Frequently Asked Questions
What is the recommended charging voltage?
The charging voltage should not exceed 3.65V, using the CC/CV (Constant Current/Constant Voltage) charging method. Using a compatible LiFePO4 battery charger is strongly recommended.
Can the battery be connected in series or parallel?
Yes. The battery cells can be connected in series and parallel to achieve higher voltage or greater capacity. Proper cell matching and a suitable Battery Management System (BMS) are recommended for battery pack assembly.
Does the battery have a memory effect?
No. LiFePO4 batteries do not suffer from the memory effect, so they can be charged at any time without requiring a full discharge.
Can I order samples before placing a bulk order?
Yes. Sample orders are available for product evaluation, quality verification, and compatibility testing before mass production.
