Can I Put 4 12-Volt Batteries in My 48-Volt Golf Cart?

In this article, we will explore whether it is possible to use four 12-volt batteries in a 48-volt golf cart system.


Golf carts have become a popular means of transportation for golfers and recreational users alike. These electric vehicles rely on batteries to provide the necessary power for a smooth ride. When it comes to upgrading or replacing the batteries in a golf cart, questions arise about voltage compatibility. In this article, we will explore whether it is possible to use four 12-volt batteries in a 48-volt golf cart system.

Understanding Golf Cart Batteries

Before delving into the compatibility of batteries, it's essential to understand the basics. Most golf carts operate on either a 36-volt or 48-volt electrical system. These systems are typically powered by a series of six 6-volt batteries or four 12-volt batteries, respectively. The voltage rating determines the overall power output and performance of the golf cart.

Compatibility of Four 12-Volt Batteries

While it may seem logical to assume that four 12-volt batteries can be combined to create a 48-volt system, unfortunately, it's not that straightforward. Golf cart systems are designed to operate at specific voltage levels, and deviating from those specifications can lead to various issues.

Wiring and Connection Challenges

One major hurdle in using four 12-volt batteries is the discrepancy in the number of batteries required. A 48-volt system typically requires six 8-volt or four 12-volt batteries. Attempting to connect four 12-volt batteries may pose challenges in terms of wiring and connection options. The number of battery compartments and available space may not align with this configuration, making it difficult to achieve a secure and reliable connection.

Battery Life and Performance

Using four 12-volt batteries to achieve a 48-volt system can impact the overall battery life and performance of your golf cart. Battery banks are designed to work in unison, and mixing different voltage batteries can lead to imbalances within the system. This imbalance can result in uneven discharge rates and reduced battery life.

Controller and Motor Compatibility

Golf carts with 48-volt systems are equipped with controllers and motors specifically designed to handle that voltage. Introducing four 12-volt batteries to create a 48-volt system may overload these components, potentially causing damage. Compatibility issues between the battery bank and other electrical components can result in poor performance, reduced range, and increased wear and tear on the cart's electrical system.

Alternative Solutions:

Instead of attempting to create a 48-volt system with four 12-volt batteries, consider the following alternatives:

Replace with Proper Voltage Batteries

To ensure optimal performance and longevity, it is recommended to replace your golf cart's batteries with the correct voltage rating. If your cart requires a 48-volt system, invest in four 12-volt batteries specifically designed for golf cart applications.

Consult a Professional

If you're unsure about battery compatibility or any other electrical modifications, it's always wise to consult a professional. An expert in golf cart systems can provide guidance on the best battery options and ensure a safe and efficient installation.


While it may be tempting to use four 12-volt batteries to create a 48-volt system in your golf cart, it is not recommended due to various compatibility issues. Golf carts are designed to operate within specific voltage ranges, and deviating from these specifications can lead to performance issues and potential damage to the cart's electrical components. To ensure optimal performance and longevity, it's best to use the recommended battery configuration or consult a professional for guidance.
