Product Q&A

Q:How do I identify the battery material type?

Check the battery body voltage. If the normal voltage 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 for confirmation.

Q:How do I determine if this board fits my battery?

The number of cells in series in your battery pack must match the protection circuit board. Ensure the series count is identical before purchasing.

Q:Do I need cell balancing function?

Yes. Since individual cells have slight performance differences, balancing is necessary to group cells with similar performance and ensure optimal battery health.

Q:What is the minimum order quantity (MOQ)?

There is no MOQ. We accept various capacities and sizes per your requirements. ODM and OEM services are also welcome.

Q:Is this board suitable for LiFePo4 batteries?

LiFePo4 batteries have different electric parameters. Please inform us if you need a protection board specifically for LiFePo4 batteries so we can provide the correct specifications.
