Switching from lead-acid to LiFePO4 typically reduces battery weight by 70%. This significantly lowers the "unsprung weight" of the vehicle, extending the life of tires, brakes, and suspension components.
In personal mobility devices like power chairs, weight directly impacts efficiency. A standard lead-acid pair can weigh over 60 lbs, whereas a WVMILFE lithium solution weighs approximately 18 lbs.
Lower mass means the motor requires less starting torque, reducing heat in the controller. It also decreases the kinetic energy that the braking system must dissipate, leading to shorter stopping distances and less brake pad wear. For users, the lightweight nature of lithium significantly improves safety during loading and unloading.
