Compared with lead-acid battery, the LiFePO4 battery has higher capacity, lighter and much better.
It should be noted that the cell would be possible to be at a over-discharged state by its self-discharge characteristics in case the cell is not used for long time.
In order to prevent over-discharging, the cell shall be charged periodically to maintain between 6V and 6.8V. Over-discharging may causes loss of cell performance, characteristics, or battery functions.
