36 Volt EZ Go Golf Cart Battery Wiring Diagram

Hello readers, welcome to our comprehensive guide on the 36 volt EZ Go golf cart battery wiring diagram. In this article, we will provide you with detailed information on how to properly wire the battery system of your golf cart. Whether you are a beginner or an experienced golfer, understanding the wiring diagram is crucial for maintaining the performance and longevity of your golf cart. So, let’s dive in!

1. Understanding the 36 Volt Battery System

Before we get into the wiring diagram, let’s first understand the basics of a 36 volt battery system. A typical EZ Go golf cart uses six 6-volt batteries to power a 36-volt electric motor. These batteries are connected in a series to achieve the desired voltage. The positive terminal of one battery is connected to the negative terminal of the next battery, and so on, until all six batteries are connected in a chain.

The final positive and negative terminals of the battery chain are then connected to the respective terminals of the golf cart’s motor controller. This completes the circuit and allows the electric motor to run.

2. Wiring the Batteries

The first step in wiring your 36 volt EZ Go golf cart battery system is to gather all the necessary tools and materials. You will need a set of wrenches, wire cutters, wire strippers, electrical tape, and a battery wiring diagram specific to your golf cart model.

Next, carefully remove the old battery cables from the batteries, making sure to note their positions for reference. Clean the battery terminals and cable connectors with a wire brush to ensure good conductivity.

Refer to the wiring diagram and begin connecting the battery cables according to the specified configuration. Start by connecting the positive terminal of the first battery to the negative terminal of the second battery using a battery cable. Repeat this process until all six batteries are connected in a series.

Finally, connect the positive terminal of the last battery in the series to the positive terminal of the motor controller, and connect the negative terminal of the first battery to the negative terminal of the motor controller. Ensure all connections are tight and secure.

3. Benefits of Proper Wiring

Properly wiring your 36 volt EZ Go golf cart battery system offers several benefits. Firstly, it ensures efficient power distribution throughout the system, maximizing the performance and range of your golf cart. Secondly, it reduces the risk of electrical faults and short circuits, which can cause damage to the batteries or other components. Lastly, it simplifies troubleshooting and maintenance, as a well-wired system is easier to inspect and repair.

4. Common Wiring Mistakes to Avoid

While wiring your golf cart battery system, it is important to avoid common mistakes that can lead to issues in the long run. One common mistake is connecting the batteries in the wrong order, which can reverse the polarity and damage the motor controller. Another mistake is using incorrect wire sizes, which can result in voltage drop and reduced performance. Always refer to the wiring diagram and follow the manufacturer’s guidelines to avoid these mistakes.

5. Alternative Wiring Options

Although the standard series wiring is the most common method for connecting the batteries in a 36 volt EZ Go golf cart, there are alternative wiring options available. One alternative is the parallel wiring, where each battery’s positive terminal is connected to a common positive terminal, and each negative terminal is connected to a common negative terminal. This configuration allows for increased capacity and longer runtime, but it requires additional wiring and a compatible motor controller.

7. Frequently Asked Questions

Q: Can I use different battery brands or capacities in my 36 volt EZ Go golf cart?

A: It is recommended to use batteries of the same brand, type, and capacity in your golf cart. Mixing different brands or capacities can lead to imbalanced charging and discharging, resulting in reduced performance and battery lifespan.

Q: How often should I check the battery wiring of my golf cart?

A: It is advisable to inspect the battery wiring at least once a year or whenever you notice any decrease in performance. Regular maintenance and cleaning of the battery terminals can prevent corrosion and ensure proper electrical connections.

Q: Can I upgrade my 36 volt EZ Go golf cart to a higher voltage system?

A: Upgrading to a higher voltage system requires replacing the motor controller, charger, and other components. It is recommended to consult a professional or the golf cart manufacturer for guidance on the compatibility and feasibility of such an upgrade.


In conclusion, understanding and properly wiring the battery system of your 36 volt EZ Go golf cart is crucial for optimal performance and longevity. By following the wiring diagram and avoiding common mistakes, you can ensure efficient power distribution and reduce the risk of electrical faults. Regular maintenance and inspection are also essential to keep your golf cart in top shape. If you have any further questions or need assistance, feel free to reach out to our team of experts.
