Product Q&A

Q:How do I identify my battery material type?

Check the normal 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 choose the correct BMS for my battery?

Ensure the BMS series matches your battery pack's cell count (e.g., 7S for 7 cells). Also, confirm if your battery is LiFePo4, as it has different parameters.

Q:Why is cell balancing necessary?

Battery cells vary slightly in performance. Balancing ensures consistent voltage across all cells after charging, preventing inconsistency and improving pack life.

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

We do not have an MOQ. We accept various capacities and sizes based on your requirements, and welcome ODM/OEM orders.

Q:What payment terms are accepted?

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