If you are looking to increase the overall efficiency of your cart, a Navitas AC Conversion Kit can help. It will give your cart improvements in range, battery life, and speed/torque performance.
Most accessories that require electricity to operate use an input voltage of 12V DC. Unless you have a direct 12V battery connection (gas cart or electric cart with 12V batteries), then you need a way to reduce the carts' overall voltage to 12V (in order to prevent damage to these electrical components). To accomplish this, you can use a voltage converter or a voltage reducer.
