BMS caught on fire. What did I do wrong?

How you detect which of balance wires you should connect? I use voltmeter, connect minus wire to voltmeter and check all the wires, the first one should be 3.70V and each next wire should have +3.70V more then previous one.

This is for using the BMS for charge only (BMS bypassed)

Also, the extra balance wire connection (if there is one) is USUALLY on the negative end but you must check the balance lead voltages with a multimeter and read the BMS pcb or documentation.

Ohh. Thanks. My bad.
