High-capacity LiFePO4 batteries store power and run various appliances and devices across various settings. The voltage of Lithium-ion phosphate rechargeable batteries varies depending on the SOC. As the battery charges or discharges, the voltage increases. The higher the LiFePO4 battery voltage, the more increased capacity and energy stored.
Here are some basic definitions to enable you to understand LiFepo4 battery voltage better.
Nominal Voltage-
The battery delivers its best performance at the recommended level, 3.25V. This standard level is for monitoring the charging and discharging of the battery.Storage Voltage-
This is the ideal voltage in which the battery must be stored if not in use for a prolonged time. Storage voltage ensures good battery health and reduces capacity loss.Fully Charged Voltage-
It ranges at 3.65V and it is the maximum voltage for charging. Charging beyond this level causes irreparable battery damage.Discharge Voltage-
Discharge optimal voltage is 2.5V. A user should never discharge under this level. Exceeding the discharge limit damages the battery.Deep Discharge-
At this point, the voltage runs below the recommended level. Deep discharge renders the LiFePO4 batteries and may render them completely obsolete.The LiFePO4 voltage chart enables the users to understand the recommended charge levels for safe charging. Also, it acts as a reference point for gauging battery performance and identifying the state of charge for various batteries.
Here is a voltage chart illustrating the state of charge at various voltages.
Every lithium iron phosphate battery has a nominal voltage of 3.2V, with a charging voltage of 3.65V. The discharge cut-down voltage of LiFePO4 cells is 2.0V. Here is a 3.2V battery voltage chart.

LiFePO4 batteries have various voltage stages, namely: bulk, float, and equalize. During the bulk stage, the battery charges rapidly at a constant current up to a certain voltage. In the float stage, the battery maintains the voltage charge. This extends the battery's efficiency and extends its lifespan. The equalization stage balances the cells while ensuring uniform charging.
In simple terms, the cycles or the charge and discharge rates are the battery's charging patterns. These charging patterns are crucial for maintaining the health and durability of the battery. Therefore, you must observe proper and safe charging and discharging patterns. The state of charge indicates the capacity that can be discharged over the total battery capacity. The voltage increases when you charge the battery. The SOC of the battery is dependent on its charge.
Example: A 100Ah battery has a 30Ah capacity for discharging. Therefore, the SOC is 30%. If the battery charges to 100Ah and discharge 70Ah, then 30Ah remains.
