When it comes to powering your golf cart, understanding the battery requirements is crucial for optimal performance and longevity. One of the key metrics to consider is the amp-hour (Ah) rating of the batteries. This article will explore the factors that influence the number of Ah needed for a golf cart, providing you with data-driven insights to make an informed decision.
Understanding Amp-Hours (Ah)
Amp-hours (Ah) measure the battery's capacity, indicating how much current a battery can supply over a specific period. For instance, a 100Ah battery can deliver 100 amps for one hour or 10 amps for 10 hours. The higher the Ah rating, the longer the battery can power your golf cart before needing a recharge.
Factors Influencing Battery Requirements
-
Golf Cart Voltage System
Most golf carts operate on either a 36-volt or 48-volt system. The voltage system directly affects the number and configuration of batteries needed. For example:- A 36-volt system typically uses six 6-volt batteries.
- A 48-volt system usually requires six 8-volt batteries or eight 6-volt batteries.
-
Desired Range
The range of your golf cart, or how far you want to travel on a single charge, significantly impacts the Ah requirement. Here’s a general guideline:- For a 36-volt system, each 6-volt battery should ideally have around 200-225Ah.
- For a 48-volt system, each 6-volt battery should have approximately 150-180Ah, or each 8-volt battery should have about 170-190Ah.
-
Weight and Space Constraints
The physical space available in your golf cart and the weight capacity are also crucial factors. Higher Ah batteries are generally larger and heavier, so you need to ensure they fit within the designated battery compartment and do not overload the cart.
Example Calculations
Let’s break down the requirements using some example scenarios:
Scenario 1: 36-Volt Golf Cart
-
Battery Configuration: Six 6-volt batteries
-
Desired Ah per Battery: 225Ah
-
Total Ah Needed: 225Ah x 6 = 1350Ah
In this scenario, you would need six 225Ah 6-volt batteries to achieve optimal performance and range.
Scenario 2: 48-Volt Golf Cart
-
Battery Configuration: Six 8-volt batteries
-
Desired Ah per Battery: 190Ah
-
Total Ah Needed: 190Ah x 6 = 1140Ah
Alternatively,
-
Battery Configuration: Eight 6-volt batteries
-
Desired Ah per Battery: 150Ah
-
Total Ah Needed: 150Ah x 8 = 1200Ah
Depending on your preference and available space, you can choose between six 8-volt batteries with 190Ah each or eight 6-volt batteries with 150Ah each.
Real-World Data
According to industry standards and user feedback, the following data reflects common battery configurations and their performance:
-
36-Volt System (225Ah Batteries): Provides an average range of 25-30 miles per charge, depending on terrain and load.
-
48-Volt System (190Ah Batteries): Offers a range of 20-25 miles per charge, with better performance on hilly terrains due to higher voltage.
-
48-Volt System (150Ah Batteries): Typically gives a range of 20 miles per charge, suitable for flatter courses.
Conclusion
Determining the right Ah batteries for your golf cart involves understanding your cart’s voltage system, desired range, and physical constraints. By using the guidelines and data provided, you can select the appropriate batteries to ensure optimal performance and longevity for your golf cart.
Remember, while higher Ah batteries provide more extended range and better performance, they also require more space and add weight. Balancing these factors is key to choosing the perfect battery setup for your needs. Whether you are upgrading your existing batteries or purchasing new ones, making an informed decision will enhance your golfing experience and extend your cart’s lifespan.

Given the specifications and usage pattern you’ve described, a 36V Li-ion battery with a capacity of at least 100Ah would be suitable for your needs. This should provide enough power for your golf cart to handle the moderately hilly terrain and duration of use without frequent recharging, while also accommodating the occasional use of lights through the 12V converter.

I have a 1987 Ezgo. 36v. Slow but adequate. I do not know the controller amperage draw but I’ve read it may be as low as 35 amps (it is a slooooow cart)… Will be changing batteries within a year. Want to change from 6 Duracell 6v 240 AH batteries to a single 36v Li-ion battery, adding a 12v converter to power the lights (rarely used). No radio, no A/C, no phone charger, no fan… Cart weight after the battery change will be 1000-1200 pounds, fully loaded. Tires and cart are all are stock. Golf course is moderately hilly. Duration of use is less than 4 hours. How many amp hours would you recommend for the new Li-ion battery? Thanks
