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,
