TheEVE 280Ah LiFePO4 battery pack is a reliable energy source with a stable discharge voltage close to 12.8V. LiFePO4 cells lose capacity slowly and have a low self-discharge rate, which allows for a long charge. Fast charging restores almost 100% of the capacity in one hour. The service life of LiFePO4 batteries is two or more times longer than that of lead-acid batteries. The battery section has a rated capacity of 280Ah and AC resistance of ≤0 .25mΩ. The maximum long-term charge and discharge current is 1C, with a short-term maximum of up to 2C. It is recommended to keep the charge level between 10% and 90% for optimal performance.

Features.
LiFePO4 cells lose their capacity more slowly
LiFePO4 batteries have a lower self-discharge rate and can be discharged for a long time without significant consequences for their further operation
The discharge voltage and residual capacity of LiFePO4 batteries remain stable at different load currents
The discharge voltage remains close to 12.8 V until the battery is completely discharged
Fast charging with a current of 100% of the capacity, i.e. in 1 hour you can restore almost 100% of the capacity
The service life of LiFePO4 batteries is two or more times longer than that of lead-acid batteries
LiFePO4 batteries are lighter and smaller than lead-acid batteries, their weight can be 2-4 times less
