Tips for charging
Regarding the charging voltage:
Based on the characteristics of Lithium Iron Phosphate (LiFePO4) batteries, the voltage may appear
higher during the charging process. The battery voltage will stabilize to the actual voltage
approximately 15 minutes after the charging process.
Charging methods:
Use a 28.8V lithium battery charger to maximize the capacity. Recommended charging voltage:
between 28.4V and 29.2V. Recommended charging current:
0,2C: The battery will be fully charged in approximately 5 hours..
0,5C: The battery will be charged to around 97% in approximately 2 hours.
Inverter/charge controller:
Select "24V Lithium (LiFePO4) mode" or "User mode" to enter the values according to the
