 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.


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.
