The most remarkable advantages of large format lithium iron phosphate (LiFePO4) compare with SLA are listed as below:
A. The cycle life of LiFePO4 is more than 1000 times.but the SLA is 300 times.
B. The Gravimetric energy density (Wh/kg) and volumetric energy density (Wh/L) of LiFePO4 is about 3-4 times of SLA.
C. But for the weight and Size comparison for the same capacity,the LiFePO4 is just 1/3 of SLA.
There are some other different specifications which suit for E-bicycles, E-tricycles, E-scooters, E-motorcycles, golf cars, commute cars, pedicabs, E-boats and etc.
