Product Q&A

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

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

Ensure the series count matches your battery pack. Also, confirm if it is LiFePo4, as it has different parameters than Li-ion/Li-polymer batteries.

Q:Do we need cell balance function?

Yes, balance function is crucial because cells in series/parallel naturally have inconsistent performance, leading to voltage differences after charging without balance.

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

There is no MOQ. We accommodate different customer requirements and offer various capacities, sizes, and ODM/OEM services.

Q:What are the payment terms?

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