Why Do Golf Carts Have So Many Batteries

Why Do Golf Carts Have So Many Batteries?

Electric-powered golf carts require multiple batteries to provide the necessary power to start the engine and propel the vehicle. 

The voltage of the batteries is a crucial factor in determining the overall power of the golf cart, and typically, golf carts come with 36, 48, or 72-volt batteries.

The number of batteries required for a golf cart depends on the voltage of each battery and the total voltage needed for the golf cart. 

For example, a 36-volt golf cart can use one 36-volt battery or six 6-volt batteries, provided that the full voltage adds up to the cart’s voltage requirement.

It is essential to avoid upgrading or downgrading the current battery system when replacing one or more of the golf cart’s batteries. 

This is because the golf cart’s battery charger is designed to charge the same type of battery, and mismatched batteries could potentially damage the golf cart.

The battery pack of a golf cart is typically located underneath the seat, and the voltage of the deep-cycle battery can be identified by the number of cells on the battery. 

Each cell represents 2 volts of power, with 6V batteries having three cell caps, 8V batteries having four, and 12V batteries using six.

Golf Cart Battery Voltage Vs Amperage

Voltage is the force that drives electric charge through a circuit, while amperage is the measure of the flow of electric charge through a circuit.

Both are essential concepts in understanding and working with electrical circuits. Here’s a quick comparison table between voltage and amperage:

ExampleBattery voltageCurrent through a wire

The performance of a golf cart’s battery is primarily determined by its voltage and amperage levels. 

Voltage is responsible for providing power to the golf cart, with higher voltage enabling the engine to use the battery’s power more efficiently. This increases speed and acceleration, making it a crucial factor to consider.

In addition to power, the voltage can also impact the charging speed of the battery. On the other hand, amperage is responsible for determining the efficiency of the golf cart. 

A higher amperage means that the golf cart can cover more distance on a single charge, providing a longer and more relaxed ride.

Regarding deep-cycle golf cart batteries, 6-volt batteries usually have higher amperages than 12-volt batteries. 

Therefore, if you are looking for an extended and comfortable ride, it’s recommended to choose a 6-volt battery pack.

However, if you desire a sporty and more responsive performance, selecting a golf cart with 2-volt batteries is a better option. 

Therefore, determining your priorities and user needs is crucial when selecting the appropriate golf cart battery voltage and amperage.

Types of Golf Cart Batteries

Usually, deep-cycle lead-acid batteries are used in golf carts. These batteries are created expressly to dissipate a significant quantity of energy over an extended length of time before being recharged. There are a few lead-acid battery types that are often utilized in golf carts.

Flooded Lead-Acid Batteries

The most typical battery used in golf carts is this one. They are reasonably priced, and with the proper upkeep, they may survive for a very long period.

Absorbed Glass Mat (AGM) Batteries

A fiberglass mat contains the electrolyte in these sealed lead-acid batteries. Compared to flooded lead-acid batteries, they can perform better and last longer while requiring no maintenance.

Gel Batteries

Another form of sealed lead-acid battery is the gel battery, which employs a gel-like material to store the electrolyte.

They can also offer exceptional performance and a longer lifespan while requiring little maintenance.

Lithium-Ion Batteries

They have a higher energy density, are lighter, and have a longer lifespan, which is why golf carts use them more frequently.

Although they are more expensive than lead-acid batteries, in the long term, they can offer superior performance and lower maintenance expenses.

Note: Ultimately, the choice of battery will rely on the unique requirements and preferences of the golf cart owner, taking into account elements like budget, performance requirements, and maintenance concerns.
