A new green energy solution for humanity. Compared to SLA batteries, LiFePO4 has 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 deliver more energy. Up to 90% capacity for more than 4000 cycles under recommended conditions. Support wide application such as off-grid, RV, fish finder, scooter, industrial, hiking, emergency power backup, etc.
