Lithium iron phosphate battery, also known as LiFePO4 battery, is a new green energy solution for the mankind. Compared with SLA batteries, LiFePO4 has more prominent advantages. While SLA batteries can usually only deliver 50% of its rated capacity, LiFePO4 batteries are capable of delivering up to 95% capacity at only 1/3 of the weight of a lead-acid battery and with more than 4000 cycle times. It is widely used to power up off-grid appliance, RVs, fishing boats, camping, scooters, and industry, etc.
