2.Wiring Diagram
Direction for use Wiring:
1. Connect Battery B- with BMS B- firstly!
2. Connect Battery 1, Battery 2,…Battery 8 with the BMS as the picture shows.
(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) .
Pay attention to make insulation.
