1. About the 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.Please consult the salesman for specific parameters.
Description:
The protection plate is a semi-finished product, which needs to be used in combination with the battery. Before use, please make sure that the battery is in good consistency (internal resistance voltage multiplying ratio). This product contains technical knowledge. Once installed incorrectly, it will lead to board burning, tube bursting and other situations. Please explain in detail before installation. Novice buyers should install it under the technical guidance.

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,
About your products, just tell us the relative voltage/ cells/ current A or equipment etc,we will help to recommend the most suitable products for you.
