Lifepo4 battery advantage :
LiFePO4 battery is the top energy choice for HEV, EV, UPS, electric tools and electric power storage system,as it is safe, environment-friendly and powerful with long cycle life and no memory effect.
Great cyclelife :
Lithium Iron Phosphate technology is that which allows the greatest number of charge / discharge cycles. That is why this technology is mainly adopted in Solar and wind Energy Storage , stationary energy storage systems (self-consumption, Off-Grid, UPS, etc.) for applications requiring long life.
The actual number of cycles that can be performed depends on several factors: Pevel of power in C-Rate Depth of Discharge (DOD) Operational environment : temperature, humidity, etc.
In standard environment, and for 1C cycles, we can get from the chart the below life cycle estimation for LFP2000 cycles at 100% DoD: 3000 cycles at 80% DOD 8000 cycles at 55% DOD It should be noted that following the number of completed cycle, the batteries still have a nominal capacity > 80% of the original capacity.
