Unlike lead-acid batteries, which suffer from low energy density and frequent recharging, the LiFePO4 battery delivers 460Ah capacity and 95%+ efficiency, providing 2-3x longer runtime per charge and reducing downtime.
Lead-acid batteries typically last 300-500 cycles before capacity drops significantly. Our LiFePO4 battery achieves 3,000+ cycles at 80% depth of discharge (DoD), offering 6-10x longer lifespan and lower replacement costs.
Lead-acid batteries require 8-12 hours to charge and regular water top-ups/equalization. This LiFePO4 battery supports 1-2 hour fast charging and is 100% maintenance-free, eliminating downtime and labor costs.
Lead-acid batteries lose 50%+ capacity below 0℃ and risk freezing. With an optional -20℃ heating function and stable discharge voltage, the LiFePO4 battery ensures reliable operation in freezing environments, unlike lead-acid alternatives.
