Product Q&A
Q:How do I judge what material my battery is?
A:
Check the battery body voltage. If it 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?
A:
Ensure the number of cells in series in your battery pack matches the protection circuit board. The board must be the same series count as your pack.
Q:What material is your battery?
A:
We provide protection boards for both LiFePo4 and Li-ion batteries. LiFePo4 has different electric parameters, so please specify if you need it for LiFePo4.
Q:Do we need cell balance or not?
A:
Yes, balance is needed because cells in parallel and series cannot be identical. The balance function groups cells with similar performance.
Q:Do you have Minimum Order Requirement (MOQ)?
A:
No, we do not have an MOQ. We can provide various capacities and sizes per your requirements. OEM/ODM is welcome.
