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 . 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.

FAQ
Q: How do I judge what material my battery is ?
A: Please take a look at the battery body.if the normal voltage of
your battery shows as 3.2V,the battery will be
LiFePo4.If the normal voltage of your battery shows as 3.6V or
3.7V, the battery will be Li-ion or Li-polymer battery. you can
also ask battery manufacturer the material of battery.
Q: Can I use this protection circuit board for my battery?
A: Can use this protection circuit board, or not? There are 2
questions:How much cells in series is your battery
pack? The protection circuit board you need to buy must be same
cells in series as your battery pack.What material is your battery?
Only the LiFePo4 battery has different electric parameter from
other battery, so if you need buy the protection circuit board for
LiFePo4 battery , Please let us know firstly.
Q: Do we need cell balance or not?
A: The function of balance : Since battery is made of many pcs of
cells in parallel and in series, the cells can't be
the same as no two people in the world is the same , so can only
put in group with similar performance is not
consistent , which will lead to each cell voltage is not consistent
as well after the completion of the charging if
without balance fun
Q: Do you have Minimum Order Requirement (MOQ)?
A: No, We don’t have MOQ, Different customer have different
requirement ,We can provide various capacity and size is per your
requirements,Also ODM / OEM is welcome.
