I have a 10s4p pack I built myself using lg hg2 cells and a bestech d140 10s discharge only bms.
The pack used copper buss bar and each cell was fused.
While assembling. I accidentally let my 12th bms wire short to something. It seemed to still work but stupid me didn’t check voltages of each parallel pack the next day. I’m certain it was wired up correctly other than that mishap. The resistor on the bms got a little brown on the conformal coating from the heat but looked ok otherwise.
I went for a ride last night and noticed I only had 37 volts even though I just charged it. I tried to charge again and it cut off at 37. So I tore the pack down and found the pack attached to the 12th bms wire at 0 volts.
Has anyone else experienced this? I’m currently rebuilding the pack. I had 5 spare batteries from the same lot and the pack only has two charge cycles on it.
