What voltage is a 48V LiFePO4 full charge?

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 Voltage16 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.
