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 structuredesign will let it have more stable quality working performance ,Post-Press Equipment 4. Flexible application (it can be used for lessseries battery by leaving some connection pins at empty status ),5. Full set of protection measures let it works well6. Without any infulence from external unexpected accidents.

FAQ

Q: How do Ijudge what material my battery is ?A: Please take alook 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 Iuse this protection circuit board for my battery?

A: Can use this protection circuit board, or not? There are 2questions: 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 fuIndustrial Customized Service nction 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 lDemonstrational & Teaching Utensil ead 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?

A: Please send messages below or e-mail usand we are always glad to help you with BMS.
