Product Q&A
Q:How many Ampere protection circuit boards should I choose?
A:
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?
A:
For different port wiring, the cathode of 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?
A:
The equilibrium function discharges high voltage cells with a resistor to wait for low voltage cells, achieving consistent cell voltage and improving overall battery performance.
Q:Do you have a Minimum Order Requirement (MOQ)?
A:
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?
A:
We accept PayPal, T/T, and L/C.
