Product Q&A
Q:How do I judge what material my battery is?
A:
Check the battery body voltage. If normal voltage is 3.2V, it is LiFePo4. If 3.6V or 3.7V, it is Li-ion or Li-polymer. You can also ask the manufacturer.
Q:Can I use this protection circuit board for my battery?
A:
Ensure the number of series cells matches your battery pack. Also, specify if it is LiFePo4, as it has different parameters than other battery types.
Q:Do we need cell balance or not?
A:
Balance is recommended because cells in parallel and series often have inconsistent performance, leading to voltage differences after charging without balance.
Q:Do you have Minimum Order Requirement (MOQ)?
A:
No, we do not have an MOQ. We provide various capacities and sizes per requirements, and ODM/OEM is welcome.
Q:What is your term of payment?
A:
We accept PayPal, T/T, L/C, and Western Union.
