Product Description
BMS 3S 4S20A li ion Lifepo4 battery pcm for battey pack
About the battery BMS
Function: Detect and protect the battery from over-charge ,over-dicharge, over-current short-circuit ,temperature detecting protection and auotmatically voltage balance function .
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 recomment the most suitable products for you. or we design for you!
