LiFePO4 (lithium iron phosphate) batteries outperform lead-acid batteries in energy density, lifespan, and efficiency. They provide 3-5x more cycles (2,000–5,000 cycles), faster charging, and 95% usable capacity. Unlike lead-acid, they’re maintenance-free, lightweight, and operate efficiently… What Are the Best LiFePO4 Batteries for Inverters and Fishing Boats?
