Can You Upgrade a 36V Golf Cart to 48V?
Yes, it is possible to upgrade a 36V golf cart to 48V, but it involves several critical considerations and modifications. This upgrade is not a simple plug-and-play operation; it requires careful planning and execution to ensure that all components are compatible and the cart operates safely and efficiently.
Components That Need Upgrading
Motor, controller, wiring, and batteries typically require replacement for a successful upgrade.
- Batteries: You will need to replace the existing 36V batteries with 48V batteries. Typically, a 48V golf cart uses either six 8V batteries or four 12V batteries.
- Motor: The golf cart’s motor must be capable of handling the increased voltage. A motor designed for 36V may not efficiently handle the higher voltage and could be damaged if used with a 48V system.
- Controller: The cart’s controller regulates the flow of electricity from the batteries to the motor. Upgrading to a 48V system requires a compatible 48V controller to manage the increased voltage safely.
- Wiring: Upgrading the voltage will necessitate new wiring that can handle the increased power output. Ensure all wiring and connectors are rated for 48V to avoid potential overheating or electrical failure.
- Charger: A new charger that supports 48V is essential for charging the upgraded battery system. Using a 36V charger with a 48V battery pack could result in insufficient charging and battery damage.
Potential Issues with Upgrading
Expect compatibility problems, increased strain on other parts, and high overall costs.

- Motor Compatibility: As previously mentioned, a 36V motor might not handle 48V well. Overvolting can lead to overheating and premature failure.
- Battery Life: Different voltages affect the performance and lifespan of batteries. A 48V system may have different charging and discharging characteristics compared to a 36V system.
- Controller Stress: A 36V controller may struggle to manage the increased voltage, leading to potential malfunctions or damage.
How Fast Does a 48V Golf Cart Go?
A 48V golf cart typically goes 14 to 20 mph, depending on the specific model and setup.
The speed of a 48V golf cart can vary based on several factors:
- Motor Type: The type of motor installed plays a significant role in speed. High-performance motors can push the cart to higher speeds.
- Battery Size: Larger batteries with higher amp-hour ratings (Ah) can contribute to better performance and speed.
- Terrain: Flat terrain allows for higher speeds compared to hilly or uneven surfaces. On flat terrain, a 48V golf cart typically reaches speeds of up to 20 mph. With larger batteries and under optimal conditions, speeds can extend to 25 mph.
Cost of Upgrading a 36V Golf Cart to 48V
The cost of converting a 36V golf cart to 48V varies based on the components used and the complexity of the upgrade. On average, the conversion cost ranges between $500 to $2,000. This includes expenses for new batteries, a compatible motor, controller, wiring, and charger.
How to Identify a 36V vs. 48V Golf Cart
To determine the voltage of your golf cart, you can check the number of batteries and their voltage ratings:
- 36V Golf Cart: Typically uses six 6V batteries or three 12V batteries.
- 48V Golf Cart: Commonly uses six 8V batteries or four 12V batteries.
Count the water fill caps on the batteries—six for 6V (totaling 36V), or six for 8V (totaling 48V), or four for 12V (totaling 48V).
Do They Still Make 36V Golf Carts?
Yes, 36V golf carts are still manufactured and available. Major brands like ClubCar, EZGO, and Yamaha continue to produce both 36V and 48V models. They offer a range of options to suit various needs and preferences.
Can You Use 3 12V Batteries in a 36V Golf Cart?
Yes, three 12V batteries can be used in a 36V golf cart. Connecting them in series will provide the required voltage. Ensure the batteries are of high quality and properly connected to avoid electrical issues.
How Long Does a 48V Golf Cart Battery Last?
On average, 48V golf cart batteries last between four to six years. Proper maintenance, including regular charging and water refilling, can extend their lifespan.
Should I Leave My Golf Cart Plugged in All the Time?
Keeping your golf cart plugged in is generally advisable. This practice helps to maintain the battery’s charge and prevents the gradual loss of capacity that can occur if the battery is left in a discharged state for extended periods.
How to Make Your 36-Volt Golf Cart Faster
If you’re looking to boost the performance of your 36-volt golf cart, consider the following enhancements:
- Upgrade the Speed Limiter: Adjusting or removing the speed limiter can increase top speed.
- High-Performance Batteries: Investing in high-performance batteries can provide better power and speed.
- Optimize Motor and Controller: Upgrading to a high-performance motor and controller can significantly boost speed.
- Adjust Gear Ratios: Altering gear ratios can improve acceleration and top speed.
- Enhance Aerodynamics: Reducing drag by improving aerodynamics can contribute to better performance.
Can You Put Lithium Batteries in a 36-Volt Golf Cart?
Lithium batteries can be used in a 36V golf cart. They offer advantages such as longer lifespan, lighter weight, and faster charging. Ensure that the voltage of the lithium batteries matches the requirements of your golf cart.
