The LiFePO4 voltage chart enables users to understand the recommended charge levels for safe charging and acts as a reference point for battery health. Here is a table showing the state of charge (SoC) vs voltage for a typical 12V LiFePO4 battery: A 12V LiFePO4 battery is typically composed of four 3.2V cells connected in series.
Here is a LiFePO4 Lithium battery state of charge chart based on voltage for 12V, 24V, and 48V LiFePO4 batteries. Individual LiFePO4 cells typically have a 3.2V nominal voltage. The cells are fully charged at 3.65V, and at 2.5V, they become fully discharged. Here's a 3.2V battery voltage chart:
The lithium iron phosphate (LiFePO4) battery voltage chart represents the state of charge (usually in percentage) of 1 cell based on different voltages, like 12V, 24V, and 48V. Here is a LiFePO4 Lithium battery state of charge chart based on voltage for 12V, 24V, and 48V LiFePO4 batteries.
A fully charged cell reaches approximately 3.65V. You should pay attention to both charge voltage and discharge voltage. The charge voltage for LiFePO4 cells generally lies between 3.55V and 3.70V, while the low voltage cutoff is around 2.5V per cell. Remember to reference the chart for specific configurations like 12V, 24V, and 48V setups.
You can estimate the charge level with specific voltage readings. For instance, a voltage of 12.6V to 13.2V typically indicates about 100% charge for a 12V LiFePO4 battery. As the battery discharges, voltages drop. At 11.4V, the battery is around 50% charged. When the voltage reaches 10V, it is time to recharge.
For instance, a 12V LiFePO4 battery will have a higher capacity than a 6V battery of the same size. Therefore, it is crucial to choose the right voltage rating based on the project’s power requirements. LiFePO4 batteries require a specific charging voltage and current for optimal performance.
