A 48V LiFePO4 battery is fully charged at 58.4 volts. This voltage is achieved when the battery cells, typically configured in series, reach their maximum charge level. Each LiFePO4 cell has a nominal voltage of 3.2V and can be charged up to approximately 3.65V per cell. For a 48V configuration, which consists of 16 cells in series, the total fully charged voltage is calculated as follows:
- Fully Charged Voltage: 16 cells×3.65 V cell=58.4 V
When discharging, the battery should not go below 40 volts to maintain optimal performance and longevity.
Summary of Key Voltages for a 48V LiFePO4 Battery:
- Fully Charged: 58.4 V
- Nominal Voltage: 48 V
- Fully Discharged: 40 V
This charging range ensures that the battery operates efficiently while maximizing its lifespan.
