Wiring:
1. First connect the B- of the BMS to the total negative pole of the battery pack;

2.The cable starts from the thin black one connecting B-, the second red wire connects the positive pole of the first string of batteries, and the next string is connected in turn to positive pole of the battery,B-,B1,B2……B24; then insert the cable into the BMS; (The maximum number of strings is 4-30 strings, the example picture is 24 strings) (Please weld the wires in order and avoid pseudo solder joints.)  
3. Connect Charger C-/Load P- with BMS C-/P- (Use larger size wires) 
4. Connect Positive Pole: Charger C+/Load P+ with Battery Pack B+ (Use larger size wires) .
