A key decision when selecting an electric golf cart is choosing between a 48v and a 36v model. But which one is better for your needs? Let’s take a closer look at these two different voltage electric golf carts to help you make an informed decision.
The “V” after the number stands for “volts,” which is the unit of voltage. Simply put, voltage is the difference in potential between the two poles (positive and negative) of a battery. The negative terminal of a battery is also called the anode, where there is an excess of electrons; the positive terminal is called the cathode, where there is a relative shortage of electrons. When the circuit is closed, electrons flow from the negative pole to the positive pole, generating electricity in the process to drive the electric golf cart. When the number of electrons at the two poles equalizes, the battery is depleted and needs to be recharged.
The greater the potential difference between the two poles, the higher the voltage. The level of voltage directly determines the strength of the current. What does this mean for golf carts? Simply put, higher voltage translates into more power. So, a 48V cart has more power than a 36V one.
Determining the voltage of your electric golf buggy isn’t really that complicated; it just takes a few simple steps:
A common 36-volt golf cart usually has six 6-volt batteries, while a 48v cart usually has six 8-volt batteries, each with four water fill holes. It is important to note that almost all major manufacturers have phased out 36-volt golf carts.
The 48-volt system has more low-torque output. The difference is noticeable when you start to accelerate. Simply put, a 48-volt cart feels like it puts more pep in your step, and it starts and picks up a little more quickly than a 36-volt cart. For example, starting from a standstill on an incline, a 48V wheelbarrow can handle it more easily and climb quickly, while a 36V wheelbarrow may struggle a bit.
A 48v system draws less current while providing the same amount of power, which means it is more efficient in its energy utilization. Assuming the same load, motor power, etc., a 48v wheelbarrow will have a longer range on a single charge. Because the lower current draw slows down the depletion of battery power, you can travel longer distances, so you don’t have to worry about running out of power as often on the course.
If you drive in areas that are hilly or have poor road conditions, a 48V cart is a better choice. Its power will help you navigate rolling hills and rough roads with ease, allowing you to get to your destination without any problems. On the other hand, if you primarily drive in flat, dry areas with level surfaces, such as paved community roads for electric golf carts or flat golf courses, a 36V cart is more than enough to meet your daily needs and get you around smoothly and comfortably.
In terms of purchase cost, 36-volt electric golf buggies and their repair parts are relatively inexpensive, which may be an attractive factor for consumers on a budget. However, as the industry grows, 48v systems are becoming more mainstream. While their initial investment may be higher, the availability of parts will be more plentiful in the future due to increasing ownership in the market, and their energy-efficient nature may save you some money in the long run.
Standard Speeds
Whether it’s a standard 36V or 48V electric golf vehicle, their top speed is usually around 21 mph (ca. 34 km/h). This speed is designed to meet the demands of driving on the course while ensuring a safe ride.
Ways to increase speed
Replace with larger tires: Using larger diameter tires can increase the speed of your cart. This is because the larger the diameter of the wheel, the farther the cart will travel at the same frequency of rotation, and the speed will increase accordingly. Typically, a standard golf buggy can accommodate tires up to 20 inches (ca. 51 cm) in diameter without the installation of a lift kit or pads. Upgrading from the common 18-inch tires to 20-inch tires will increase the speed of the cart by approximately 2 mph (3.22 km/h).
Install a Torque/Controller Upgrade Kit: By using a Torque Upgrade Kit or Controller Upgrade Kit, you can increase the torque of your electric golf cart, which in turn increases your speed. However, it is important to note that the factory speed of your electric-powered golf cart is set for safety reasons. If you decide to upgrade the speed of your electric golf vehicle, it is important to prioritize safety and strictly follow the instructions for installation and tuning to avoid compromising driving safety.
In summary, 48V electric golf carts are better for hilly courses or heavier loads and have the power and torque to keep them running in all sorts of complex conditions. The 36v cart is better suited for light-duty use on flat terrain, with a smooth ride, but may struggle with steep hills or frequent starts and stops.
The 48V electric golf buggy, with its higher energy efficiency and longer range, is a better choice for those who need to be on the course for longer periods or those with larger courses. A single charge is all you need for a full day’s use, eliminating the need to search for charging facilities.
Although the initial purchase cost and maintenance parts for 36-volt electric golf carts are relatively low, as 48-volt systems become more mainstream in the industry, the availability of parts and maintenance will gradually increase, and in the long run, 48-volt carts may narrow the gap or even become more advantageous than 36v carts in terms of overall cost of use due to their energy efficiency.
If you play mostly on flat courses, are looking for affordability, and don’t use your cart very frequently, then a 36-volt electric golf cart will be sufficient to meet your needs. But if you play on a course with a lot of rolling terrain, need to carry additional power-hungry equipment such as coolers, or have a high demand for range and durability, a 48-volt electric golf cart is the way to go.
For most golfers, a 48-volt cart is a better investment in terms of performance, efficiency, and future-proofing. However, a 36-volt electric golf vehicle is not without value and can still be a cost-effective option for those who only use the flat course for recreational use and are on a budget. The key is to make the best decision for you based on your actual needs and usage scenarios.
In theory, it is possible to convert a 36-volt electric golf cart to 48-volt, which usually involves replacing the existing batteries with a set of six 8-volt batteries connected in series, rather than six 6-volt batteries as is common with 36v systems. However, this modification is not recommended because of the many potential risks involved. There are several potential risks associated with this modification, including the need to consider whether the components of the electric golf cart can withstand the higher voltage, or else damage to the components could result, affecting the normal use of the electric golf cart or even causing a safety issue. Therefore, if you have the idea of modification, it is highly recommended to consult a professional technician to ensure that the modification process is safe and correct to achieve the best performance.
To convert a 36V electric golf vehicle to 48V, it is necessary to replace six 6-volt lead-acid batteries with six 8-volt batteries. Pay attention to the space in the battery compartment, use the appropriate cables and connect them in series, and make sure the connection is stable to ensure stable power transmission.
Before starting the modification, check the parameters of the motor carefully; old or unsuitable ones need to be replaced. The controller must also be recalibrated or replaced with a new one, and at the same time, pay attention to the compatibility with the battery management system so that the various components work well together.
Due to the increase in voltage, the wiring needs to be replaced with higher voltage-resistant wires. A thorough inspection of the electrical equipment in the vehicle will be done, and if it cannot handle 48 volts, it will be adapted to the new voltage by adding a step-down module or replacing it directly with a new one.
If the modification process is carried out incorrectly, it is very easy to cause a short circuit, which may lead to a fire. Moreover, the original brakes may not have sufficient performance after the modification, which may pose a serious risk to driving safety.
After completing the modification, use professional equipment to test the voltage of the electrical system. No-load and load tests on the motor and accurate debugging of controller parameters so that the electric golf vehicle runs smoothly and efficiently.
Before modification, be sure to consult the local traffic control department to understand the relevant laws and regulations in detail. Illegal modification will face fines and vehicle bans, and some areas also require testing and a change of registration after modification.
Modification involves the purchase of new parts and labor hours; the cost is not low. Weighing the cost, performance improvement, and second-hand value, it may be more cost-effective to purchase a new vehicle than to retrofit.
Most golf vehicles come from the factory with a lead-acid battery. These batteries are relatively inexpensive and have proven technology to meet the power needs of the average electric golf cart.
A 36V battery is suitable for base-model electric golf carts that operate on flat terrain, providing consistent and reliable power for simple everyday travel. The 48v battery demonstrates higher performance, outperforming the 36V battery in hill-climbing ability, acceleration, and torque output. In addition, 48V battery systems typically run longer, providing longer-lasting power to the golf cart. When choosing a battery system, you’ll want to consider the specific model of your golf cart and the terrain you drive on most often to ensure you’re choosing a battery system that will provide enough power for your cart and meet your needs.
This detailed comparison of 48V and 36V electric golf carts in terms of power, performance, efficiency, cost, terrain suitability, and battery systems will give you a deeper understanding of these two different voltage golf carts. When making your purchasing decision, be sure to consider them thoroughly based on your actual needs and usage scenarios.
