Include contact plate very suitable for battery case ,widely use in power tool field:
Feature:
1.True lithum battery pack BMS factory
2.Supply OEM/ODM and custom service
3.High quality with smart balance function
4.Wholesale price
5.Environment
6.Fast delivery
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 recomment the most suitable products for you. or we design for you!
