EverExceed LiFePO₄ (Lithium Iron Phosphate) batteries are widely recognized for their stable performance, long cycle life, and superior safety. Their charging and discharging characteristics make them especially suitable for demanding applications such as telecom, UPS, and energy storage systems.

1. Charging Process (CC-CV Method)

EverExceed LiFePO₄ batteries adopt the industry-standard Constant Current – Constant Voltage (CC-CV) charging strategy.

• Constant Current (CC) Stage

  • Charging begins with a large constant current (e.g., 0.5C or 1C, where C represents the battery’s capacity).

  • During this stage, the battery voltage gradually rises until it reaches the cut-off voltage (typically 3.65V per cell).

  • Around 70–80% of the total capacity is charged in this stage, making it fast and efficient.

• Constant Voltage (CV) Stage

  • Once the voltage reaches 3.65V, the charger holds the voltage steady while the charging current decreases exponentially.

  • When the current drops to a very low value (such as 0.05C or 0.02C), the battery is considered fully charged.

  • This stage prevents overcharging and extends battery lifespan.
