Why the Motor Controller Matters in Golf Carts
The motor controller functions as the “brain” of an electric golf cart. It interprets throttle input and precisely regulates how much power flows from the batteries to the motor. A failing controller can cause:
- Jerky acceleration
- Reduced top speed
- Weak hill-climbing ability
- Overheating issues
- Intermittent power loss
The Legavigy 48V 250A 1510-5201 addresses these issues by restoring stable current delivery and accurate throttle modulation.
Performance Benefits of the Legavigy 48V 250A Controller
