Product Q&A

Q:How do I identify the material of my battery?

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?

Ensure the number of cells in series matches your battery pack. Also, confirm the battery material, as LiFePo4 has different electrical parameters than other batteries.

Q:Do we need cell balance for our battery pack?

Yes, because individual cells in parallel and series cannot be identical. Balance functions ensure cells with similar performance work together effectively.

Q:What is the Minimum Order Quantity (MOQ)?

We do not have an MOQ. We can provide various capacities and sizes according to your requirements, and ODM/OEM is welcome.

Q:What are the terms of payment?

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