Hey
I have this two year old pack, 17s8p 18650 battery
I do not know how its been treatet by its previus owner. But one cell group is 0,0 the rest is 4,05 volt.
Why do the bms do that? Or is it because i have a bad cell with High ir after two year? Then it will decharge the whole parallel group. Or is it this stuck bms thing, where do i mesure this? Is it on the big transistors that is mounted on the aluminium heatsink?
