Product Q&A

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

Please take a look at the battery body. If the normal voltage shows as 3.2V, it is LiFePo4. If it shows as 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?

Two questions must be answered: How many cells in series is your battery pack? The board must match the series count. What material is your battery? LiFePo4 has different parameters, so please inform us if buying for LiFePo4.

Q:Do we need cell balance or not?

Yes. Since cells in parallel and series cannot be identical, their voltages will become inconsistent after charging without a balance function.

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

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

Q:What is your term of payment?

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