Product Q&A

Q:How do I judge what material my battery is?

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 battery 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 electric parameters.

Q:Do we need cell balance or not?

Balance function is recommended because cells in parallel and series cannot be identical, leading to inconsistent voltages after charging without balance.

Q:Do you have Minimum Order Requirement (MOQ)?

No, we do not have MOQ. We provide various capacities and sizes per requirements, and welcome ODM/OEM.

Q:What is your term of payment?

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