Scabbage what is this
I miss these old flite test videos. Coming back to re watch them brings good memories.
New to RC. You guys bring alot of great knowledge for me. Keep em coming!!
Thanks flight test....i learned the hard way about LiPo safety last summer when i left my lipo charging in the back of my car and went inside the house , half hr latter i was helping the fire department put out my car lost it and all my planes and tx!
Wow that sucks, hope by now you have more planes than you did 6 years ago
R.I.P lesson learned
This video is making me a bit paranoid now, I can't stop thinking that my lipos are going to kill me!
I've not got to the end of the video yet, but the section on charging and balanced charging has pretty much answered 4 of the questions I've had for quite a while.
This is the EXACT type of video I have been looking for being new to flying FPV Rc's. Thanks a lot.
Hey guys! Thank you for this video. I have often searched the Internet for important information and when I find it it is in terms that electrical engineers can understand. Thank you for the easy to understand (ETU) that you've provided. :)
Great video, I mean it ...! I was always the old school hobbyist believing EPO and batteries had no place with in this hobby and to use it was sacrileges at best.. But I guess the world is changing and so must I....! So thanks for teaching an old dog a new trick...!
this is a really good series. accessible yet diligent. the pro is very earnest and it makes you want to learn!
You guys forgot an important thing... There is an optimal amount of charge for storage with LiPo batteries...
Optamizm
Ikr?
What is it?
3.85 V per Cell
Which is better for RC :Li-ion or LiPo battery?
Great tutorial guys. Just one other thing that could have been mentioned would have been an explanation of storage charge. If you know you're not going to use your battery for an extended period never leave it in a fully charged or discharged state but instead use your charger to take it up/down to a safe storage charge level. Regards = Nidge
This is the exact information I'm looking for.
You guys are brilliant.I am going to hunt out all your other beginner series episodes.
I am a newbie and have acquired three Lipo chargers in the last few weeks yet I had no idea how dangerous these Lipos can be.
I refer a lot of people who are trying to get into the hobby to your beginner series. Great work guys!
Excellent video guys! I am enjoying these beginner series videos learning lots of useful information. Keep up the great work.
Thank you guys for this, I have it saved and always come back to it and this series.
LOL, both informative and funny. Thanks. I enjoyed it even though I'm pretty familiar with batteries. One of the best battery explanation videos out there.
Thanks guys, i just ordered everything needed to make your Batbone Tri-copter I can not wait until i can get to build/fly it
As an old bloke trying to get into rc flying this is an invaluable resource, Thank you.
Thanks guys, you have really helped me and a lot of other people! My super cub should be in the air soon. Thanks again! :)
Thanks for the time You took explaining proper use of batteries. I am new to lipo ‘s and the info was much needed and explained in a way even a slow learner such as myself am now more confident charging and discharging lipos. I very much enjoy Your other informative videos. Keep up the good work and God Bless.
More on picking/using a computerized charger would be *greatly* appreciated! And power supplies too of course!
Once you guys are finished with the 10 part series it would be great to get it all on a DVD or as a download, my friends ask me all the time about getting into the hobby and I think these videos all together would be a good start for them.
How do they not have TH-cam..?
Newbie here says massive thanks! So much learned in 20 mins.
6 years later and this video is still useful and relevant. For me at least. Though probably wouldn't hurt to check if there is any new or updated safety tips to add. Could be a good throwback vid for you guys. Most battery charging videos I seem to keep finding are 4-9 years old.
Josh & Josh; Really Nice battery Review & Thanks for all the information ! Thanks for the Video
Nice video guys, really informative about batteries. I find that using nitro engines on planes is much more less of a hassle but I'm old school. When I started flying rc-planes there wasn't really electric motors, planes around.
Nice work guys, pretty much everything covered. Of course most of us don't get disposal info with batteries but I guess the best method is to discharge using a 12v globe (maybe in an outdoor concrete block), and then twist the +/- wires together before putting in salt water for a week.
I wish Class D fire extinquisher powder was sold in small quantities just for the extra safety, but sand is free.
Good explanation on the C rating and what it means. People are often so confused with that.
I didn't know I was abusing my batteries thank you for this video, very helpful !!!
and 10 minutes is a decent flight length too...
ref: 2:40 ish
Thanks again Joshes for your work in our favorite family fun hobby!!
I'm hooked now, great info....again
Great video sounds like a sand bucket in the hanger is a good idea!
Thanks guys,good episode.
Good show for newbies. Keep up the good work
Where's those calculator links?
exactly wheres the calculator
I may learn this stuff yet! LOL Thanks guys!
Excellent information for novice. Thanks for sharing.
Damn, this is important information. Big Thanks!
Thank you! I'm new to Lipo batteries and it is helped me out a lot. But one thing I didn't understand yet: How do I know the health of my battery, how exactly can I determine if I can still use it? (I use 2200mAh, 3S 11.1V 25C and 35C) It would be great to get an answer for that.
+Ido Kuttner If I may reply, get a capacity checker. You can find them on Ebay for real cheap (around 8 bucks). Do a search on lipo checker or meter. It tells you the status of each cell and how much it is discharged.
excellent ! a great help , thank you for posting .
Im going back to IC. Cant be arsed with all this stuff!!!
I always forget to like but not today this flight Test series is very helpful thank you guys
Thanks very much for posting this.
Appreciate the battery safety tips in addition to spelling out LiPo terminology.
You guys are very helpful thanks 😊
Do you think you could make a swappable EDF?
No words about internal battery resistance? Long non-use of lipo battery? But it's a great lipo beginner video!
Guys, your videos are awesome, thanks!
I have 3 batteries with 7.4V and 2500mAH each!
Can I connect them (2 in series and 1 to others 2 in parallel) to have 14.8V and 5000mAH?
Is this a good idea?
Do they last for engine with 3500KV, 55A and 850W?
Thank you very much! I am always confused in C rating. :)))
thank you guys very informative
Great video guys! I wish I saw this about 2 years ago. Luckily nothing bad happened. The online LiPo explanations can be daunting and very confusing to read for beginners.
I typically stop flying around 3.6 mark, some people even say 3.7 is empty.
Yeah, I always recommend not discharging past the nominal voltage, land at 3.7; that's close enough to following the 80/20 rule. I teach that in my Multirotor 101 classes.
Sometimes its hard to judge the voltage since my fully charged 5a 3s goes down to 4.0v the moment I get in hover. And if I land at 3.65v the voltage returns to 3.8-3.9v. So is 3.7v in hover empty?
Great videos for a noob like me. I'm considering buying additional/bigger batteries. (Current flight time is about 6 minutes.) I have motors with brushes and I've heard I need to let them cool between flights. How long should I let them cool and if I get a battery with more capacity, is that going to destroy the motors? Thanks in advance!
Great video and all, but I don't get the title- what does "safety" mean?
Thx much, good info all the way around
Thanks for reminding about the dangers of life with LiPo's
I have a question, I live up were it is 20 F, I was wondering if that effects the flight time. Please reply, thank you!
awesome stuff
Great video guys! But you guys should have covered storing you lipos for an extended period of time and putting them into storage mode at a voltage of
3.80 volts per cell other wise if you leave them charged or discharged for a week or more they can start to break down and puff on their own. I always put my lipos into storage mode even if im only going to be waiting 2 days until the next time I fly. I have been flying my custom built H-Quad for almost a year now and I'm still on my first set of lipos, but I did have one get punctured and catch on fire in my hours. Talk about brown pants level scared. I was lucky that I reacted fast enough and grabbed the battery by the wires, jumped off my balcony, ran out the front door and put the garden hose on it for about 10 min. BE SAFE WITH YOUR LIPOS, OTHERWISE YOU WILL CRAP YOUR PANTS!!!
Got the same question about how to storage lipos. Charged or uncharged? for longer or shorter periods like months and weeks. Also what is the best way to storage lipos? i got a special bag when i charge and when i storage them when not using the lipos or is there any better way to storage like special boxes ect thx in advance!
I have a 3 cell lipo that was slightly melted by a soldering iron. Should I still use the battery? If not then What should I do with it?
Also, where in a house would it be safe to charge or store it? Do I really have to put it in a bucket of sand or a fireproof case when I charge it or can I just put it on a table?
Now you've made me worry that my house will burn down if I keep batteries inside.... what if a battery explodes.... you mean I now have a load of active time bombs in my house that could catch fire at any moment....?
I’m going to make the assumption that since Amps (Amperes) is current, the “C” may stand for current. Don’t take my word for it as it is just a guess. Thank you for producing this series, I’m learning heaps and soon my mate Spade who got me onto Flite Test will be teaching me to fly, Helicopters I can fly but planes he’s going to teach me :)
A very current topic.
Very helpful!! I have a quick question though, I have a 3 cell 2200 mah Lipo that has a 25c rating. On an average size rc plane, how long would the plane fly for? How would I find out? Also, the lipos I bought from amazon came with their own charger that they say is set to properly charge them. Is this charger legit because I am not too keen on buying an 80 dollar LiPo Charger?
Very Nice.
Nice video, but I was hoping you could address static current readings vs. under load. Do I land when the voltage gets to 3.3 volts during operation (ie via connected volt meter), or do I go by the reading on the ground after landing? Hard to find consistent info on this point.
The little connectors, like on a 7.4v , how do you get those apart once you’ve plugged them in? My fingers are too big.
I have a battery question for y'all. I have a plane that says it needs a 4 cell setup, but I ordered some 3 cell batteries with the same discharge rate. The plane is a dynam devil 3d running a 650kv motor, 50 amp speed control, 13 x 6 prop, and a 3 cell 2200mah 25C battery. Think that battery will cut it on the plane? Or will it just blow up or be gutless in the air? I see yall running 2 cells on 3 cell setup planes, so can you do the same running a 3 cell on a 4 cell plane setup?
Thanks good video.What is a safe Voltage for storing Li-Po ?
I would like to see a video on how to chose and set up batteries with your equipment..like can you use your battery on a quadcoter for a camera and motors at the same time? What are the option..Thanks for your great videos guys..
Somebody please answer this. If I got a battery that's way over the c rating I need for my quad, can it still fly safely? Say i can only pull 64 amps far extreme yet I got a 40C (82 amp) battery?
Hey guys! I am brand new to the hobby. I still don't understand my strange attraction to flight but whatever, I think I'm hooked! So, my Horizon Delta Ray just arrived and I'm reading the directions. I come to the battery charging section and it tells me that I can get an AC adapter for the DC car charger and the amps limit should be 1.5A. I aready knew about about the AC adapter and got one from Horizon, but the amps out is 2.2A. Will I hurt my Delta Ray batteries using this AC adapter?
Yes, you can check the Viewer Request Speed Challenge episode in the end, they crashed nose down
Awesome videos guys keep it up :D I just orderd my first cessna 182 rc plane today :P Thanks to you i got interested and started to fly :D Relax i have a sim so i hopfully wount crash it the first 3 sec :P
is the plane still living?
I'm surprised the A123 cells didn't catch on for RC. I've made a few packs from those and they work great, and they are nowhere near as prone to damage as LiPo cells.
I had a 4cell battery that was in perfect shape brand new but one of the calls was low and it wouldn't charger so I decided to carefully remove the dead cell. And let me tell you that battery was perfect after that. Now it's a 3cell and runs great.
Got a question. I got my new Turnigy nano-tech 1300ma,11.1v 3s battery. I checked the the voltage(at the xt60 plug) it reads 11.4v. Is this safe? Also should I do a discharge and or balance cycle with my charger first before doing a first charge? Thanks in advance for answering my noob questions!!
Just figured it out i think.
what do you guys think about the new idea of amazon drones
So I have a couple handfuls of those little baby 1s 150mah batteries that I can't use anymore. So, to dispose them properly, soak them in salt water and then?
How do you determine how much flight time you can get out of a battery and your setup?
can i put 2 BAT in paralele mode for more mAh? ( AKA more air time ) do i need a spectial modular for that ? or is it possibal?
Rather interesting question: In almost everything I have read about LiPos there is mention about charging and storing in fireproof containers... Yet, I never see it explained in detail and I never see anyone actually doing it that way.
So..
1. Do you recommend sticking the battery into a fireproof bag while charging?
2. Do you store batteries at storage-voltage in a fireproof bag? I so, 1 per bag? As many as you can fit? etc?
actually what i do is that I put all my batteries in a surplus ammo can, it is pretty fire proof that if one of them or all of them caught on fire, nothing will pass through it , actually i transfer the batteries by my car while they are inside the ammo can (even the life battery for my Tx) ... i don't have enough fireproof bags to put all my batteries in , but the 2200 mAh is in one fireproof bag....this is for storage
for charging , i put the battery in a fireproof bag and charge it, then remove it and put another one inside it and charge it .. for more safety,, i put the fireproof bag inside a trashcan , it is metal and that because i charge inside my house and i think that is much safer
***** Thanks for the advice. I've been looking at ammo containers on eBay. Will get one soon.
biglightbt Good to know, thanks! I'm very careful about all those things. My comment was a few months ago. Since then I've learned a lot. I am getting both a lipo bag and an ammo case, just for extra security. But currently, I'm flying a couple of batteries and I'm simply treating them nicely and never discharging them under 80%. Again, thanks!
as a chemistry student that has seen some serious shit go down, including eight lithium cells shorting out and burning, meh. the fire hazzard isnt too bad there is a ridiculus amount of lipo cells out there, we dont hear about them all burning/exploding all the time..
I use the BAT-SAFE to charge and store my batteries. They are $50-60, and well worth the insurance. You could put a paper towel on top, explode the battery, and the paper wouldn't catch fire. As importantly, it will filter the black soot out of the smoke. The fumes are still extremely toxic. If your battery blows, even in a lipo sack, you will still experience massive smoke damage, even if nothing catches fire. Before I owned my bat-safes, I used to charge my batteries in my oven.....with the oven off, of course.
Hey guys, how would you store your lipos for when you have down time due to winter weather?
I wonder when you guys are going to do a video on battery swap mods like using 18650 batteries in place of stock Li-Po packs you find on most quadcopters and such. Want to see if a quad can use one of these in place of a stock 1S battery.
If two motors have a limit of 14v can I wire a 6s battery in series to double the flight time with a safe voltage
curious, so you'd mentioned 9.9 v ? so when flying should I set my timer to 9.9 v to land or I can stop and land with 3 v?
9.9 is 3.3V/cell. So yes, that's where you want it. That gives you a safe-range to bring it down. (I've got mine set to warn me at 32% and kill the motor at 30% to protect the battery. That's 10.2V for mine that the motor dies.) That 2% gives me about a minute to get it down and pop flaps before it turns into a glider.
What battery chargers do you guys suggest for a new person to the hobby that will grow with me?
They are crazy important, what is more important, wings, motor? Is there insane crazy important? Good video, good info!
Some thoughts on storage voltage would be nice. 3.85v per cell is what i understand. Question is, is the a certain amount of elapsed time when you should consider putting the lipo in storage state? I would imagine if its only going to sit for a few days, might as well leave it fully charged...
hi.
how about the storage conditions in terms of temperature? What is common for LiPo's?
thx
Hi Josh & Josh i am new to this hobby. I connected a Emax simonK 20A ESC to a XA2212 980kv motor and i connected all to a 2s 4500 mah 25C battery.. mesh i think i burn the esc.. So i want to know what is the max mah i can use for the ESC.
tks
What battery should I use for a 2200 kv brushless motor with a 30a esc?
How do I store batteries? In a lipo bag obviously but how charged should they be? And if I don't have a charger that smartly puts it at the specific charge level how do I get it there?
I'm having a hard time choosing a charger. There's a lot of useful information here but the batteries on the Flite Test store have an odd looking connector and I can't figure out what type of charger to buy for them. Any help?
Hi,
I have tried to find info on on C rating and I do not mean the 1C, 2C and so on when u charge, got that covered. I mean the C rating with the burst 10-15sec.
I now have a battery that is Zippy 5800mha 30C and burst 40C and that one is also recommended for my quadcopter F450 (stock) with Nasa M Lite + GPS.
Question:
Can i buy a 40C,50C or 60C battery to my quad or will that damage the components?
I also wanna say thank you! Flite Test for all the videos and beginner series, keep them coming :)
Best Regards

Helo,
I'm a beginner and some point is not clear for me in the RC electronic system. I would like to ask you that can it causeing some problem if I use a 2800mAh 11.1V 30C battery with a ZTW Beatles 20amps ESC 2-6LiPo what is connected to a SUNNYSKY Angel Series A2208-1260KV 2-3S Airplane Outrunner Brushless Motor (max continuous current: 13A) The propeller size is 1047. So my question is that this battery with the 84A can destroy the ESC or the motor? Or the ESC takes only that amount of amps what the motor and the rest of the parts needs? Will it works with these parameters?
After using my 2200 3 cell @35-70c in my quad the pack is warm, so is this normal?
Can you do video on proper disposal of lips batteries?
I am an old hand from the NiCad days, so these lipos are new to me. my charger will do more than lipo, but it does not have a discharge mode. how do I get my batteries into discharge for storage voltage. running the motor seems like a bad idea due to heat buildup.
I think that ether my 3s 10000mah is to heavy for my drone or my throttle is to low. I try to fly my tarot fy690s with 750kv motors and 1355 propellers but it does want to lift. Do you think that a 3s 10000 mah is to heavy?
