Product Q&A

Q:How do I determine if my battery is LiFePO4 or Li-ion?

Check the battery body voltage. If the normal voltage is 3.2V, it is LiFePO4. If it is 3.6V or 3.7V, it is Li-ion or Li-polymer. You can also ask the manufacturer.

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

Yes, but the number of cells in series in your battery pack must match the protection board. Ensure they are the same.

Q:Do I need cell balancing?

Yes, because cells in parallel and series cannot be identical. Balancing ensures similar performance groups work correctly.

Q:What is the MOQ for this product?

There is no MOQ. We provide various capacities and sizes per requirements. ODM/OEM is welcome.

Q:Is customization available?

Yes, we offer full customization, ODM/OEM services, and flexible designs based on your specific voltage, cell, or current needs.
