Charged voltage (also called full-charge voltage) is the highest voltage a cell reaches when fully charged. Exceeding this voltage can damage the battery and reduce its lifespan, so proper charging is crucial. For a 3S Li-ion battery pack, the fully charged voltage would be 12.6V (4.2V × 3). Why Does Charged Voltage Matter?
Charge Voltage – The voltage that the battery is charged to when charged to full capacity. Charging schemes generally consist of a constant current charging until the battery voltage reaching the charge voltage, then constant voltage charging, allowing the charge current to taper until it is very small.
Different system voltages follow the same principle but scale upward: For example, a 48V LiFePO4 battery full charge voltage is typically 58.4V, while nominal voltage sits near 51.2V. These values are essential for solar inverters, EV chargers, and energy storage systems.
In the discharge cycle, initially, the voltage will be 4.2V. When we continue to utilize the battery, the voltage may drop to the nominal rate of 3.7V. When used more, the voltage could drop to 3.0V and will eventually reach the cell's limits. Throughout charging, the opposite will happen.
A fully charged battery, for example, could be approximately 4.2 volts per cell while a fully discharged battery could be 3.0 volts per cell. Impact of Temperature: Temperature is one of the important

Float Voltage – The voltage at which the battery is maintained after being charge to 100 percent SOC to maintain that capacity by compensating for self-discharge of the battery.
