Wiring precautions
First connect the B- of the BMS to the total negative terminal of
the battery pack, Wiring B-, B1, B2... B+, output charge and
discharge negative electrode connected to P-, charge and discharge
positive electrode connected to the total positive electrode,
please wire connection strictly according to the drawing and use
thick cable to connect with P+/ C+/ B+ and P-/ C-
