Wierd i just put a battery on discharge and this video shows up. Is my phone creeping on me🤔
Always does
Yup
Yh it's used to personalize advertising
Yes
Not weird.
"DISCHARGE LASAGNA" IS NOT SOMETHING THAT SHOULD EVER, EVER BE SAID OUT LOUD LMAO!!!!!1!
LOL!!!
Haha, ok. It made me hungry too.

@@AMain_Hobbies Can you please tell me, why we need to discharge lipo?
any link to read
@@MrNams If for some reason the voltage is higher than the storage voltage, you would want to discharge the battery down. Sometimes, we charge packs but can't use them, that's a good reason to discharge them. When the batteries sit idle unused, they should be at the storage voltage.
-Brett
Sounds cheesy
Confused but informed 🤪
I know every Amain video is trying to sell me something. Good thing I like buying RC gadgets!
According to your math, I need that Skyrc BD200! Going to use my amain points before they expire. :)
It's all about the math! I love it!!! great video, I can't tell you how man times I have had to bust out ohm's law with people on social media, and inevitably they don't get it or don't believe me, lol!
Thanks... this video just saved my butt from screwing up my new 6s lipos (ya I’m new to the whole lipo battery thing lol)
Usually most chargers on storage mode will automatically discharge. Also cheaper chargers the discharge mode takes the battery below storage voltage. So just try using the storage mode for discharging to storage voltage. It will take a while but it's also quite safe because the amp rate is low. ALWAYS CONNECT THE BALANCE LEAD TO THE CHARGER FOR DOING ANYTHING. Simple insurance against many things that can go wrong with the cells.
OK, you have yo explain what that means for people who have been out of the game for 25yrs. What is the balance lead? I mean, wouldn't it be obvious you have to connect the battery wires to the machine in order to charge or discharge? Why did you out it in caps? What will happen if peoole miss your step? Will it explode in your fave blinding your and burning skin? I mean, we don't understand your urgency so you have to explain what and why.
@@TheYoungerSemiOldManalance lead is usually only on lithium batteries with more than one cell. It has one positive connecting to all the cells, and a negative wire for each cell. It is so each cell can reach a voltage of what i think is 4.25 volts (might be lower) and stop. If a cell goes above thE maximum cell voltage (what happens when you charge lithium battery withour balance cable), it will puff up and probably explode
For most other batteries, like ni-mh/cd, those black batteries you can find in kids cars, and a single cell lipo, you dont need a balance cable(they only come with a single cable. It is the same uou will use to charge it and plug into your RC). You just need to not overcharge the batteries, and especially not the lipo (it will have yhe same effect as charging without balance charger on a multi cell battery, it will explode).
I always just use my rc car to discharge my LiPo to then charge it on storage mode after.
Great method Sadman!
-Brett
Why on storage mode im new to electric help!
Antonio Eufracio you put the battery in storage (charge) mode to preserve the battery if your not going to be using them for multiple months. Like I do it during the winter when I’m not using my rc car. It helps preserve the life of the Lipo battery.
Sadman Chowdhury you discharge after it reaches the volts you put the storage to right?
@@adrian7008 If the battery is fully charged play with it in your car to discharge the battery until it's empty or near empty then charge it in storage mode on your charger. Having the battery in storage mode will keep the battery at a good level for 6 - 10 months.
Funny and informative video, well done Brett!
I didn’t even know these existed I’m definitely going to be ordering one I have a lot of crawlers and trail trucks also some large monster trucks sometimes I end up not using all the batteries are charged and my desktop charger takes for ever to discharge because it will only discharge at one amp
Oof one amp 😬
I'm trying to discharge my lipos for trash. Is there technology for that?
Thanks,Good video!
Discharge the battery like normal on your charger if possible. Then prepare a plastic container (do not use metal) of cold water, and mix in ½ cup of salt per gallon of water, and drop in the battery. Allow the battery to remain in the tub of salt water for at least 2 weeks. This salt bath will neutralize any remaining power in the battery.
-Brett
I discharge by running em hard. But sometimes you charge up but get sidetracked. I use spectrum 3 days latter it’s discharged it’s self. I know they are expensive but it’s very easy and convient to use.
While a charger's discharge ability is "decent", I'm in complete agreement on using a dedicated discharger. A lot of people will probably recommend the iSDT FD100, or even the FD200. After reading several reviews on iSDT products, I decided to avoid their entire product line. Searching around, something led me to checking out the Maylibet a12. Even though it has a maximum discharge rate of 120W, it discharges at approximately 8A (I've seen it discharging at 8.2A). Some of its benefits are as follows:
1) It has its own built-in balance board - It accepts 2S-6S, with balancing plug plugged directly into the a12.
2) It doesn't require a power supply - The battery being discharged "IS" the power supply.
3) One-button operation - Press once to turn unit on, press again to start the discharging. If you need to stop discharging, just press the button again.
4) Auto shut-off - This is a "smart discharger", programmed to automatically stop when cells are at 3.80-3.85V, and then it shuts off after cooling (approx another 20 seconds).
5) Informative backlit LCD display - Display shows total voltage, voltage/cell, discharge amperage, elapsed time, mAh discharged, and cell count.
The only down side (if you choose to count this as a "down side") is the price - $70. Compared to the iSDT FD100's $35-40 price, the Maylibet is expensive...but, compared to the iSDT FD200, it's somewhat more affordable. Of course, when you compare the Maylibet a12 against either iSDT discharger, and consider the five benefits mentioned above, the Maqylibet a12 starts looking like a "smart investment". Now, all we need is for AMain to start carrying it (hint, hint).
Do you have a link to it?
-Brett
Appreciate it. We'll check that out.

Excellent information but I got lost with the math -- as usual. I'm sure the manual that comes with the device will help or I'll just watch this video again. Thanks, Brett.
Awh shoot. Dang math.

Very well explain my friend thank you for the breakdown 💯👌🏾 very useful info 👊🏾👑
Thank
You
Very
Much😇😁😀
skyrc really good product. using it very often. good video
I always discharge them to storage mode with a lipo checker and a 12 V light bulb, works perfect for me.
thanks
I actually use an old Harley headlight and a lipo checker
I remember dumping the batteries using those homemade strings of lights 😂
September 1989 my dad was cooking fries on the stove when he decided to go run the battery dead on his RC car....
Long story short, the grease caught fire and our house burned to the ground.
Don't do that....
Is he the guy from the losi ads when i was little
"Back in my day..." we called that "dumping" the battery, and it was also thought to help break the "hairs" and "memory" of the older NiCd packs.
AmainHobbies is the best and most informative hobbyshop you will ever find!..Bought lots of stuff from you guys online on eBay and you have great TH-cam informational videos..My question is how do you properly discharge a Traxxas 2s or 3s lipo ID connector style battery, after you only use about half of its power running your RC..WITHOUT having to fully run it down through your RC model?.. meaning I just want to run a crawler for 20 or 30 minutes and be done..How do you discharge LiPo battery pack to a safe level (3.4-3.2 volts per cell I believe)
WITHOUT running it down in your RC?...Thanks
great video as always ... i used to use a light bar and battery checker to discharge my lipos, but i lost a few getting side tracked. sooo i bought a bd200 .... i love it, i use it to cycle my race batteries before race day ... best 100 bucks ever!
Im confused. Whats that 8.4v? Isnt 2s 7.4v? 3.7v per cell😅
whats the name of the song in this video like the theme at the beginning
Great video. Always helpful videos. Wish I lived in chico
Oh I know what my discharge is… it’s 5w, extremely frustrating and why I’m watching this lol.
I've had mine for a while. Helps a LOT. I've got to make me a chart for each cell lipo and state what amps and what volts to set it at. You have to set the volts lower than storage (but not much) so they will be at or near storage when they rest after discharging at a high amp load. This can be a safety issue so be VERY careful and pay close attention when discharging each battery on this device. And this all depends on the resistance in the discharge lead that you use for each different connector.
0:17 seriously can't stop laughing. Comedy gold, putting on the sunglasses.
even when the charger says 3 or 4 amp discharge rate, they usually only do like .3 or .4
You forgot, "Up hill, both ways." I've used the light bulbs on my nicads back in the day and look at you, acting all grown up.
What did you do with my Brett?😊😮😁
HA! I never left the shop though.
-Brett
I've seen you nut out at that table.😁
✌🏻😎🏴I use the charger to discharge my batteries. When I actually remember that is. I believe we shouldn’t have to plug in the charger when discharging. Why can’t it use the power from the batteries? It a shame we need to use energy to discharge energy. & a little crazy 🤪
I don't know exactly, but they probably don't have the necessary parts to achieve this. Look how big that SkyRC BD100 is, it requires many electronic parts to drain a battery quickly. Great question.
-Brett
Another great video! Thanks mate for the awesome information!
All battery discharges do not discharge to 3.8
I didn’t do this and now my battery’s are bubbling up
You're Silence of the Lambs
My method is : BASH BASH CRASH BASH YET
i moved away from chico i miss walking into amain hobbys
I use Traxxas batteries, charger, and the voltage checker.
After every run, I always storage charge the batteries. However sometimes I will leave the battery in the vehicle, set the throttle trim to max, and leave it upside down to discharge the battery by running the car.
If I have a LiPo at 4.2V it takes about 3 hours to get down to 3.8V using a 2 cell 5800 mah battery. That seems to be more effective than using the discharge feature on the Traxxas EZ-Peak charger.
I can only do this on my non-Traxxas vehicles, since (for whatever reason) Traxxas vehicles don't have throttle trim
Running your car at max throttle with no load on the wheels is asking to break something. I would run it at like quarter throttle max.
I read you put the lipo batteries in a bucket with salt water.. ????? This sound crazy to me
Only when the LiPo is on it's way out. The salt water bath neutralizes any remaining power inside the LiPo, making it safe to be donated to the electronics recycler.
-Brett
First, I'll let you use my welding helmet so you don't go blind. What I did years ago was made a lead, one end plugs into the battery other end alligator clips. 1 electrical outlet, 1 toaster. You can figure out the hook-up. Needless to say I ate lots of toast but it worked.
Ha! Pretty clever.
-Brett
You forgot to mention for the low budget people in mind, if they have a small lipo charger and a cell checker, some cell checkers also have a discharger built in. While it may be a lot slower than a charger with a discharge feature, it will still get the lipo to the storage capacity.
Great Jimmy Stewart hahaha😂
This is so stupid for just a battery
That was funny
I do rc to avoid math, not do it!
So once you discharge the lipo you can store it away? Or is there another process
Correct. If the battery is fully charged, you'll want to bring it's voltage down to "storage charge" values. If you put a charged battery away for the night, or week or months, it's bad for the lipo battery.
-Brett
Great Info 😎😎😎😎😎😎😎
I'm new to the hobby and confused...if anyone could help me it would be awesome...i have a hitech x2 ac plus black edition could anyone help me find out how to discharge a 3 cell on this...according to my calculations it at 0.9 amps...is that bad and how long will it take?
It is not bad or harmful to the battery at all. That is a perfectly fine, but slow, discharge rate. Just imagine, if your battery probably takes ~45 minutes to charge for example, and that is at a 5 amp charge rate, discharging at 0.9 amp could take hours. That's the meaning behind the message in this video, chargers discharge slowly. Are you using the Storage Mode to discharge? That will bring your cells to the proper and healthy voltage for sitting around idle, regardless if the cells need to be charged or discharged to achieve it.
-Brett
@@AMain_Hobbies is .9 the limit for it tho if it has a limit of 2 amps overall...it has a discharge circuit power rating of 10 watts
@@brandoncleavenger611 0.9A is probably the limit for that particular battery. It all depends on how big or small the battery is. Your charger will do, "up to" 10 Watts, or 2 Amps, whichever ceiling is hit first.
-Brett
Great info, helpful and interesting but (sorry to be negative) Do you think showing an rc car on a busy street is something you want your viewers to emulate?

I have an I charger 406duo with a 40 Amp discharge and it seems to work great. I'm new to the whole lipo thing. Is a 40 Amp discharge to much for mudboss racing and what are good batteries for 12t mudboss racing that will deliver good power. Also ,how many times can I use the same pck in a race day and how long should it rest between charges.
I have the traxxas id ez peak plus charger, im not sure if i can trust the storage charge, when it comes to these batteries, i get extremely paranoid that its not being storage charged. The owner’s manual doesnt really explain how to discharge the battery before recharging the battery for storage either. I cant really find any video or how-to guides that can explain that. I just bought the bundle because i just dropped about 480 dollars on a the traxxas gt4 supra, wheels and drift tires. This is my second 3rd rc car ive owned, second traxxas car, first lip id battery I’ve owned and i pretty much want to keep the battery in tip top shape because i cant afford another battery if this one goes, at the moment.
my brain hurts...i just want healthy batts w/o a lipo fire....and top performance..thanx
Good if you care about the MAX discharge rate, but didn’t talk about the OPTIMUM discharge rate.
Dose the Sky RC BD200 have a function that automatically puts your battery in storage mode ?
No unfortunately. You manually set the end voltage and it gets to work. If you set the end voltage too low for the battery, the BD200 will discharge the battery below a safe level, so it is important the user sets the voltage correctly.
-Brett
AMain Hobbies thanks Brett👍✌️
So if I can set the end voltage below safe levels will it discharge damaged lipos to near enough 0 at very low amps. I’ve cooked a few brushie cans running them at full lipo voltage for hours and I’ve been too lazy to pick up 24v friendly bulbs to power
I want something that discharges in under one minute
Wouldn't that be nice...
-Brett
So I’m genuinely confused on all this.. my regular process is whip around the xmaxx truck til I’m done.. take the batteries out. Charge to full. Wait til next time. But am I suppose to store charge after use instead of fully charge ? Then fully charge later right before I’m ready to go mess around with the truck ?
But am I suppose to store charge after use instead of fully charge ?
>Yes
Then fully charge later right before I’m ready to go mess around with the truck?
>Yes
LiPo batteries are not designed to sit fully charged while not in use. Instead, only fully charge the battery before use. After using them, put them on the charger on the "STORE" mode, which will prepare the battery to be stored away. When you're ready to use the car again at a later time, charge the battery.
-Brett
@@AMain_Hobbies thanks brett !! appreciate the response.
For $20 use the AOKoda 150W 6s discharger/balancer and voltage checker, win win.
Is discharge and storage charge the same thing? I dont understand lipos lol. If i fully charged my battery and dont use it should i discharge it or storage charge
Good question. The discharge mode will discharge your battery down, draining the power until the desired voltage has been reached.
With the storage mode, the charger will either charge or discharge the battery (which ever is needed) until the battery has reached the desired voltage. So with the storage mode, you can put on a fully charged battery or a drained battery, and the charger will know what it needs to do to return the battery to it's optimal state for inactivity, when you store it away.
LiPo batteries like to have about 50% power when they're sitting around unused, and the storage mode makes it happen. I can't remember the last time I used the discharge feature on the charger instead of just using the storage mode for the same job. The discharge feature is more useful with other battery chemistries (non-lipo) but it's still there as an option.
Hope this makes sense.
-Brett
@@AMain_Hobbies thanks bro I really appreciate you taking the time to explain things I have a better understanding of this hobby because of you and you actually respond to your comments much respect to you man I know it's not easy and u r a busy rc superstar lol
I have a brand new battery iits in cell balance storage charge. could i use it now to my 1/10 TRX 4 land rover Difender or should i have to wait fully charged?
You should fully charge the battery before using it. You technically could use the battery at it's storage charge value, but you'd have very little runtime before it dies because it's not charged.
-Brett
@@AMain_Hobbies thank you so much
So I need to order a special discharger and wait a month for shipping while my battery destroys itself. Man LiPos suck so bad.
I have a traxxas erevo 1/10 which takes 2 batteries and I charged one too much. 😂
BD250
Storage vs discharge for cycling/ rejuvenating older batteries?
LiPo's don't need cycling like older battery chemistries did. But leaving them 100% full will harm them which is why we always recommend storage charging them before putting them away for the day.
-Brett
They have been properly stored for 8 years and thought they might need a few cycles to wake up better :)@@AMain_Hobbies
great video
I use bulbs connected to a cell meter. That way the batteries are also balanced. These dischargers don't do that. I wonder why they don't have that feature. If they did I would buy one.

It depends on the discharge capability of your charger, and then what discharger your comparing it to; we talked about more than one discharger in the video. To figure out the discharge capabilities, please follow the instructions outlined in the video.
-Brett
Great as usual Brett .....
Why do u want to discharge a battery?
Because it is unsafe and unhealthy for a LiPo battery to sit unused with 100% charge in it.

-Brett
My charger is a basic one with no discharge how do I know what’s a safe storage voltage
The battery manufacturer probably has a recommended storage value, but with LiPo cells, 3.7V - 3.8V a cell, is a good place for them to sit idle and unused.
-Brett
@@AMain_Hobbies yes but the charger just has lights for charging or fully charged I’m just gonna half charge for storage
BLA BLA BLA BLA BLA BLA
and why do we need to discharge our battery for??....im a newbie in rc world
When a fully charged LiPo sits unused it is damaging to the LiPo. A LiPo should rest at about 50% power when unused.

Ian Maglasang In my case I’m trying to cycle a brand new 6s 5000mah lipo for an airplane a couple times before putting it in the air.

4.20V is the correct voltage for a charged LiPo cell. When I charge, I like to double check that each cell is 4.20V when the battery finishes so I know the battery is being balanced charged properly.
-Brett
@@AMain_Hobbies Thank you BRETT And WHAT'S A SAFE AMPS LEVEL WHEN FULLY CHARGED BRETT??
@@troyflanagan173 Batteries display a voltage not an amperage. The amperage is your charge rate you set in the charger. As your battery gets closer to being fully charged, the charger will slowly lower the amperage. So the amperage may start high, maybe 5A for example, but by the end, it could get down to 0.1A.
-Brett
I take it out the balance wire and it works i need a pro to show me or tell me
Can you make a video on how you made the battery discharge light 😆😆
If I have a fully charged battery and decided I'm not going to use it, can I utilize the STORAGE feature on my charger to automatically set it to the appropriate STORAGE charge?
If you're using a LiPo battery and you have a LiPo Balance Charger with storage mode function, then you should be able to discharge your LiPo using this storage mode function. Will it happen automatically? Probably not. To know how to do it, please read and consult your LiPo Balance Charger instruction manual.

By w/v does he mean max out of both or max bolts and total watt hours

Hello, having lost the zlrc sg906 drone, I have a fully charged modular battery, does anyone know how to download it? Will I have to leave it on? Will it download like this? I do not have imax or any similar device Thank you
Without the Drone, it's going to be hard to discharge that battery; there is an option though. If you do not plan on using that battery again, try this:
Submerge the battery into a bucket or tub of salt water. This container should have a lid, but it does not need to be air-tight. Prepare a plastic container (do not use metal) of water and mix in ½ cup of salt per gallon of water. Drop the battery into the salt water. Allow the battery to remain in the tub of salt water for at least 2 weeks. This salt bath will neutralize any remaining power in the battery. After, remove the Li-Poly battery from the salt water, wrap it in newspaper or paper towels and recycle it at your local electronic recycle center.
Hope that helps.
-Brett
@@AMain_Hobbies Thanks, to discard it, the idea is good but I plan to use it in a few months or less,
The battery is 7.4 v and 2,800 amp, today another light has turned off, I have 2 lights out of 4, in 4 days it would be on, theoretically it would be at 50%, do you think it is okay to keep it for a couple of months without damaging it? thanks
@@fabioralvarez It should be ok since the battery isn't 100% fully charged. A fully charged battery that sits idle will slowly degrade, that's the real harm. You should be ok though.

i have a 3 cell 3300 mah 35c 11.1 v lipo battery.. my second is totally discharged and shows 0v so can i charge that single cell with a B3 imax rc charger? or how should i recover the dead battery cell , i only have the B3 imax rc charger with me.
Unfortunately, if you have a bad cell you need to properly dispose of and recycle the battery.
-Brett
I thought you could not over-discharge beyond the batts safe capability or dangerous conditions result. Just b/c you can doesn't mean you should ?
Sorry, I don't understand your question. LiPo's can be safely discharged until around 3.0V a cell; discharging lower than that is unsafe and not recommended.
-Brett
Hahah that cracked me up when he made the old school reference. I once was caught in a drive by shooting while walking to a hobby shop for a pinion gear lol.
Holy Smokes! Hope you weren't hurt.
-Brett
You said you set your end voltage to 7.4? I mean isn’t that the fully charged voltage? Should have been 3.8 I think.
7.4V is the nominal voltage of a 2S LiPo; fully charged would be 8.4V. Setting the discharge to 7.4V would discharge each cell to 3.8V, which is right where they should be for storage.
-Brett
Is it possible to discharge a custom Li Ion battery so I can recharge it for the intended amount of volts? :) I'm such a noob with this stuff :)
I don't quite understand your question. But making custom batteries is pretty risky my friend; I hope you know what you are doing, and that you are safe. Each individual cell you are using, has a voltage range (it varies on the chemistry) with most Li-Ion cells have a nominal voltage of 3.6V; and 4.10V when charged. For each cell you have in your pack, the voltages add up. 1 cell 3.60V nominal. 2 cell = 7.20V. 3 cell = 10.8V., etc. This is the voltage of the battery, but not the voltage you charge or discharge at. Charging and discharge is executed in terms of Amps. Hope that helps a little Jacob.
-Brett
And how long CAN a fully charged lipo sit, is it ok for overnight? I like to charge my batteries at night unplug them and I usually run it the next morning, I don’t have a discharger or even a digital charger.. I should probably just go to the R/c shop
Yes, sitting overnight is probably ok, unless your battery manufacturer recommends against it, but it should be fine. Try to do it with low frequency.
-Brett
IS THERE ANYTHING SPECIFIC I HAVE TO LOOK FOR WHEN CHARGING THE BATTERY LIKE I'M TALKING ABOUT THE READINGS ON THE CHARGER AND ALSO THE OWNER OF THE STORE HOBBY SAID I WAS DOING EVERYTHING RIGHT SO I DON'T GET IT UNLESS THE 2 COOLING FANS WERE NOT WORKING PROPERLY OR WORKING AT ALL JUST REALLY BAFFLING TECHNOLOGY I KNOW I HAVE TO SPIN THE WHEEL ON THE CHARGER MAYBE I WAS NOT DOING THAT ENOUGH WHEN CHARGING THE CHARGER LIKE I SAID BEFORE VERY CONFUSING BRETT FAST AND TOUGH.

Troy, I recommend you thoroughly read your Battery Charger Instruction Manual. It provides all the information you need on how to use the charger, how to read the interface, what to be looking out for, and how to properly operate it.

What if you want to really fully discharge a lipo battery when you want to dispose it? A discharger will always stop at 3,2V p/cell and cuts off. Is this discharger capable of 100% discharging a lipo?
No, the liability risk to the manufacturer is so great, they would never allow it. We recommend putting the LiPo in a salt bath, as outlined in our ProTek R/C LiPo Manual, under Disposal Procedure at the bottom; check it out: images.amain.com/images/manuals/Li-Poly%20Battery%20Manual.pdf

Is it a bad thing to take a fully charged lipo Battery and discharge it by running it in storage mode
Nah. That's what Storage Mode is for. It is slow to discharge a LiPo that way, but it is effective. To make discharging faster, some of the products in this video are ideal.

Yes BRETT I CHARGE MY BATTERY AND THE VOLTAGE IS ALWAYS BALANCED TO 4.20 TO 4.18 IT STARTS OFF AT ORANGE THEN GREEN SLOWS DOWN AND THEN TURNS TO BLUE BEEPS TWICE THEN CHARGER IS CHARGED AFTER 2 BEEPS I WAS DOING EVERYTHING RIGHT SO I THOUGHT MAYBE I DIDN'T LET THE BATTERY COOL DOWN ENOUGH ON THE TRUCK RUN 3 DAYS AGO WILL THE ENGINE OVERHEAT REALLY FAST DRIVING ON GRASS IN THE PARKS OR SHOULD I FIND A BIG PARKING LOT OR SCHOOL YARD WITH LOTS OF CEMENT OR A SKATE BOARD PARKS??
JUST DON'T KNOW Enough ABOUT THIS TRUCK BLEW THE ENGINE ON MY RUCKUS. AND IT WAS A BRUSHED MOTOR UNTIL I PUT A BRUSHLESS IN AND 1 COOLING FAN THEN NEVER HAD A PROBLEM AFTER THAT EXCEPT FOR OTHER PROBLEMS ON THE TRUCK AND I CLEANED IT SPOTLESS AFTER EVERY RUN CHEAPLY MADE IN MY OPINION PARTS KEPT ON BREAKING ON THE TRUCK SO I SOLD IT FOR $50 DOLLARS AFTER A WHILE COULD NOT GET WHEELS OFF TO CLEANED THEM INSIDE OR OUTSIDE IT WAS A MONEY PIT AND $400 DOLLARS LESS. THEN THE 1 I HAVE NOW THE 4S KRATON WITH BLX HOT MOTOR AND 5000MAH 14.8 BATTERY STX SPECTRUM RADIO SYSTEM ALL SPECTRUM COMPONENTS.
Say you set you discharger to end at 3.85v per cell on a 6s lipo. I have to set the voltage down 22.2v instead of 23.00v for it shut down. Then let the cells rest for a minute to climb up to resting voltage. Other then that it is powerful and fast. Can this be calibrated?
I don't think it can be calibrated no, but we would have to ask SkyRC to be sure.

I use the Traxxas EZ peak live charger and batteries with my X Maxx and worry about none of that.
