What is the Best Voltage for LiFePO4?

The best voltage for LiFePO4 (Lithium Iron Phosphate) batteries is typically 3.2 to 3.3 volts per cell. For a complete battery pack, the nominal voltage is usually around 12.8V for a 4-cell configuration. This voltage range ensures optimal performance, safety, and longevity of the battery.

Understanding Voltage in LiFePO4 Batteries

Voltage is a critical factor in determining the performance and efficiency of LiFePO4 batteries. Understanding the optimal voltage levels can help users maximize battery life and ensure safe operation.

Key Voltage Characteristics:

  1. Nominal Voltage:
    • The nominal voltage of a single LiFePO4 cell is approximately 3.2V to 3.3V. This is the average voltage during discharge and represents the typical operating range.
  2. Fully Charged Voltage:
    • When fully charged, a LiFePO4 cell reaches about 3.6V to 3.65V. Charging beyond this limit can lead to overheating and potential damage.
  3. Discharge Cutoff Voltage:
    • The discharge cutoff voltage for LiFePO4 batteries is typically set at around 2.5V to 2.8V per cell. Discharging below this threshold can result in irreversible damage to the battery.
