How many people have changed cells in their 6s Lipo batteries?

Just curious.

After dismantling the cells, how do you check each cell to see which one is bad?

What material do you use to put the battery back together? Not the outer wrap, the cells look like they have shipping tape on them. I was wondering if this is a special tape?

Frankly, in the wake of all of the reported lipo fires that have been well documented I can't understand why someone would want to repair a damaged lipo......

I'm sure you will get some replies such as, "I do it all the time without any problems"

But, your stuff, your house, etc......

Flame suit on

Been there, done that and old enough to know better.....

There is a guy at our field that does it often. I have taken batteries apart many times. I have not found replacement cells though.

I do agree that many shouldn't attempt it, BUT it's not rocket science either.

I am an automotive technician, so I am use to tearing into things. The battery is simple.

OH, I do work on electric vehicles and am certified as well. Those batteries you "need" to be scared of! I use to teach classes on these vehicles, and have held several seminars with emergency personnel. These guys really need to know the vehicles before they pull out the jaws of life! I definitely know the hazards of LiPo Batteries.

I have seen where several do repair their batteries.

I am just getting opinions as I hate to throw away 5 good cells on a 6s battery.

If you have a certain process taping the cells back together (after soldering them together), I would be interested in your experiences.

Well, I like to "repair" faulty lipos... We pull the bad cell Out but not to install a new cell.
We do a conversion so, a 6s with one cell bad, you get several combinations... One pack of 5s or two 2s packs...

Lipos for Rx is your chance...or your starter motor for glow or gasser...

Battery repair

unless the cells are IR matched and of the same age I would not repair.

You can however re purpose them by splitting into a smaller packs

I just use duct tape after and write down the pack size

they can be used for other things

spending time, paying attention

Good information above.

I really didn't realize how critical LiPo batteries are. It's very interesting.

IR's, I can check them, but I don't know if I can find one close to donate to a battery that needs one new cell.

I will stay safe vs. sorry.
