The new range of ePropulsion batteries have a long lifespan. Even for commercial customers using the batteries all day everyday we expect a life of 3000 cycles to 80% of the original capacity. The LiFePO4 batteries are the safest type of Lithium batteries as they will not overheat, and even if punctured they will not catch on fire. The cathode material in LiFePO4 batteries is not hazardous and so poses no negative health hazards or environmental hazards.
