Charge Profile for LiFePO4 Batteries

    Many customers ask for the LiFePO4 charging profile after receiving the battery cells and building the battery pack.

    There are many discussions about LiFePO4 charging profiles, but here we recommend using the LiFePO4 profile recommended by will, which is also the most commonly used.

    Charging Profile for Lithium iron phosphate (LiFePO4) Batteries

    Absorption VoltageFloat VoltageInverter Cut-off Voltage
    12V (4S)14.5V13.6V10.7V ~ 12V
    24V (8S)29V27.2V21.4V ~ 24V
    48V (16S)58V54.4V42.8V ~ 48V

    If you want to test battery cell‘s capacity, please test it as the following charge profile.

    Absorption Recommendation for Long Battery Life

    If you want your LiFePO4 cells to last a long time, you can set your absorption to Victron’s custom LiFePO4 charge profile recommendation:

    • 12V Battery: 14.1V
    • 24V Battery: 28.2V
    • 48V Battery: 56.4V

    You can pull full capacity with the absorption figures above, but the charge rate will be reduced at high SOC.

    According to the EVE 3.2V LiFePO4 battery cell specification, it recommends a scope of SOC of 10% to 90%. The use of battery cells within this SOC window can effectively extend battery life.


    There are many Lithium Iron Phosphate battery suppliers, but Energie Panda provides you brand new grade A cells.
