Product Q&A

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

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.

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

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

Q:What material is your battery?

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

Q:Do we need cell balance or not?

Yes, balance is necessary because cells in parallel and series cannot be identical. The balance function groups cells with similar performance to ensure safety and efficiency.

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 welcome ODM/OEM orders.
