【4X Lifespan & 2X Performance-price Ratio】SANFOU LiFePO4 battery's lifespan is 10 years, while lead-acid's is 3 years. 12.8V 50Ah lithium battery can reach 100% depth of discharge, while lead-acid only reaches 50%. Based on depth of discharge and service life, one SANFOU 12.8V 50Ah = two 12V 50 Ah lead-acid batteries, which means it costs 6 lead-acid batteries for 10 years, and the comprehensive cost is 2X than LiFePO4 batteries.
