Product Q&A

Q:How many Ampere protection circuit boards should 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 , 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?

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)?

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?

PayPal, T/T, L/C, Any further questions, Welcome to contact our sales person by sending inquiry . Your satisfaction is our pleasure. Let's Join hands for mutual Benefits!
