The optimal charge voltage for a 36V LiFePO4 battery ranges between 43.6V (3.65V per cell) and 44.4V (3.7V per cell), balancing longevity and capacity. Charging beyond 44.4V risks premature degradation, while undercharging reduces usable capacity.… Optimal Charge Voltage for LiFePO4 36V Batteries: A Comprehensive Guide
