Product Q&A

Q:How many Ampere protection circuit boards should I choose?

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?

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

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

Equilibrium function discharges high voltage cells with a resistor to wait for low voltage cells, achieving consistent cell voltage to improve battery performance for the whole group.

Q:Do you have a Minimum Order Requirement (MOQ)?

No, we don't have MOQ. Different customers have different requirements. We can provide various capacities and sizes per your requirements. ODM/OEM is welcome.

Q:How can we guarantee quality?

We always provide a pre-production sample before mass production and conduct final inspection before shipment.
