Product Q&A

Q:How do I determine the material of my battery?

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

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

Ensure the number of series cells matches your battery pack. Also, confirm the battery material, as LiFePO4 has different parameters than other types.

Q:Do we need cell balance function?

Yes. Since cells in parallel and series cannot be identical, imbalance leads to inconsistent voltages after charging. Balance function ensures consistency.

Q:What is the Minimum Order Quantity (MOQ)?

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

Q:What are the payment terms?

We accept PayPal, T/T, L/C, and Western Union for payments.
