In this comprehensive article, we will explore the feasibility, benefits, and drawbacks of using four 12V batteries in a 48-volt golf cart, and provide valuable insights to help you make an informed decision. We’ll also look at how these systems work, what kind of wiring is required, and the practical considerations for modifying your golf cart.
Understanding the 12V Battery System
Before we dive into the specifics of using four 12V batteries in a 48-volt golf cart, let’s first understand how a 12-volt battery works in a golf cart system. A golf cart typically operates on a 48-volt battery bank, but each individual battery within that system usually produces a voltage of 6, 8, or 12 volts. By connecting multiple batteries together in series, the voltage can be increased to the desired level.
A 12V battery is widely used in many applications, including vehicles, boats, and other battery-powered devices. In a golf cart, if you want to maintain a 48-volt system, the 12V batteries must be connected in a series configuration.
How Does a 12V Battery Work in a Golf Cart?
The 12V battery in a golf cart functions similarly to how it operates in other applications. It stores and supplies electrical energy to the cart’s motor, enabling it to operate. However, to achieve the necessary voltage for a golf cart, you need to connect four of these batteries in series, each contributing its voltage to the overall system.
When batteries are connected in series, the voltage is additive, meaning the voltage of each battery is summed together. Therefore, four 12-volt batteries will provide a total of 48 volts (12V + 12V + 12V + 12V = 48V), which is what is required to power most golf carts effectively.

The Pros and Cons of Using Four 12V Batteries
When considering whether to use four 12V batteries in a 48-volt golf cart, there are several factors to weigh. Below, we examine the pros and cons of this configuration to help you understand its advantages and disadvantages.
Advantages of Using Four 12V Batteries
1. Easier to Find: One of the main benefits of using 12V batteries is that they are commonly available and easy to find. Many retailers stock them, and they are often less expensive than other types of golf cart batteries, such as 6V or 8V options. This makes it convenient if you need a replacement or want to upgrade your system.
2. Simpler to Handle: 12V batteries tend to be smaller and lighter than their larger counterparts, such as 6V or 8V batteries. This can make installation and maintenance easier, especially for individuals who might not have the technical expertise to handle larger batteries.
3. Flexible Configuration: By using 12V batteries, you have greater flexibility in configuring the battery system. You can use four 12V batteries to create a 48V system or opt for a different number of batteries depending on your desired voltage level.
Disadvantages of Using Four 12V Batteries
1. Reduced Overall Battery Life: When you use four 12V batteries in a 48-volt configuration, the overall lifespan of your battery bank can be reduced compared to using higher-voltage batteries. This is because each individual 12V battery has a shorter cycle life than larger batteries.
2. Increased Maintenance: Having more batteries in your system means more points of failure. This can lead to increased maintenance and the need for more frequent checks to ensure that each battery is functioning properly.
3. Potential for Imbalance: If the batteries are not of equal age or charge state, they can become unbalanced, which may result in some batteries wearing out faster than others. This can reduce the overall efficiency and lifespan of your battery system.
How to Wire Four 12V Batteries in Series for 48V
To use four 12V batteries in a 48-volt golf cart, you need to connect them in series. Wiring the batteries correctly is essential to ensure that they work properly and provide the necessary voltage for your golf cart.
Step-by-Step Guide to Wiring Four 12V Batteries in Series
1. Identify the Terminals: Each 12V battery has two terminals: a positive (+) and a negative (-). You need to connect the positive terminal of one battery to the negative terminal of the next battery in the series.
2. Connect the First Two Batteries: Start by connecting the positive terminal of the first 12V battery to the negative terminal of the second 12V battery. This creates the first series connection.
3. Repeat the Process: Continue connecting the positive terminal of the second battery to the negative terminal of the third, and so on, until all four batteries are connected.
4. Final Connections: Once all four batteries are connected, the remaining free positive terminal of the fourth battery will be connected to your golf cart’s motor. The negative terminal of the first battery should be connected to the cart’s frame.
Important Considerations When Wiring Batteries
Battery Condition: Ensure that all four 12V batteries are of the same brand, model, and age. Mixing different types of batteries can lead to unbalanced charge cycles and reduce the performance of your system.
Proper Sizing of Cables: Use appropriately sized cables to handle the current flowing through the battery system. Under-sized cables can cause voltage drops and even lead to overheating.
Fuse Protection: Always include a fuse in the system to protect against shorts and other electrical faults.
Can You Use Four 12V Batteries Instead of 6V or 8V Batteries?
While using four 12V batteries to create a 48V system is possible, some golf carts use 6V or 8V batteries instead. These batteries are often preferred because they are designed specifically for use in golf carts, and their larger size allows them to store more energy.
Comparison of Battery Types
12V Batteries: Easier to find, simpler to handle, and often less expensive, but they may have a shorter lifespan and require more maintenance.
6V Batteries: Designed specifically for golf carts, they have a longer lifespan and greater efficiency but are typically larger and heavier.
8V Batteries: Offer a good middle ground between 12V and 6V batteries, providing a balance of performance and battery life.
While using 12V batteries is viable, for those seeking longer-term performance and fewer maintenance requirements, 6V or 8V batteries might be a better option.

Is It Worth Using Four 12V Batteries?
In conclusion, it is possible to use four 12V batteries in a 48-volt golf cart, but it comes with both advantages and challenges. The key benefits are easier availability and flexibility, while the drawbacks involve potential for reduced battery life, increased maintenance, and the need for careful wiring. Whether or not it’s worth using four 12V batteries depends on your specific needs, budget, and how much time you're willing to invest in maintaining the system.
For many golfers or individuals looking for a cost-effective way to power their carts, four 12V batteries may be an excellent choice. However, for those who need longer-lasting, more durable systems, exploring alternatives like 6V or 8V batteries may be a more prudent decision.
As always, whether you opt for 12V batteries or another configuration, make sure to follow proper wiring procedures and maintain your batteries regularly to ensure your golf cart remains functional and efficient for years to come.
By keeping these considerations in mind, you can make an informed decision about the best battery configuration for your 48-volt golf cart. Whether you choose four 12V batteries or another solution, proper maintenance and careful setup will ensure that your golf cart delivers optimal performance for your needs.
