Product Q&A

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

Check the battery body voltage. If it is 3.2V, it is LiFePo4. If it is 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 cells in series in your battery pack matches the protection circuit board. The board must be the same cells in series as your battery pack.

Q:What material is your battery?

We provide protection circuit boards for LiFePo4 and Li-ion batteries. LiFePo4 has different electric parameters, so please specify if you need a board for LiFePo4.

Q:Do we need cell balance or not?

Yes, balance is needed because cells in parallel and series cannot be identical. The board groups cells with similar performance and includes a balance function.

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

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