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 sales or technical support before buying.

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

For different port wiring, the cathode of the charger and load is different. For same port wiring, the cathode is the same, and charging current equals discharge current.

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

The equilibrium function discharges high voltage cells via resistors to match low voltage cells, ensuring consistent cell voltage and improving overall battery performance.

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

No, we do not have an MOQ. We can provide various capacities and sizes per your requirements, and ODM/OEM is welcome.

Q:What is your term of payment?

We accept PayPal and T/T (Telegraphic Transfer).
