About the battery BMS/PCB/PCM

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.

5. FAQ

Q:  How many Ampere protection circuit boards should choose?

A: It depends on your load power such as electric motor power please contact the sales or technical support before buying.

Q:  What is the distinction between same port wiring and different port wiring?

A: The cathode of charger and load is different for different port wiring , the cathode of charger and load is same for same port wiring and the charging current is equal to the discharge current. 

Q:  What is the distinction between balance and unbalance function?

A: Equilibrium function is that high voltage cells will be discharged with resistor, waiting for the low voltage cells , to achieve the each cell voltage is consistent , to improve the battery performance for the whole group.

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,
