A new green energy solution for mankind. Compared with SLA batteries, LiFePO4 batteries have significantly more advantages. Up to 95% nominal capacity and only 1/3 the weight of a lead-acid battery, while SLA batteries are typically limited to 50%, are easy to move and have more energy delivery. Up to 90% capacity for more than 4000 cycles under recommended conditions. LiFePO4 batteries support wide application such as off-grid life, RV, fish finder, scooter, industrial, hiking, emergency power backup, etc.
