Just tried to assemble my build after finishing soldering and when everything was connected and I turned the board on, I got a spark between the positive battery’s balance cable and the series balance connector. I immediately disconnected it and made sure no part got fried, nothing was hot except for the BMS.
These are the electronics of the board:
I don’t know much about electronics and what I do know is from building this board, one thing that seemed pretty weird is that the BMS gets warm (not very hot) whenever the balance cable is connected, not sure if that’s normal or also some kind of problem.
Batteries are two 3s’s in series to make a 6s, the BMS is a 6s BMS, so I don’t see where the problem is. Any help appreciated, I’m clueless. Thanks
