Our Advantages for BMS
1. Complete Function: Detect and protect the battery from: over-charge, over-dicharge,
over-current, short-circuit,
temperature detecting protection, auotmatically voltage balance function.
2. Build with high end electronic components (High End IC and MOSFET ) ,
3. Simple structure design will let it have more stable quality working performance ,
4. Flexible application ( it can be used for less series battery by leaving some connection pins at empty status ),
5. Full set of protection measures let it works well
6. 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!

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 battery cells 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 function.
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.
Q: What is your term of payment?
A: PayPal, T/T, L/C,Western Union
Q: How to contact for BMS?
