How To Discharge Your R/C LiPo Batteries - Fast! 

Another great video! Thanks mate for the awesome information!

Very well explain my friend thank you for the breakdown 💯👌🏾 very useful info 👊🏾👑

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.

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!

Great as usual Brett .....

"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.

Funny and informative video, well done Brett!

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!

Great video. Always helpful videos. Wish I lived in chico

skyrc really good product. using it very often. good video

Wierd i just put a battery on discharge and this video shows up. Is my phone creeping on me🤔

GREAT STUFF BUDDY KEITH

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)

According to your math, I need that Skyrc BD200! Going to use my amain points before they expire. :)

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

great video

Great Info 😎😎😎😎😎😎😎

Confused but informed 🤪

0:17 seriously can't stop laughing. Comedy gold, putting on the sunglasses.

I remember the most high tech thing was that relay that was used with a voltage cut off for NICAD’s no more having to watch for the bulbs to dim on the homemade dischargers.

I always discharge them to storage mode with a lipo checker and a 12 V light bulb, works perfect for me.

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.

Thanks for the info. I didn’t know this was a problem that I had, I just assumed it’s supposed to take forever to discharge in my chargers....wait, is this some kind of sneaky marketing? 😉 Cause it’s working...😋

even when the charger says 3 or 4 amp discharge rate, they usually only do like .3 or .4

I take it out the balance wire and it works i need a pro to show me or tell me

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).

I know every Amain video is trying to sell me something. Good thing I like buying RC gadgets!

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 RU-vid 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

I remember dumping the batteries using those homemade strings of lights 😂

Nice vid

"DISCHARGE LASAGNA" IS NOT SOMETHING THAT SHOULD EVER, EVER BE SAID OUT LOUD LMAO!!!!!1!

Thank You Very Much😇😁😀

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.

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.

So I am getting back into the hobby and have a few lipos that I have learned i am not treating as well as I should be from your videos. In this and the mistakes video you mention *storage voltage but never say what that recommended voltage is (or I completely missed it both times!). I assume it is around the 3.7 volts per cell but wanted to make sure. Thanks for these videos as I learned a lot. I was charging them to full and leaving them sit for weeks so I will not be doing this any more :)

You make good videos all the time. When discharging with the light bulb method & that many bulbs the sunglasses are a must but next time don't forget the hotdogs and a stick. I just use the junsi 106 for my needs.

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

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.

just got the ISDT FD100 . theres a jack connector on it. do we connect it to pro q6 or do we need the battery check by ISDT, please advice

Can you make a video on how you made the battery discharge light 😆😆

Is this what I would need to fully discharge a 4s battery? I have a d6 duo pro, but how much faster will this be able to retire a battery over a d6 duo pro? Thanks!

I have the skyrc 200w discharger, but the voltage reading is way off when you set your end voltage

WHAT about a 4s Battery plug into a smart charger is it 14.8 volts and 5amps how do i properly charge a smart charger hit the 1 or 2 BUTTON. First or hit the middle button first And spin it to.properly get the Right amps. And volts with the Smart charger Brett cause when i plug it in the 1or 2 holes then plug the prong in beside THE orange plug cause it Error something then i have to start all over Again then i take THE prong that that the orange cord plugs in mext to

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

I new to LiPo Batteries, I have 2s 7.4 5000mAh 100c. After each use are u meant to discharge it then put it into storage charge. Or can u just put it into storage charge. What would the amps be for storage and discharge for this LiPo. Ur videos are 👍 great job.

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.

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.

I was interested in discharging lipos, but immediately after starting the video I had to check out David Cutter, amazing!

Never had to bust out the calculator with my nitro or gasser. Turn it upside down open the fill cap discharged done.

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?

Does this apply to Li-ion batteries as well? If not, what's the proper storage voltage for Li-ion batteries?

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?

Great Jimmy Stewart hahaha😂

I would like to see the set up for the icharger 304. You know if you can

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 ?

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.

Una forma muy cara de hacerlo.

My charger is a basic one with no discharge how do I know what’s a safe storage voltage

👌 so I can't mess up my lipo by discharging through my charger? I don't mind if its slow.

Storage vs discharge for cycling/ rejuvenating older batteries?

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??

Those were the good old days!

so can you discharge at any Rate you want and it wont affect the lipo or do you need to keep it under a certain current depending on the C Rating of the Battery

it is any traxxas lipo battery??

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?

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?

Dose the Sky RC BD200 have a function that automatically puts your battery in storage mode ?

Maybe a stupid question. But i am new in this world. Does this do the same thing as using storage mode on my charger?

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.

Wot wot? i thought my light bulb theory was fool proof :)

So once you discharge the lipo you can store it away? Or is there another process

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

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?

For $20 use the AOKoda 150W 6s discharger/balancer and voltage checker, win win.

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

How do I discharge a 7,4 lipo that only got a balance lead? The + and - is build in on the battery. ( it is a battery for a airsoft gun)

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. I LOVE IT JUST HAVE TO. HANDS DOWN USED TO THE SYSTEM.

Omggg what r c car was that doing that mile long wheelie that was some Impressive throttling control 🔥🔥🔥🔥💯💯💯💯🤝🏿🤝🏿🤝🏿

Hey, since my charger indicates the approximate % of charge of my 3s lipo, is it fine if I just stop charging when it’s at about 50%? Then when i want to go out with my RC again I just fully charge it. thanks!

Oh I know what my discharge is… it’s 5w, extremely frustrating and why I’m watching this lol.

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?😊😮😁

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.

SPECTRUM SMART CHARGER IS CONFUSING MY CHARGER FINISHED CHARGING IN 25 MINUTES 4.20 VOLTAGE CAN'T REMEMBER THE AMPS BUTS ITS ON FAST CHARGE IS THAT SAFE BRETT THE TRUCK SEEMS TO RUN OKAY AFTER ITS CHARGED UP AND READY TO RUN JUST REALLY CONFUSING EVEN WATCHING THE VIDEO'S SO I HOPEFULLY I'M NOT DOING ANYTHING WRONG WITH THE VOLTAGE READINGS AND AMPS READINGS THE. BATTERY IS SUPPOSED TO KNOW RIGHT AWAY WHAT VOLTAGE AND AMP READINGS WHERE TO GO TO RIGHT AWAY TO RECHARGE BATTERY FROM BATTERY CHARGER RIGHT BRETT??

I'm trying to discharge my lipos for trash. Is there technology for that? Thanks,Good video!

While using the BD200, does it keep the cells balanced while discharging?

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

So I have a tenergy charger but it doesn’t have a storage mode and I use my lipo for airsoft, can I just keep shooting it till it’s like 50 percent battery and then just go store it

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 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 ?

Hi sir I want a wireless battery discharger

Is he the guy from the losi ads when i was little

I think what isn't known as I have been out of RCs for 25yrs are the small details. I just bought my little son and I brand new trucks. A lot has changed since then. The questions no one is saying is 1) why do I need to discharge it 2) do I have to do this every single day we go out and recharge every single day we want to go as this seems ridiculous 3) what are these explosions everyone is having every week from their batteries? I spoke to some and theyve never had an issue. Others make it seem like its a love grenade ready to explode at any moment.

Is it a bad thing to take a fully charged lipo Battery and discharge it by running it in storage mode

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 :)

What Billy maze was to oxy clean infomercials and what joe rogan is to MMA brett is the ambassador to the RC world.

My method is : BASH BASH CRASH BASH YET

I need one, the other day I needed to discharge batteries, so I put the vehicle on a stand, and cranked my throttle trim until the wheels started moving. Not fast enough to damage hub carriers or bearings, snd it was taking forever. So I just had to keep doing short speed runs till the lipos were at 3.8VDC

I didn’t do this and now my battery’s are bubbling up

Can u discharge a puffy lipo or its to risky

Im confused. Whats that 8.4v? Isnt 2s 7.4v? 3.7v per cell😅
