Choosing the Right Size for Lithium Golf Cart Battery Conversion

Choosing the Right Size

When converting from lead-acid to lithium-ion batteries for your golf cart, selecting the correct battery size is crucial. The most common lead-acid golf cart batteries are GC2/GC8 size. Therefore, choosing a lithium battery of the same size, like the 48v lithium golf cart battery, makes the installation process much easier. This battery can fit directly into your existing battery compartment without the need for tray modifications.

Voltage Requirements

For carts using lead-acid 8v golf cart batteries, you typically need six batteries to achieve the 48 volts required to run the vehicle. Various batteries offer different energy capacities, but once you select a specific capacity, you must use it for the entire set unless you replace the whole group. For example, if you choose a 170 amp-hour battery, you must stick with that capacity for the battery’s lifespan.

Flexibility with Lithium Batteries

With 48V lithium golf cart batteries, you don’t need a fixed number of batteries to meet voltage requirements. Instead, you can install as many batteries as needed to meet your desired range and energy needs. In a typical golf cart, you can use anywhere from two to six batteries, depending on your required mileage.

Importance of Battery Spacers

If you opt for a lithium battery of the same GC2 size, using battery spacers might be necessary. These spacers fill empty slots in the battery compartment, ensuring the battery stays securely in place using the existing fixtures. This simplifies installation and ensures your battery is properly secured. It’s recommended to purchase enough spacers to fill all empty slots in your golf cart.

Custom Solutions

Lithium battery manufacturers like MANLY Battery offer custom solutions to match the dimensions of your original batteries, making the replacement process seamless. By providing the size of your old batteries to their consultants, you can get a lithium battery that fits perfectly, saving time and additional costs for modifications.

Determining Capacity Needs

When selecting a replacement lithium ion golf cart battery, consider the daily usage and current consumption of your golf cart. Multiplying these figures gives a good estimate of the necessary battery capacity. Lithium batteries are more efficient and have a higher capacity than lead-acid batteries. For instance, a 48v lithium golf cart battery with a capacity of 50 amp-hours can be paralleled to increase total capacity. Using two such batteries provides 100 amp-hours, while three batteries offer 150 amp-hours, and so on.


Selecting the right size for your lithium ion golf cart battery conversion involves understanding the compatibility with your existing battery setup, determining the necessary voltage and capacity, and considering custom solutions to simplify installation. By following these guidelines, you can ensure a smooth transition from lead-acid to lithium batteries, enhancing the performance and longevity of your golf cart.

How to Convert a Golf Cart to Lithium Batteries

Step 1: Determine the Correct Voltage and CapacityBefore you start your lithium ion golf cart battery conversion, you need to know your golf cart’s voltage and capacity requirements. Check your current golf cart batteries to see if you have six 8 volt golf cart batteries or six 6 volt golf cart batteries. Six 8 volt golf cart batteries mean your golf cart operates at 48V, while six 6 volt golf cart batteries mean it operates at 36V. This information is crucial when buying new lithium golf cart batteries.

For capacity (how far you can travel on a charge), consider your usage needs. A basic setup with two batteries might suffice for standard usage, but if you need more range, you can add more batteries (up to six). Unlike lead-acid batteries that connect in series, lithium batteries connect in parallel, allowing you to increase capacity without altering voltage.

Step 2: Remove the Lead-Acid BatteriesTo remove the old lead-acid golf cart batteries, start by disconnecting all support and retaining brackets. Use a wrench to disconnect the battery cables. Note the positive and negative cables connected to the speed controller. Once disconnected, you can remove the old batteries. These are quite heavy, so using a battery puller can help.

Clean the battery tray thoroughly and inspect the cables for any signs of corrosion. Clean or replace them if necessary.

Step 3: Place and Secure the Lithium BatteriesPlace the new lithium golf cart batteries in the battery tray. Since lithium batteries like those from Big Battery’s Eagle series have the same footprint as lead-acid batteries, they fit without modification. Ensure the weight is evenly distributed and the cable connections are accessible. Secure the batteries using the provided L-brackets and screws.

Step 4: Install Parallel Bus BarsParallel bus bars connect the batteries together and to the main controller. You can also connect tail leads here for the charger, battery meter, and a buck converter that steps down voltage from 48V to 12V for lights and accessories.

Mount the bus bars where the controller cables can reach. Keep all positive terminals on one side and negatives on the other. Tighten the nuts with a wrench to ensure secure connections.

Step 5: Cable Management and InspectionOrganize the battery compartment, tidy up the wiring, and secure everything with zip ties. Check each battery’s breaker (on the plug side) to ensure they are flipped to the “on” position.

If you choose to mount the charger on the cart, install it in the tray and connect it to the tail leads. You might want to install a waterproof outlet to replace the old charging port. When charging, you can use any extension cord to plug into the new port.

Once everything is set, replace the seat and start your journey.

Step 6: Charging the Lithium BatteriesYou need a charger compatible with lithium batteries for golf cart. Many lead-acid chargers are not suitable because they don’t output the correct voltage. The charger’s voltage should match or be less than the battery voltage. Lithium batteries need an output of 14.2 to 14.6 volts.

Also, consider the charger’s current rating. Too low, and charging will be slow; too high, and it may shorten the battery’s lifespan.
