1.Connect Battery B- with BMS B- firstly! 2.Connect Battery 1 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.
