LiFePO4 Battery Advantages
- Superior safety features and environmental friendliness
- No memory effect for flexible charging patterns
- Extended cycle life for long-term reliability
- Ideal for HEV, EV, UPS, electric tools, and power storage systems
Extended Cycle Life Performance
Lithium Iron Phosphate technology delivers exceptional charge/discharge cycle performance, making it ideal for solar and wind energy storage, off-grid systems, UPS applications, and stationary energy storage requiring long operational life.
Cycle life estimates under standard conditions (1C cycles):
- 2000 cycles at 100% Depth of Discharge (DOD)
- 3000 cycles at 80% Depth of Discharge (DOD)
- 8000 cycles at 55% Depth of Discharge (DOD)
After completing these cycles, batteries maintain >80% of original nominal capacity.
