FAQ

Q:  Can I use this protection circuit board for my battery?

 A: Can use this protection circuit board, or not? There are 2 questions:How much cells in series is your battery pack?  

The protection circuit board you need to buy must be same cells in series as your battery pack.

What material is your battery? Only the LiFePo4 battery has different electric parameter from other battery,

so if you need buy the protection circuit board for LiFePo4 battery , Please let us know firstly.

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 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.

Any further questions, Welcome to contact our sales person by sending inquiry . Your satisfaction is our pleasure. Let’s Join for mutual Benefits!
