The Power System


When we talk about a 48-volt golf cart, we’re referring to the total voltage of the batteries that power the cart. Golf carts typically use between 4 and 6 batteries, and the voltage of each battery contributes to the total voltage of the cart. It’s crucial to understand your golf cart’s power system, as it influences the performance, maintenance, and cost of your vehicle.

Most golf carts are electric, powered by a series of batteries. However, some models use gasoline. The voltage of the batteries in these carts can vary. You can usually find the voltage of a battery indicated on its label, but if it’s not, you can calculate it by counting the number of holes on the battery. Each hole represents 2 volts, so a battery with 3 holes, for example, is a 6-volt battery.

The most common total voltages for golf carts are 36 volts and 48 volts. Recently, the 48-volt golf cart has become more popular. A 48-volt golf cart typically uses eight 6-volt batteries to achieve this total voltage.

Gasoline-powered golf carts, on the other hand, can operate with a single 12-volt battery. Some newer models even use four 12-volt batteries. The perks of gasoline carts include:

  • Can run continuously as long as there’s fuel in the tank.
  • More horsepower enabling them to handle steep hills and heavy loads with ease
  • However they also produce emissions and are noisier

Golf carts differ from everyday cars in several ways. For instance, the engine doesn’t start when you turn the key, but rather when you press the accelerator. This design results in less noise and lower energy or fuel consumption. Maintaining your golf cart’s batteries involves regular cleaning of the terminals and inspections to ensure there are no acid or liquid spills.

Importance of Wiring Lights

While golf carts may not come with lights as standard, adding them can significantly enhance the safety, legality, and convenience of your vehicle.

Whether you’re driving on public roads or navigating your property in the dark, lights are a crucial addition to your golf cart. Here’s why:

Compliance with State Laws

If you’ve some basic knowledge of car maintenance, by tracking a few easy and simple rules, you can easily equip your vehicle with all the lights you want to be able to legally drive them on the streets.

If you plan to drive your golf cart on public roads, it’s essential to know that most state laws require vehicles to be equipped with headlights, brake lights, and turn signals. This isn’t just a legal requirement—it’s a safety measure to ensure visibility on the roads.

With some basic knowledge of car maintenance and a suitable light kit, you can install these lights yourself, making your golf cart street-legal.

Improved Visibility

Driving your golf cart in the evening or at night can be challenging without proper lighting. Streetlights can only do so much, and they certainly can’t illuminate every corner of your path.

Installing headlights and sidelights on your golf cart can help you navigate dark areas more safely, reducing the risk of accidents with other vehicles or animals. Plus, your lights will alert others to your presence, ensuring they can make way for you.

Vehicle Communication

Lights on a vehicle do more than just illuminate the path ahead—they also serve as a form of communication with other drivers. Brake lights and turn signals, for instance, silently convey your intentions, helping to prevent collisions.

A red brake light or a flashing turn signal is a universal language understood by drivers everywhere, making them essential for safe driving.
