Electric, or battery powered, golf carts use several batteries wired together in sequence to produce power. The amount of power is one factor which determines how fast an electric golf cart will go. With the popularity of privately owned golf carts there are any number of after market upgrades which are designed to increase the carts power and speed. However, there are several things which may be done to existing electric carts which do not require an upgrade and result in a faster cart.
Wash the golf cart thoroughly to remove dirt and debris. Use a soapy solution and a cloth (and scrub brush, if necessary) to clean the entire cart--including the wheels and undercarriage. Dirt and mud may interfere with the normal operation of a cart and result in slower speeds.
Remove the seat of the golf cart and inspect the batteries. Make sure all cables are securely tightened and that there is no corrosion on the terminals which may interfere with charging or power distribution. Use a bristle brush to remove any corrosion.
Open the fill caps of the batteries to check the water level. Add distilled water as necessary to fill the battery cells to the manufacturer's recommended levels. Low water level may prevent batteries from fully charging.
Inspect the gas pedal and linkage to determine if there is anything blocking or preventing the pedal from being fully depressed. Use an adjustable wrench to adjust the pedal, if possible, and tighten any loose connections.
Check the tire pressure using a tire gauge. Make sure that the tires are properly inflated to manufacturers specifications. Use a tire pump to add air as needed. Low tire pressure can lower the speed of electric golf carts.
Charge the golf cart using the charging unit supplied with the cart. Make sure to allow the batteries to fully charge. Turn off all devices such as lights and radios which may drain the batteries during the charging process.
