 About the battery BMS/PCB/PCM
 

Function: Detect and protect the battery from over-charge  ,over-dicharge, over-current short-circuit ,temperature detecting protection and auotmatically voltage balance function .

Build with high end electronic components (High End IC and MOSFET ) ,simple structure design will let it have more stable quality working performance , Flexible application ( it can be used for less series battery by leaving some connection pins at empty status ),full set of protection measures let it works well without any infulence from external unexpected accidents.

Wiring:

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

 2. Connect Battery1,Battery2,Battwey3,Battery4 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.
