Is there a fault in my BMS for my 36V battery pack if placing a multimeter lead from C- to B-, and C- to P- outputs 36V? And is this something I can fix, or would I need to replace it?
"B-" is the battery's negative terminal, "C-" is the negative terminal of the charging (input) wire, and "P-" is the negative terminal of the discharging (output) wire.
For some background, I have a few of the same battery packs that eventually stop charging and don't turn on the e-scooter. I have only opened one other battery pack, but I noticed that there are two unbalanced cells in that one.
