Help Battery warms up! #if you DIY do it properlY

I think I can get those from the Mechanic I work for.

Looking at the charging time one battery must be dead or disconnected it recharges roughly half the time it used to and the battery doesn’t warm up while charging, is that a good sign?

So open it up, check voltages for each p-group.

Also check voltages from the 1st group progressively to the last. Measure from main neg terminal to pos on cell 1, then 2 etc… All the way to 14. You should get progressively higher voltages as you do each new cell.

Take lots of pics, especially if you see burn marks anywhere. Clear your work space of all metal. Use a plastic or ceramic knife to remove the shrink wrap. Cover exposed connections when not in use.

Be very careful

Report back and post lots of pictures.

Pretty sure it got wet…

Could the batter temp wire occasionally shorting be the reason for the sudden loss of battery?

Defiantly moisture in there and metal showing on the corner of the cells

I think I don’t need to measure the cells. Is the battery savable? Like let it dry out and hope for the best sort of style?

Wow. Take it outside your home, send it to appropriate facility for recycle, and be happy that you haven’t started a fire while riding it. That is a disaster waiting to happen, that battery.

I would stop using that battery immediately, also highly suggest you don’t store it in the house if possible

Even before you shorted the charge port and you doused it in water the series connections look to be good for like 15amps max.

Consider yourself very lucky homie. That’s a fire waiting to happen. If your other pack is from the same place I’d stop using it as well. Even before the pack got wet there’s sooo much wrong with it.

I actually hoped I could do something like that evapo rust and just use electrician tape to isolate the cells :sweat_smile:

I don’t know how much it can do, it was the standard battery coming with the board

Yeah figured that

The other one is from a different board brand but I guess not much better

Well, you don’t know until you see what’s inside it. I’d open it up and take some pics.

And this right here is why I took the leap into building my own packs. There’s no standards out there for many board manufacturers re battery safety. E-bikes too.

Take that thing outside until u can diapose of it properly.

Well the other pack is in the small enclosure which it’s basically molded to, I know for sure that’s dry. The first one was just opened to often and then not properly sealed anymore…

out of curiosity, what esc are you using with that setup?
14S is not that common
