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
|Inverter Cut-off Voltage
|10.7V ~ 12V
|21.4V ~ 24V
|42.8V ~ 48V
If you want to test battery cell‘s capacity, please test it as the following charge profile.
Charge Profile for Individual LiFePO4 battery cell
|Low Voltage Disconnect
|3.2V LiFePO4 cell
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.
