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 manufacturer.

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

Ensure the number of series cells matches your battery pack. Also, confirm if it is LiFePo4, as it has different electrical parameters than other battery types.

Q:Do we need cell balance or not?

Yes, balance is needed because cells in series/parallel have inconsistent performance, leading to voltage differences after charging without a balance function.

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

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

Q:What is your term of payment?

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