So i just finished my 12S batterypack and wanted to connect my BMS System. My BMS is the HCX D196 from Bestech. As soon i connected the JST Plug i’ve seen some little smoke plume, just really really tiny. I’ve checked everything twice but i still have no clue what was wrong. Maybe someone had the same experience like me here… i don’t want to let my battery die because of a stupid mistake…
This is the spot where i think the smoke leaked:
The JST plug with the balancing cables
The B- port
The whole battery pack, i measured from the + to every balance lead, everything correct.
The BMS PCB, top left you see C- (Charging -)
The plan i received with the BMS from Bestech.
