 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.}
 

Electric Switch, Temperature Switch, Balance, 5V output, NTC and etc, if you need any above accessories, please must to contact our sales fisrt. All items are customized as your requirements, if without any request after order placed, we will produce as original.

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.....B15; then insert the cable into the BMS; (The maximum number of strings is 4-24 strings, the example picture is 15 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) .

About your products,just tell us the relative voltage/ cells/ current A or equipment etc,we will help to recommend the most suitable products for you.
