Product Q&A

Q:How do I determine the battery material type?

Check the battery body voltage: 3.2V indicates LiFePo4, while 3.6V or 3.7V indicates Li-ion or Li-polymer. You can also ask the manufacturer.

Q:How do I select the correct protection board for my battery?

Ensure the board's series count matches your battery pack's cells. Also, confirm the battery material, as LiFePo4 has different parameters than other types.

Q:Is cell balancing necessary for my battery pack?

Yes, balancing ensures consistent voltage across cells. Without it, voltage inconsistency occurs after charging due to natural cell performance variations.

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

There is no MOQ. We accept various capacities and sizes based on your requirements, and OEM/ODM services are welcome.

Q:What payment terms are accepted?

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