How Many LiFePO4 Batteries Can Be Connected in Series?

You can typically connect up to 4 LiFePO4 batteries in series to achieve a higher voltage while maintaining the same capacity (Ah). However, it’s crucial to ensure that all batteries are of the same type, capacity, and state of charge to avoid imbalances that can lead to reduced performance or damage.

Understanding Series Connections for LiFePO4 Batteries

Connecting batteries in series is a common practice to increase voltage for applications requiring higher power. Understanding how many LiFePO4 batteries can be connected in series is essential for optimizing performance and ensuring safety.

Key Considerations for Connecting Batteries in Series

  1. Voltage Requirements: Each LiFePO4 cell has a nominal voltage of 3.2V. Therefore, connecting multiple cells in series will increase the total voltage. For example:
    • 2 batteries: 6.4V
    • 3 batteries: 9.6V
    • 4 batteries: 12.8V
  2. Capacity Consistency: When connecting batteries in series, the overall capacity (Ah) remains the same as that of a single battery. It is crucial to use batteries with the same capacity to ensure balanced discharge and charge cycles.
  3. Battery Management System (BMS): A BMS is highly recommended when connecting multiple LiFePO4 batteries in series. It helps monitor individual cell voltages and balances them during charging and discharging, preventing overcharging or deep discharging.
Number of Batteries Total Voltage Capacity (Ah) Recommended Action
1 3.2V 100Ah Use as standalone
2 6.4V 100Ah Ensure same capacity
3 9.6V 100Ah Use BMS for safety
4 12.8V 100Ah Monitor individual cell voltages
