The 3.2V single cell LiFePO4 battery operates within specific voltage levels that are crucial for its performance and longevity. The nominal voltage is 3.2 volts, with a fully charged state reaching up to 3.65 volts and a fully discharged state at approximately 2.5 volts. These levels ensure optimal functionality in various applications.
Understanding Voltage Levels of LiFePO4 Batteries
LiFePO4 batteries are renowned for their stability, safety, and long cycle life. To maximize their effectiveness, it’s essential to understand the different voltage levels associated with these batteries:
Nominal Voltage
- The nominal voltage of a single LiFePO4 cell is 3.2 volts. This value is significant as it represents the average voltage during normal operation.
Fully Charged Voltage
- When fully charged, the voltage can rise to between 3.6 to 3.65 volts. It’s important to avoid exceeding this range to prevent overcharging, which can lead to battery damage.
Discharged Voltage
- The battery reaches a fully discharged state at around 2.5 volts. Discharging below this level can cause irreversible damage to the cell.
Voltage Levels by State of Charge (SoC)
The relationship between voltage and the state of charge is critical for users of LiFePO4 batteries. Below is a detailed chart illustrating the typical voltage levels corresponding to various states of charge:
| State of Charge (%) | Voltage (V) |
|---|---|
| 100% | 3.60 – 3.65 |
| 90% | 3.50 – 3.55 |
| 80% | 3.45 – 3.50 |
| 70% | 3.40 – 3.45 |
| 60% | 3.35 – 3.40 |
| 50% | 3.30 – 3.35 |
| 40% | 3.25 – 3.30 |
| 30% | 3.20 – 3.25 |
| 20% | 3.10 – 3.20 |
| 10% | 2.90 – 3.00 |
| 0% | 2.00 – 2.50 |
Storage Voltage Recommendations
For optimal longevity, it is recommended to store LiFePO4 batteries at a voltage between 3.2 and 3.3 volts per cell, which helps minimize self-discharge and maintain overall health.
