Lipo battery meter: amzn.to/2O858QL This will help you determin which cell is bad! Also great for checking battery level and cell differences.
Look scary? Just buy a new battery: amzn.to/2fv4Err
This is what I did to convert a Traxxas 3s lipo into a 2s battery when one of the cells in the pack went bad.
WARNING: There is a fire hazard with doing this, Lipo batteries are very dangerous!

Bro! That floss trick is amazing! Never would have thought of that and it worked perfectly when taking apart a 10S pack that had a bad cell!

When changing a balance plug be VERY sure that the pins are firmly in place. I changed one out and I thought that the pins were ok, but when I pulled the battery from my Tx, 2 pins came out and instantly welded. It was maybe only 3 seconds, but the battery is now totally dead. I was lucky there was no fire!

Wow, I learnt something new today. The Floss for separating and Boxcutter for tabs. Thanks for the insight.

Can you solder on main lead connectors to a lipo that just has a balance cable? Seems fairly easy after watching this. Thank you.

Is there any concern if the voltages are pretty even and run time is normal but there is puffiness? Thanks

I just did this and you did an amazing tutorial but I didn't use heat shrink as a case I used trusty duct tape and some really tough cardboard and it should work pretty good because I've used this type of cardboard with other thing as well.

The balancing socket for 3s is remade in the socket for 2s! You had to remove a red wire from the balancing socket and for plus contact to use a blue wire!!!

Anyone else having to add Venom adaptors to their Floureon batteries? I just ordered a solder station, after I get comfortable I'll go into converting my Venom from a 3s to 2s.

have you had any trouble soldering to the tabs on the lipo? i cant seem to get any to stick no matter what flux or temp this happened on 2 different lipo brands i tryied this on
@continuecrushingrc3653
@continuecrushingrc3653 6 лет назад
It's a pain. I've had a few that I couldn't do because of this exact reason. I just call those a wash and toss them since I don't want to risk issues from something coming loose. Suck though.

Try using a common "T" pin to remove those wires from the plug next time, it works better than that big tip prick you used!

Very informative thanks for posting. Do you store your lipo's in your house I'm new to the hubby and I see a lot of people saying that they dont keep them in there home but I live in a place where keeping them outside is not possible any info would be greatly appreciated thanks
@continuecrushingrc3653
@continuecrushingrc3653 5 лет назад
You need a bag like this: amzn.to/2ST3BUc Although depending on how many batteries you have, I'd get smaller bags for each of them too. If one starts on fire and it's sitting next to the other ones...Keep the lipos stored at proper voltage and you should be okay. You can also keep them in a ceramic pot in the house, too.

do you recommend any certain brand lipo as a good alterative for the Traxxas batteries?
@continuecrushingrc3653
@continuecrushingrc3653 6 лет назад
I've had good luck with Floureon and Venom-but make sure you're cautious of which battery connector you need! The biggest thing for lipo batteries is storage as I find most of the time damaged batteries come from improper storage. Of course regardless of battery manufacturer, they can still have an occasional bad cell after a while. Also you can find a review on a floureon battery on this channel-the cells were very closely matched and performed well. amzn.to/2roFPAy

Thanks. I've really only had one traxxas battery fail my entire time in the hobby, mainly looking for similar performance without the Traxxas price tag.

Hey great vid. Do you have any advice for a 3s 2200 shorty lipo that the 3rd cell charges too fast, and discharges too slowly. Wont balance. That trouble cell is at 4.5 and two others at 3.5 etc... help
@michaelinzitari
@michaelinzitari 3 месяца назад
Discharge it. Dispose it. And next time use balance mode to charge or go back to NIMH. There is no reason for a Lipo to exceed 4.2v per cell
@rsracing-mb1tr
@rsracing-mb1tr 5 лет назад
Can this be done only to lipo?? Or can it be done to nimh or nicd batterys.
@continuecrushingrc3653
@continuecrushingrc3653 5 лет назад
You could do this to nimh/nicd too. You'll need to be able to solder the top of a battery which is usually harder.

Unless you have a small light truck (crawler?) with a huge battery tray this is a dangerous waste of time. Nobody wants a 2S slash. 2S is good for buggy or touring car only.

Anybody that cuts a lipo apart is an idiot you never mess with lipo batteries its not worth a fire because you were too cheap to buy a new one! If one cell is puffy the rest will follow dont be stupid drop it in a bucket of salty water for a day or two and throw it out
