Product Q&A

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

Check the battery body voltage. If it shows 3.2V, it is LiFePo4. If it shows 3.6V or 3.7V, it is Li-ion or Li-polymer. You can also ask the battery manufacturer for the material.

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

Ensure the number of series cells in your battery pack matches the board. Also, confirm the battery material, as LiFePo4 has different electric parameters than other types.

Q:Do we need cell balance or not?

Yes, balance is needed because cells in parallel and series cannot be identical. Without balance, cell voltages become inconsistent after charging.

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.
