Lead-acid batteries have been used for decades due to their reliability and low cost. LiFePO4 battery technology has advanced significantly in the last few years. They have a higher capacity, weight, operating temperature, and CO2 reduction than standard lead batteries.
LiFePO4 is quickly becoming an industry standard. While LiFePO4 batteries are more expensive than lead-acid in the beginning, they have a longer life span that makes them a good financial choice.
