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 Voltage	Float Voltage	Inverter Cut-off Voltage
12V (4S)	14.5V	13.6V	10.7V ~ 12V
24V (8S)	29V	27.2V	21.4V ~ 24V
48V (16S)	58V	54.4V	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

	Absorption Voltage	Float Voltage	Low Voltage Disconnect
3.2V LiFePO4 cell	3.625V	3.4V	2.5V

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.
