discharge by connecting to your battery anything that uses curant such as a light bulb for exemple until is is completly empty, now you can also find some lipo-killers in your hobby store.
Been in rc since the early 80s seen the batteries change ,actually raced not just play and seen a many of battery disasters, manly as you say not knowing and stretching the poor battery, and your most definitely right as about chargers ,many times took the ole battery apart moved cells around so they wouldn't mess up ,so many out there no nothing about this ,now we got balance build in the charger ,if they use it
I love your videos thank you very much! They are very informative and helpful. Especially since I'm new to the "New RC world" I'm 43yrs old and the last RC I owned was a Traxxas Hawk 2. So yesterday I purchased the Blue Redcat Gen 8 after numerous videos of reviews/upgrading ect.. ect.. But again thank you for taking the time to explain the very important information we all need to know. Have a great day and stay safe
Buy a Venom Pro Quad or Venom Pro Duo and call it a day. Unless you just use Traxxas Lipos and in that case get the Traxxas Ez Peak Dual. I've got the Venom Pro Duo, The Ez Peak Dual, and an Ez Peak single and I've never had any problems and all the Ez Peaks are Beginner friendly the Venom Pro Duo and Quad you need a little more knowledge but it's not rocket science.
I am just getting used to the Lipo Batteries I used to be a nickel Metal hydride guy and I just got used with them. I ran NiCad batteries back in the day when you had to drain them to completely empty and recharge them ,and you only got five minutes out of a race, because a 4 minute race meant you had to use that battery in 4minutes 30 seconds to get the most out gear ratios and specialty brushed motors to win a race. I have a bunch of drills and everything that I use until they're dead and have a backup for them but I currently only running One battery with my trx4 blazer it's a 3-cell 4000 will it hurt it when I come back from a half an hour or 45 minute cruise to the woods to balance the battery on the charger? Until the next time I take it out a couple days later?
Excellent presentation. I subscribed for obvious reasons. Like not being a fan of burning down my house due to being ignorant of LiPO battery characteristics. Thanks for your presentation and warnings.
Another very nice thing about having 2 or more battery packs is that you'll be easily able to tell if something is going wrong with one of them. If one of the packs is suddenly losing punch or runtime, it's much easier to have another pack to compare it to. Using just one all the time, you may not notice the abnormal degradation if you don't have another one to compare it to.
For storage I have a lipo bag but wanted to know which area would be better for storage. A outside shaded shed with temperature fluctuations because of outside Temps with seasons or inside home with steady ambient Temps. I'm hesitant with indoor inside home. I have no garage only a tuff shed like the ones from home depot. Like a little house style.
Hi,I have some doubts why is there a continuous spark when I try to connect my lipo battery (2200 mah 11.1 volt 3s 30c) to my esc (30a) and is it because of friction Second thing the battery i mentioned above also showed the voltage in negative when I checked is with my multimeter.
I don’t use lipo’s for rc’s but I do use them with my Airsoft guns and this information is still very useful thanks. I understand that you can never be too safe but I’ve had lipo’s for years and have never seen a fire… yet. I just charge them on a metal pan that I can quickly grab and toss out the window if need be, and I’m always within a couple of feet whenever I’m charging them so I can catch any early warning signs. That’s also something that should be mentioned is that they will typically give an early warning sign that it’s gonna fail and eventually combust. Things like cracking or popping sounds, a funny fruity smell, or the battery is too hot to the touch. If any of these things occur I tend to stop charging and take the battery outside to give a second to cool off before disposing cause at that point there’s no reason to risk using it again just buy another.
New to hobby. And battery stuff confuses me. WL 12428 comes with li-ion 2S 7.4v 1500mah. Just order 2S 7.4v 2200mah 25c lipo. Can I use the same charger? Both use a white balance plug. Output for charger 7.4v 200mah. I know it would take a long time to charge, but im ok with that if its safe.. Thanks for any input 👍
Great information! I use LiPo batteries in my r/c planes and never realized that they should not be stored at max charge. I learn something new on TH-cam!!
Sorry to ask but I just got a car jump starter that has a lithium battery, but I'm not sure where to store it and at what temperature it could go on fire, I'm in Australia, can you please give me some advice the brand I got is called a Certa waterproof portable jump starter from Kogan. Thank you.
Storage charge is 3.85 volts per cell. #11: Don't bang them on the table. #12: Don't pull on the wires. #13: Check the internal resistance of the cells occasionally. If one or more cells gets much higher than the others, dispose of the battery.
Halo, great video. I have some question, what if i use 2 battrey with different mah but same voltage in paralel mode. Will it work fine? Or any suggest and what? Thanks.
I do have one question that’s not put out there a lot. Storing Lipo’s for a month at a time. I use ammo boxes. When putting up at storage charge . How many can r should be put into a ammo box? And is it safe to put 4 r 5 in one box ?
I have read that the C rating is unregulated and therefore a maker can claim any rating they want. I saw a report where various batteries and vendors were tested and none of them came close the the C rating advertised. So what are we to do ?
New to RC here and just trying to educate myself. Glad to have found the channel, but I'm feeling a bit confused with this video. I totally trust what you're saying, I'm just thinking about all cell phones and laptops I've charged through the years without giving it a second thought. How many of us charge our phones in a fire proof safe? 😁
Those are charged at a much smaller rate and the user cannot screw it up. The fact that the rc charger has so many configurations is the dangerous part.
I got a scx24 jeep today! Loads of fun! It came with a cheap charger. So should I get a nicer charger, a "balance charger"? And when I'm not using it I should have it be at like 3.7 volts which i can get too using a storage charger?
Your charger is fine as it's a balance charger for that 2-cell 7.4 volt battery. It's just slow. No need to put it in storage mode. Just leave it at half full when you're not gonna use for a while.
Ok, so your running your car, having a blast, when do you know when is the optimal time to recharge your lipo battery, or change it out for a charged one on the trail as not to wreck the first one? Cheers.
Nice tips and trix... I purchase a traxxas id 4000mah 3s 25c a few years ago and still not used it yet. But it came storage charged and all was good under the whole winter then i did a new storage charged so i hopefully be able to try it out now soon.. But after storage charged it has 44% left and couple of weeks later it has 40% does that sonds any safe or safe if im going to charge them 100% and use it with my ez peak plus charger and im thinking if mycharger stops and beeps if it feels something wrong in the cellpacks when i plug it in. Or what do you say aboat that... Im not sure but it should be like 3.4volt /cell right now
I got a lipo battery a 2200mah 3s to be exact. And a month or so back it suddenly was filled with air but i couldn't seem to see any damage to the cells. Should I get rid of it?
So r zeee battery good or not? They cost about $35.oo for 2 2s. Is that a cheap battery or what battery would you recommend to use on a kaiju. Need help
hello, i have question, one month ago i buy 3 airsoft rifles, and charge every battery for like 2 hours with simple charger what came in box, and now i am working in another country but rifles and batteries staying in my parents house, i gonna stay here for atleast half year, does its safe to storage these batteries? in one month standing there is no problems so far
Can't wait for solid state batteries to be released on the market. They have non of these issues, they last longer, have even longer run times, they charge faster and they're much safer!
@@BuggSmasher there still in development. They're being tested in full sized electric cars. Give it a few years though, the old stock of LIPO and LIFE packs need to be exhausted before Solid State takes over.
What would cause a lipo battery to burst into flames after plugging in the balance and power leads? I have a good charger (C250 Duo). I've charged other batteries fine, but a brand new one started smoking right away, even before I configured the charger to begin charging. I simply turned on the charger and connected the battery.
Scary as shit. I'm planning charging it in me barbacue and storage there during vacations. I live in Canada, (-25C) are common in winter. That temperature is dangerous for the battery?
Is it okay if you get a battery with a C rating higher than what the vehicle calls for? For example- car calls for 50c and you get a 80c battery? I noticed you touched on getting a lower C rating, but how about higher? Thank you!
Question regarding Mistake 4, do not store the LiPo fully charged. After running my rc car I charge my LiPo for the next run. Is it flammable to leave your LiPo for about a week? Or is it just not recommended for the lifespan of the LiPo?
Hi thanks for this. really useful. Just a quick question. If I store Lipo batteries in a proper place after doing the "storage Charge" (as per Traxxas Chargers) are they completely safe? My understanding is the risk is a lot higher when charging. but if using an original traxxas battery with the traxxas charger in the Balance charge mode, only before using and when done using the Storage charge for storage, then it should be perfectly safe. correct ?? or are the batteries so unstable the EVEN with the limited storage charge they can ignite/explode while in storage? thanks in advance.
Hey my friend i make 2s 18650 each one its 3000 mah 3.7v What the best recommend setting for charging i have hota d6 pro charger waiting for reply i hope and thx 🙏
Thank you for the lesson. Rule 7 and 8 are what I am happy with. I requested a custom high C rating for my mountainboard which has regen braking and high output for uphill climbing. Also, I have two batteries for the motors, a separate 36v 10amp and 36v 40amp big block to let one work at then let the other rest
How do I know which is the correct C rating for my use. I have just ordered a TRX4 sport kit with a 16T 5 slot 1850kv brushed motor. Is there a secret calculation that can be applied. Thanks in anticipation. And thank you for your videos, I am learning a great deal from them. Cheers. Alan. UK
So I just bought my first crawler and purchased a Gens Ace 7.4 5000mah battery, my charger doesn’t say anything about storage voltage, pretty much just plug it in and it starts charging, should I buy a different charger with more options? Also what is a good charger that isn’t too expensive, thank you in advance!
I’m a beginner RC pilot. I saw videos of lipos exploding, & decided to by a good charger. My 1st plane came with a cheap charger, I never used. The charger wasn’t cheap, but has multiple settings (balance & storage are all I’ve used) & is simple for a novice to operate. Oh! It charges two batteries at once, convenient.
Between his bias toward axial’s crap, & misinformation about things like lipos, fuck this guy. I’m done with this channel. Literally trying to get people to burn down their houses. Jackass.
Thanks, that was very helpful. I have just started to use LiPo batteries and this tutorial has helped a lot. Can you recommend a charger as mine are older and I would like an up to date one?
I play airsoft, and the battery I use is a Lipo 11.1v I usually recharge it the day before the game and then the next morning I go play. So if I come from the game I need to put it on storage mode via the charger? And if I charge it only do test something at home, I cant by any means have the battery at 100% (12.6v) for more tha one day?
When I started out with fpv quads I had trouble finding how many amps to charge batteries at. I thought maybe 2 amps per battery was probably safe. My phone charges at 2 amps. 1c, 2c. I didn't know what that meant. I was charging 520mah and 450mah batteries at 2amps each. The batteries never got hot or even warm so I thought it was fine. Then I finally found out what 1c meant. I should have been charging my 450mah batteries at 0.4 or 0.5 amps. Not 2 amps. Now it takes 45 to 1 hour to charge batteries, not 15 to 20 minutes like it use to. So I was lucky to not start a fire or damage a battery. I always checked battery temp and checked to see if the charger, wires to the parallel board, or the power wire to the wall plug ever got warm. They never did but I was still charging too fast. I do have a question. I know charging at 1c is the safest, but is it considered unsafe to charge at 2c? My 1100 4s, and 13004s batteries charge up in about 45 minutes at 1c. For some reason my 1500mah China Hobby Line 4s batteries take at least an hour at 1c. My charger ISDT 608ac is capable of up to 8 amps, but I never have gone that high. Charging two 1500mah 4s batteries on a parallel board is charged at 3 amps for 1c.
@@RCReviewChannel I think i will stay by my Sony Konion VTC5A 18650 and LG HG2 18650 and first when someone can guarantee me safe use of lipo batteries in my Ecigarettes i will think about a switch to it
cheers man...just trying to get into RC and your channel is helping. waiting for my first RC...trx-4 sport. finding out about these new Lipos nowadays and not the old nimh/nicd etc. looking at my old Tamya cheap truck from years ago thanks
How off balance is too off balance? Mine are sometimes .05 volts off after I charge them. I know it's not ideal but how off balance until it is dangerous/concerning? Thank you!
Off balance by .1 is where it starts to become a concern. But really .5 volt is where there is a risk and only if you're not balance charging. One cell can be 4.2 volts an the other will be 4.7 at full charge and that's when they can really puff up.
@@RCReviewChannel I'm checking the cells with a device after it charges and it never goes above 4.2 per cell. Normally 4.2 for one cell and a little less on the other
Very informative video. Great for beginners to the world of LiPo batteries. One thing however. You state a storage charge of 3.7v per cell. All my chargers are factory set to 3.8v for storage. Not a lot of difference but this may confuse some people.
its actually 3.8 volts for storage mode, that's the voltage when it degrades the battery the least. Also, you can discharge a lithium ion battery down to 2 volts, it won't cause much damage, but its not preferable.
You say put a hot lipo battery on ice to cool down. Is cooling down say lithium polymer too fast a bad thing to do or no? Like putting it on ice to cool down fast.... great video!!
We haven’t tried this ourselves. But the couple people have mentioned it. I think it’s mostly for extreme situations for folks are in a hurry. But it doesn’t make sense to put the battery in a cool place maybe a refrigerator temperature and you know above freezing level to cool it down quicker than normal.
@@RCReviewChannel yeah I know temps below 40° are hard on lipo and below 20° are extremely hard but that's during use / puttin load on the lipo not storage. Low temps cut discharge amperage by 50% and shorten lifespan of cells.
The safest way is 100% of the time. Most chargers today balance charge 100% of the time. It's not necessary but one really can't reliably tell when it's needed. So it's safest to do every time. It does not take any extra time if the battery is already balanced. To be clear, when when the battery is charged with the balance plug on, it is balance charging.

I meant to say this originally, but went off topic...Was so pissed at myself I went the other way on safety, I built a lipo bunker box with a self extinguishing feature using AFFF. Well, not the real stuff, but it's cheap to make, baking soda with a splash of Potassium Sorbate mixed, and tossed in the bottom of an old mammo box. Then I rigged a system on the peg board above it, using Folgers coffee can with some white vinegar and splash of dish soap in it, tied to fishing string going down into the ammo box. Fire breaks fishing line, dumps can of vinegar n soap on baking soda lined in bottom of box, poof, you got AFFF knock off, foam. I'm working on making a video on how it works, I'll post here when finished.
thank you. I'll look into a c02. I have a batt-safe now that I purchased today. Glad to know a firefighter recommends it
do you feel like people are forgetting what was perhaps more commonly known about electronics? that they get hot and can catch fire.
I always get a Sharpie and write numbers on my batteries. That way I can effectively rotate them so they all get equal use. I can also keep track of a certain battery if it's not performing on par with the rest of them. Thanks for another informative video!
Yes I do the same and figure most people also number and date their batteries when new too. What I found is important is to always use/charge them in order...1,2,3,4,5,6,7, etc. which creates a pattern and makes a weak battery stand out as well as keeping track of their charge states by memory without guessing. I used to keep a log but found doing that provides enough information to maintain and monitor them. I call it a rule now after doing so exposed a bad charger port on a 4 port multi-charger. Thought it was a bad battery at first.
DATE them also
if you had a better charger you would be able to see the IR of them and you wouldn't need to wonder what is going on with the battery. no need to date them etc.
@@blue03r6 My chargers are quite good actually. But I like numbering identical batteries so they all get equal use. Nothing wrong with knowing how old a battery is either.
@@plasticapple704 but are you actually keeping track of how many cycles they have? Knowing their internal resistance is what you need to know. Also knowing which cells are out of balance. If you don't have a charger that shows you the IR and is capable of balance charging to veey close MV it doesn't matter how much you keep track of things or rotate. That's honestly a waste of time as it doesn't do anything. A good charger such as a icharger 308duo you can actually track all of that with their charging software. But seeing the IR is what you need to see. The more use the higher it goes. And cheap batteries like turnigy come with out of matched cells. The pack is only as good as the worst cell.
great info brother! hopefully you've cut down on newbies burning their houses down!
Our motivation for sure!
The videos of fires REALLY drive your points home. I am relatively new to drones and I did not know ALL of this stuff until now. In the beginning I was leaving my 2s batteries fully charged for months until i learned about leaving them at 50%. Only one swelled, maybe 1-2mm on each side.(it was safely disposed of) Now, I have a very nice battery charger with lots of diagnostics (Which I need to master). This vid showed me I still have a lot to learn.
they're unsafe when charged wrong. They're safe with this knowledge shared.
thank you for the good information.
(and thanks for not having music in the background, that feels really relaxing to me)
Thank you for the video.
İt is the best video i have ever watched about lipo batteries. Thank you for preparing it for us.
NO NO No, you don't throw batteries in the trash, no matter if there is power on or not
Many areas now have "Do Not..." and "Must Recycle..." ordinances in place which prohibit disposal of these in household trash. Check with your local authorities. See section 13.1 of this safety data sheet: www.batteriesplus.com/image/sds-Venom-LithiumPolymer.pdf.
Lithium batteries are neither specifically listed nor exempted from the Federal
Environmental Protection Agency (US EPA) hazardous waste regulations, however they do encourage education with local municipalities involvement: www.epa.gov/sites/production/files/2018-03/documents/timpane_epa_li_slides312_ll_1.pdf
Good point. This will become more and more of an issue as lipos are used so widely and they are getting old. Few cities have the facilities to make disposal accessible.
@@RCReviewChannel almost every store that sells them will have a box to put them in . Homedepo lows ace all have boxes you can dispos them in !
@@RCReviewChannel Yes that's true unfortunately and it's a sign of wishful thinking just like the nuclear waste accumulating. Plutonium-239 (half-life 24,000 years), Technetium-99 (half-life 220,000 years), Iodine-129 (half-life 15.7 million years). Let's just hope technology can catch up and overtake Einstein's warnings and prove he was wrong about the outcome of human nature... (e{a})/t=E.
So true! Might just be us here in Scandinavia, but we've been recycling batteries since at least the 80s and every hardware and electronics store, gas station and most grocery stores have recycling bins. If I see anyone throw batteries in the trash I'm like "You fucking monster!"
I charge and store mine in my woodstove, it's no longer in use(installed gas furnace in shop) but is still attached to the chimney .
Hello sir,
Is it ok when i charge my Lipo Battary with an TP4056 Charger? Thank you ❤
GREAT compiling of valuable information!!! ALL good. 👍👍
The only one I have difficulty with (and it's NOT YOU, it's my situation), I CAN'T afford a bunch of Batteries like seemingly everyone else in the Hobby...
I've got ONE 3S for my FlySky Radios (one between ALL of them), ONE 3S for my Aircraft and a 3S and 2S for my Crawlers.
And those took a long time to acquire! 😖😞
I may be one of the last People to start using Lipos - because I've READ the information and SAW the Videos.
I WAITED until I could save up for a GOOD Lipo/LiFe balance Charger!!! It conditions, inspects, balances, REJECTS charging BAD Batteries...
And will set a Safe, Storage Charge! 👍👍
In a Hobby where I can no longer afford SQUAT, I sure don't want to LOSE what little I have...
Carmine ✈🚂🚙
I just bought my first set of lipo batteries..
This was so helpful, thank you!
Another great lipo battery safety video! Probably the best and informative I've seen to date! Thanks for making these!
As usual,great advice. I for one din't understand the dangers of LiPo's when i 1st got into our great RC hobby untill i had a 1S rip on me when removing it from a drone, plug came off and wires crossed !! luckily it was a 300Mah but boy did it go off like a firework. Lesson learned. 👍🛩🚗
Yeah, imagine an 8S 5000 mah. A short circuit is insane.
You certainly wouldn't be able to pick that up and put it in a LiPo safe bag !!!!!!
Thank you, although im about a year in the hobby, it’s still good to view this video from time to time just to keep awareness.
You spoke about topics no one really spoke to me about on various discord voice chats, this info is very much appreciated.
I'll feel safer at home with what I have learned today.
You stated not to put all the batteries together but end the video with a shelf full of batteries? Lol, what am I missing? Great video! Thank you.
Thanks for the info this is great. I’m just getting back into RC since I was a kid because my kids wanna do it and this is all new to me. Bought a fire bag before I even took the truck out of the box. Now I need a better charger. Thanks for the info.
I have a light on a xt60 that I use to get the last of the charge out after it’s too low to run. I try to fully discharge. #1 reason is my house burnt down because of a battery fire. Thanks for the video, I learned some new stuff.
You're discharging your cells down to zero after a run, and then using them AGAIN??
THAT is a HUGE NO-NO for lipo batteries! If you discharge them down to zero, and then attempt to charge and use them again after that, they CAN become very unstable and self-ignite at ANY point during the very next charging cycle, OR just randomly at ANY time while charged.
It's VERY dangerous to fully discharge lithium cells, and then attempt to use them again. 💥 🔥
@ when I am disposing of a bad battery. Otherwise I don't use it.
Good info! One question though. I have three different chargers, EV Peak QC3, Traxxas EZ Peak Live Dual and ISDT T8, and none of them charge to the same voltage. They don't even balance the same. What on charger says is balanced another charger can say is off by 0.1v or more. If lipos are so sensitive why aren't the chargers more equal?
So it's all about the quality of voltage electronics on your chargers. I would trust the best brand or most expensive as the reference. Ourp Protek 680 and Hobbymate Duo read exactly the same, to .01 volts.
So the lipos are not really that critical in terms of peak voltage. 4.2 volts per cell is the limit and they all shut off around there.... 4.19, 4.21, 4.25, etc.
In a test by friends to blow up lipos, they started getting puffy at 4.5 volts. And the really hissing, fire started at 4.8-4.9 volts. So that is pretty far up there.
I purchased the bar safe box from the description box. I just got my first 6S vehicle and I was watching videos on how much more serious of a battery it is compared to a 2,3 and 4s battery and I figured I’d touch on this video again and just purchased the box
Hi, thank you for the video. You explain things in a way a noob like me can easily understand. I really appreciate that. One additional question: If a fire occurs, what is the best way to try and put it out? Is there a specific type of fire extinguisher to keep on hand? I believe that for grease fires in the kitchen you should never use water as it will only cause the fire to spread, that one should instead attempt to smother the flames using a large thick towel, and or cover the area with baking soda. Thanks again!
They're batteries...it'll ironically result in a _C͟h͟e͟m͟i͟c͟a͟l͟ f͟i͟r͟e͟._ So you would use a Sodium bicarbonate extinguisher; aka class A B; AKAA just a normal extinguisher nothing crazy like buying something expensive & going on TH-cam for the manual that explains all this already.
I'm no fireman, but Instead of asking a busy man a silly question that I could google on my own, I just come here Instead to educate you & help alleviate headaches from those who ask silly questions.
The best ever review !
I have a Trial Electric Bike and anyone has told me so full information !!
Thanks a lot!
So glad to hear.
Thanks my friend for the great information and safety tips. I wasn't aware of the dangers. But I never charge my batteries unattended and gave great battery appropriate charges.
Before watching this video I was going to parallel connect two 72 volt lithium batteries for longer range. One is 35 ah and the other one is 17.5. Combined 52.5 amp hour. Whit my components I would of gotten 150 kms. Give or take,depending on riding style,top speed, rider weight road grade(incline.decline).wind ,tire pressure,and outside temperature . I am not doing that cause it something. If bad happens,there go both of my batteries and they are very expensive. Thanks for the great advice. You mat have saved me alot of unnessscary problems.
Right on. Maximizing fun and safety through sharing of experiences is our goal.
ONE OF THE BEST VID FOR NEW LIPO USERS SIR,GREAT JOB!!!!!
Thank you very much. When it comes to lipos knowledge is safety.
Great Video!! I'm just getting into flying FPV and my biggest concern is with these Lipo Batteries. Wow!! Just seems like so many things can go wrong....Excellent video...I'm trying to learn as much as I can before I even try to charge one of these things. Must admit...they make me very nervous. Hope this video gets a ton of views!! Again..nicely done.
Thank you. Given the knowledge... they're very safe. So it was important for us to make this video and inform.
Bought batteries with a much too low C-rating once (my first fpv drone). The battery lost power extremely fast, performance became unreliable and all of the sudden the battery was at 2,6V/cell and super hot and puffy. Good thing it was a cold and dry winter so little to no risk of fire spreading. Speaking of which, is there any way of predicting how much power a model will suck down or is it trial and error? These days I err on the side of caution and pretty much always buy C-ratings of 75+ if possible.
75 = overkill
Nice comprehensive video on Lipo maintenance. Use a Lipo killer to discharge the battery to 0v before disposal. Most Chargers will only discharge to minimum cell voltage. Thanks.
I always put my swollen lipo batterys in salt water, i leave battery for around 3 to 4 days in a bucket to discharge, do not remove once you have placed in salt wateter until 4 days, ihave done this for over twenty years, and disposed of hundreds, thankfully we have great C ratings on batterys today stoping stress on cells giving longer lipo life, discharging a swollen battery with discharge charger is good but i have seen them get agitated and burn up, get an extension lead and discharge in the middle of a open space outside, stay away if you see fire as the gases are strong and temperature can reach 600C, let it burn out no water, i was told over twenty years ago to put them into 20% sea salt to 70% cold water, this information was from a battery manufacturer, the batterys will turn to paper type slug in 4 days making it safe to dispose of in recycling, do this in a open space and away from pets and children and me ;) Stay safe guys and have fun with your toys, don't store lipo batterys in your home, ive come close to house fire in my early days of model flying large aircraft.
Thanks for sharing. =)
I've heard that immersing in salt water is not a good idea. The terminals can corrode before the charge is all gone from the plates of the cells. So I connect my old batteries to some 12v car bulbs and leave them until the bulbs no longer glow - then I put them in salt water for another couple of days.
@@stedenvideos3825 i agree, but ive never had a problem with using salt and water over many years with using 2s-3s-4s-5s-6s, draining with a bulb could put strain on the battery depending on what type of wattage bulb you use-and the voltage of battery, draining with low wattage would be good to trickle discharg and then salt water as you mentioned.
I just won't recommand that because in case of any cell is a little damaged then you will put lithium in your water, water that you will empty in your sink or toilets what is absolutly terrible for nature.
Just fully discharge by connecting to your battery anything that uses curant such as a light bulb for exemple until is is completly empty, now you can also find some lipo-killers in your hobby store.
Nobody was using LIPO cells for
R/C models 25+ years ago....
Been in rc since the early 80s seen the batteries change ,actually raced not just play and seen a many of battery disasters, manly as you say not knowing and stretching the poor battery, and your most definitely right as about chargers ,many times took the ole battery apart moved cells around so they wouldn't mess up ,so many out there no nothing about this ,now we got balance build in the charger ,if they use it
Awesome video. My GEN8 will be my first unit using LiPo batteries.
Great video!
I store my lipos at 3.8V per cell.
That sound perfect.
That is the magic number 💪
I love your videos thank you very much! They are very informative and helpful. Especially since I'm new to the "New RC world" I'm 43yrs old and the last RC I owned was a Traxxas Hawk 2.
So yesterday I purchased the Blue Redcat Gen 8 after numerous videos of reviews/upgrading ect.. ect..
But again thank you for taking the time to explain the very important information we all need to know.
Have a great day and stay safe
What is the good charger for all those issues?
Buy a Venom Pro Quad or Venom Pro Duo and call it a day. Unless you just use Traxxas Lipos and in that case get the Traxxas Ez Peak Dual. I've got the Venom Pro Duo, The Ez Peak Dual, and an Ez Peak single and I've never had any problems and all the Ez Peaks are Beginner friendly the Venom Pro Duo and Quad you need a little more knowledge but it's not rocket science.
I am just getting used to the Lipo Batteries I used to be a nickel Metal hydride guy and I just got used with them. I ran NiCad batteries back in the day when you had to drain them to completely empty and recharge them ,and you only got five minutes out of a race, because a 4 minute race meant you had to use that battery in 4minutes 30 seconds to get the most out gear ratios and specialty brushed motors to win a race. I have a bunch of drills and everything that I use until they're dead and have a backup for them but I currently only running One battery with my trx4 blazer it's a 3-cell 4000 will it hurt it when I come back from a half an hour or 45 minute cruise to the woods to balance the battery on the charger? Until the next time I take it out a couple days later?
Excellent presentation. I subscribed for obvious reasons. Like not being a fan of burning down my house due to being ignorant of LiPO battery characteristics. Thanks for your presentation and warnings.
Another very nice thing about having 2 or more battery packs is that you'll be easily able to tell if something is going wrong with one of them. If one of the packs is suddenly losing punch or runtime, it's much easier to have another pack to compare it to. Using just one all the time, you may not notice the abnormal degradation if you don't have another one to compare it to.
Thank you! You have become one of my favorite sources of info.
👉💪
Right on. We enjoy sharing for fun and safety.
For storage I have a lipo bag but wanted to know which area would be better for storage. A outside shaded shed with temperature fluctuations because of outside Temps with seasons or inside home with steady ambient Temps. I'm hesitant with indoor inside home. I have no garage only a tuff shed like the ones from home depot. Like a little house style.
Hi,I have some doubts why is there a continuous spark when I try to connect my lipo battery (2200 mah 11.1 volt 3s 30c) to my esc (30a) and is it because of friction
Second thing the battery i mentioned above also showed the voltage in negative when I checked is with my multimeter.
What happens when they freeze? I like in Minnesota and it gets below freezing in my garage sometimes.
When they freeze, their output decreases by up to 40%. It goes back to normal when room temperatures are back.
Freezing is ok if not too much, i heard some people store battery long in freezer.
you can NEVER under estimate the danger of badly treated and maintained lipos ... well said
I don’t use lipo’s for rc’s but I do use them with my Airsoft guns and this information is still very useful thanks. I understand that you can never be too safe but I’ve had lipo’s for years and have never seen a fire… yet. I just charge them on a metal pan that I can quickly grab and toss out the window if need be, and I’m always within a couple of feet whenever I’m charging them so I can catch any early warning signs. That’s also something that should be mentioned is that they will typically give an early warning sign that it’s gonna fail and eventually combust. Things like cracking or popping sounds, a funny fruity smell, or the battery is too hot to the touch. If any of these things occur I tend to stop charging and take the battery outside to give a second to cool off before disposing cause at that point there’s no reason to risk using it again just buy another.
New to hobby. And battery stuff confuses me. WL 12428 comes with li-ion 2S 7.4v 1500mah. Just order 2S 7.4v 2200mah 25c lipo. Can I use the same charger? Both use a white balance plug. Output for charger 7.4v 200mah. I know it would take a long time to charge, but im ok with that if its safe.. Thanks for any input 👍
Great information! I use LiPo batteries in my r/c planes and never realized that they should not be stored at max charge. I learn something new on TH-cam!!
Sorry to ask but I just got a car jump starter that has a lithium battery, but I'm not sure where to store it and at what temperature it could go on fire, I'm in Australia, can you please give me some advice the brand I got is called a Certa waterproof portable jump starter from Kogan. Thank you.
Storage charge is 3.85 volts per cell. #11: Don't bang them on the table. #12: Don't pull on the wires. #13: Check the internal resistance of the cells occasionally. If one or more cells gets much higher than the others, dispose of the battery.
The I.R. of most of my "good" cells are in the single digits... once a LIPO cell gets to around 25+, I consider it garbage at that point.
Halo, great video. I have some question, what if i use 2 battrey with different mah but same voltage in paralel mode. Will it work fine? Or any suggest and what? Thanks.
Good video.. understand that owning an adult rc car or helicopter with lipo batteries.. comes with an amazing amount of responsibility!!!
I do have one question that’s not put out there a lot. Storing Lipo’s for a month at a time. I use ammo boxes. When putting up at storage charge . How many can r should be put into a ammo box? And is it safe to put 4 r 5 in one box ?
How do feel about disposing of LiPo in a salt water solution? After a few days soaking then in the trash.
I have read that the C rating is unregulated and therefore a maker can claim any rating they want. I saw a report where various batteries and vendors were tested and none of them
came close the the C rating advertised. So what are we to do ?
New to RC here and just trying to educate myself. Glad to have found the channel, but I'm feeling a bit confused with this video. I totally trust what you're saying, I'm just thinking about all cell phones and laptops I've charged through the years without giving it a second thought.
How many of us charge our phones in a fire proof safe? 😁
Those are charged at a much smaller rate and the user cannot screw it up. The fact that the rc charger has so many configurations is the dangerous part.
Thank you for all the great content you put out in your videos, it’s been very helpful to me!
This is our goal. Not to scare or to discourage but to inform and share.
Thank you for doing this. It's so important that people understand about Lipo's.
I got a scx24 jeep today! Loads of fun! It came with a cheap charger. So should I get a nicer charger, a "balance charger"? And when I'm not using it I should have it be at like 3.7 volts which i can get too using a storage charger?
Your charger is fine as it's a balance charger for that 2-cell 7.4 volt battery. It's just slow.
No need to put it in storage mode. Just leave it at half full when you're not gonna use for a while.
@@RCReviewChannel okay, thank you!
This newbie says THANK YOU
👍😎
❤
How do you balance charge?
on the buying only 1 battery thing. what if my lipo doesn't get hot, is it still stressing the battery?
Thanks for getting this info out there. Quite a lot of folk abuse their batteries badly. Hopefully this will help someone.👌👍
Ok, so your running your car, having a blast, when do you know when is the optimal time to recharge your lipo battery, or change it out for a charged one on the trail as not to wreck the first one? Cheers.
Nice tips and trix... I purchase a traxxas id 4000mah 3s 25c a few years ago and still not used it yet. But it came storage charged and all was good under the whole winter then i did a new storage charged so i hopefully be able to try it out now soon.. But after storage charged it has 44% left and couple of weeks later it has 40% does that sonds any safe or safe if im going to charge them 100% and use it with my ez peak plus charger and im thinking if mycharger stops and beeps if it feels something wrong in the cellpacks when i plug it in. Or what do you say aboat that... Im not sure but it should be like 3.4volt /cell right now
I got a lipo battery a 2200mah 3s to be exact. And a month or so back it suddenly was filled with air but i couldn't seem to see any damage to the cells. Should I get rid of it?
Always good info whether you're new at using Lipo batteries or just need a reminder to be safe and take care of your investment.
Im charging 12x 6s 1300mah lipos daily parallel does a lipo save even work at this type of Explosion?
Can this happen to other batteries like Nimh or Li-on?
So r zeee battery good or not? They cost about $35.oo for 2 2s. Is that a cheap battery or what battery would you recommend to use on a kaiju. Need help
hello, i have question, one month ago i buy 3 airsoft rifles, and charge every battery for like 2 hours with simple charger what came in box, and now i am working in another country but rifles and batteries staying in my parents house, i gonna stay here for atleast half year, does its safe to storage these batteries? in one month standing there is no problems so far
Exactly what I needed to see. Great video. Thank you
Can't wait for solid state batteries to be released on the market. They have non of these issues, they last longer, have even longer run times, they charge faster and they're much safer!
Seriously? When are these being released?
Seriously? When are these being released?
@@BuggSmasher there still in development. They're being tested in full sized electric cars. Give it a few years though, the old stock of LIPO and LIFE packs need to be exhausted before Solid State takes over.
AND much more expensive!
@@Gamleprofil they're said to cost LESS then LIPO packs!
What would cause a lipo battery to burst into flames after plugging in the balance and power leads? I have a good charger (C250 Duo). I've charged other batteries fine, but a brand new one started smoking right away, even before I configured the charger to begin charging. I simply turned on the charger and connected the battery.
great review do you know if the noco boost plus gb40 1000a 12 v ultra safe portable lithium jump starter safe to use and keep in car thanks
Scary as shit.
I'm planning charging it in me barbacue and storage there during vacations.
I live in Canada, (-25C) are common in winter. That temperature is dangerous for the battery?
yup. good idea. or cinder blocks.
That's actually what I do! Haha!
@@dillonwest9732
Finally I went for 3 Li-Fes
Here in Japan are easy to find but are much more expensive.
Is it okay if you get a battery with a C rating higher than what the vehicle calls for? For example- car calls for 50c and you get a 80c battery? I noticed you touched on getting a lower C rating, but how about higher? Thank you!
Question regarding Mistake 4, do not store the LiPo fully charged. After running my rc car I charge my LiPo for the next run. Is it flammable to leave your LiPo for about a week? Or is it just not recommended for the lifespan of the LiPo?
No, this is not a problem at all. Storage is more like 3-9 months... for seasonal rc'ers.
Hi thanks for this. really useful. Just a quick question. If I store Lipo batteries in a proper place after doing the "storage Charge" (as per Traxxas Chargers) are they completely safe? My understanding is the risk is a lot higher when charging. but if using an original traxxas battery with the traxxas charger in the Balance charge mode, only before using and when done using the Storage charge for storage, then it should be perfectly safe. correct ?? or are the batteries so unstable the EVEN with the limited storage charge they can ignite/explode while in storage?
thanks in advance.
They are perfectly safe in storage mode. As long as the wires are very good and there's no chance of a short, they will be secure.
@@RCReviewChannel thanks!!!
Excellent video mate, good sound advice, this video has probably saved hundreds of lipo batteries catching fire & causing immense damage.
Stay Safe 🙏🏻
Hey my friend i make 2s 18650 each one its 3000 mah 3.7v
What the best recommend setting for charging i have hota d6 pro charger waiting for reply i hope and thx 🙏
one of the most helpful videos
Except a lot of the information provided is either incorrect or just outright dishonest and dangerous.
good! can i use a (army green) metal box and get the lipo in and charge plz ?ty
I’m wondering also
Nice job and very helpful. Thanks
Thank you for the lesson. Rule 7 and 8 are what I am happy with. I requested a custom high C rating for my mountainboard which has regen braking and high output for uphill climbing.
Also, I have two batteries for the motors, a separate 36v 10amp and 36v 40amp big block to let one work at then let the other rest
How do I know which is the correct C rating for my use. I have just ordered a TRX4 sport kit with a 16T 5 slot 1850kv brushed motor. Is there a secret calculation that can be applied. Thanks in anticipation. And thank you for your videos, I am learning a great deal from them.
Cheers. Alan. UK
Yes
Traxxas VXL3s system has a good cut off right? I’m using a 3S lipo.
Yes, the cutoff is good. Just needs to be turned on.
So I just bought my first crawler and purchased a Gens Ace 7.4 5000mah battery, my charger doesn’t say anything about storage voltage, pretty much just plug it in and it starts charging, should I buy a different charger with more options? Also what is a good charger that isn’t too expensive, thank you in advance!
Check out hobbyking for good chargers. If you found a nice one, check on some reviews online. Thats my tip
I’m a beginner RC pilot. I saw videos of lipos exploding, & decided to by a good charger. My 1st plane came with a cheap charger, I never used. The charger wasn’t cheap, but has multiple settings (balance & storage are all I’ve used) & is simple for a novice to operate. Oh! It charges two batteries at once, convenient.
ISDT Q6 lite and a 24v psu, you can also get a parallel charging board for it and charge multiple batteries at once.
But 3.7v is about 20% left in the battery. You should be storing them at around 50% charged, or 3.85v
Correct.
I was gonna say I've always heard 3.8 to 3.85 for storage.... 3.7 seems low
3.8v to 3.85v per cell is the standard.
Between his bias toward axial’s crap, & misinformation about things like lipos, fuck this guy. I’m done with this channel. Literally trying to get people to burn down their houses. Jackass.
KaotikRC ...plus the fact most laptops, phones, etc use lithium ion, not polymer... this guy doesn’t know what the fuck he’s talking about
Thanks, that was very helpful. I have just started to use LiPo batteries and this tutorial has helped a lot. Can you recommend a charger as mine are older and I would like an up to date one?
I play airsoft, and the battery I use is a Lipo 11.1v I usually recharge it the day before the game and then the next morning I go play. So if I come from the game I need to put it on storage mode via the charger? And if I charge it only do test something at home, I cant by any means have the battery at 100% (12.6v) for more tha one day?
When I started out with fpv quads I had trouble finding how many amps to charge batteries at. I thought maybe 2 amps per battery was probably safe. My phone charges at 2 amps. 1c, 2c. I didn't know what that meant. I was charging 520mah and 450mah batteries at 2amps each. The batteries never got hot or even warm so I thought it was fine. Then I finally found out what 1c meant. I should have been charging my 450mah batteries at 0.4 or 0.5 amps. Not 2 amps. Now it takes 45 to 1 hour to charge batteries, not 15 to 20 minutes like it use to. So I was lucky to not start a fire or damage a battery. I always checked battery temp and checked to see if the charger, wires to the parallel board, or the power wire to the wall plug ever got warm. They never did but I was still charging too fast.
I do have a question. I know charging at 1c is the safest, but is it considered unsafe to charge at 2c? My 1100 4s, and 13004s batteries charge up in about 45 minutes at 1c. For some reason my 1500mah China Hobby Line 4s batteries take at least an hour at 1c. My charger ISDT 608ac is capable of up to 8 amps, but I never have gone that high. Charging two 1500mah 4s batteries on a parallel board is charged at 3 amps for 1c.
Thank you so much, you answered so much of my questions, due to using Lipo in ecigarettes.
Yes, so many got burned with ecigarettes in our research. And most our mouth injuries.
@@RCReviewChannel I think i will stay by my Sony Konion VTC5A 18650 and LG HG2 18650 and first when someone can guarantee me safe use of lipo batteries in my Ecigarettes i will think about a switch to it
cheers man...just trying to get into RC and your channel is helping. waiting for my first RC...trx-4 sport. finding out about these new Lipos nowadays and not the old nimh/nicd etc. looking at my old Tamya cheap truck from years ago thanks
That is so cool to hear. Yes, everything is funner and safer with knowledge so we are trying to share the insight.
Thank you for your video. I recently got into rc cars again (after 25 years). So much has changed and I was a bit overwhelmed. This helped
You can do it! We keep getting back in to after a lifetime of rc and this lipo thing was a big change.
All my favorite lipos are puffed; 10 year old Thunder Tiger 3s 2100's that work great!
_LOL_
You right. Next step: have to merry them.
How off balance is too off balance? Mine are sometimes .05 volts off after I charge them. I know it's not ideal but how off balance until it is dangerous/concerning? Thank you!
Off balance by .1 is where it starts to become a concern. But really .5 volt is where there is a risk and only if you're not balance charging.
One cell can be 4.2 volts an the other will be 4.7 at full charge and that's when they can really puff up.
@@RCReviewChannel I'm checking the cells with a device after it charges and it never goes above 4.2 per cell. Normally 4.2 for one cell and a little less on the other
What is the disposal voltage for the battery please ?
The safest is zero. Plug directly onto a motor or small bulb. Most chargers will discharge only to 3.3 volts per cell and that is ok too.
Very informative video. Great for beginners to the world of LiPo batteries. One thing however. You state a storage charge of 3.7v per cell. All my chargers are factory set to 3.8v for storage. Not a lot of difference but this may confuse some people.
Knowledge keeps us safe when having fun.
its actually 3.8 volts for storage mode, that's the voltage when it degrades the battery the least. Also, you can discharge a lithium ion battery down to 2 volts, it won't cause much damage, but its not preferable.
You say put a hot lipo battery on ice to cool down. Is cooling down say lithium polymer too fast a bad thing to do or no? Like putting it on ice to cool down fast.... great video!!
We haven’t tried this ourselves. But the couple people have mentioned it. I think it’s mostly for extreme situations for folks are in a hurry. But it doesn’t make sense to put the battery in a cool place maybe a refrigerator temperature and you know above freezing level to cool it down quicker than normal.
@@RCReviewChannel yeah I know temps below 40° are hard on lipo and below 20° are extremely hard but that's during use / puttin load on the lipo not storage. Low temps cut discharge amperage by 50% and shorten lifespan of cells.
How often should you balance charger?
The safest way is 100% of the time. Most chargers today balance charge 100% of the time. It's not necessary but one really can't reliably tell when it's needed. So it's safest to do every time. It does not take any extra time if the battery is already balanced.
To be clear, when when the battery is charged with the balance plug on, it is balance charging.
