Removing the speed limiter on an electric golf cart is a relatively simple process. First, locate the controller box under the seat or in the battery compartment of your cart. Inside this box you will find two small screws that need to be adjusted with a screwdriver. Turn both screws clockwise until they are completely tightened and then restart your cart. This should remove any speed limiters and allow you to reach higher speeds than before. Be sure to follow all safety precautions when driving at high speeds as well as local laws regarding maximum speed limits for electric carts in your area.
