Product Q&A

Q:How do I identify the battery material?

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 manufacturer.

Q:Can I use this board for my battery?

The number of cells in series in your battery pack must match the protection circuit board. Ensure they are the same.

Q:What material is your battery?

LiFePo4 batteries have different electric parameters. Please inform us if you need a protection board specifically for LiFePo4 batteries.

Q:Do we need cell balance?

Yes. Since cells in parallel and series cannot be identical, a balance function is necessary to group cells with similar performance.

Q:Is there a Minimum Order Quantity (MOQ)?

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