What Battery Is In A E-Z-GO Golf Cart? - Copow

EZGO golf cart batteries typically use either a 36V or 48V system, depending on the model year and configuration.

The most common battery types include flooded lead-acid batteries, maintenance-free AGM sealed batteries, and the newer lithium battery packs, most of which are built with the safer and more durable LiFePO₄ (lithium iron phosphate) chemistry.

Each battery type offers different levels of driving range, maintenance requirements, and lifespan, all of which directly affect the cart's overall performance and user experience.

What Are the Most Important Qualities of a Golf Cart Battery?

The core qualities of a golf cart battery focus on driving range, safety protection, durability, and compatibility, and the performance of an EZGO golf cart battery in these areas directly determines whether the vehicle can sustain long periods of operation, while also affecting overall costs and safety. A stable driving range ensures you can complete a full 18-hole round without worry, reliable safety features help reduce the risk of battery failures, and excellent durability along with good compatibility minimizes the need for frequent replacements or complex modifications.

Why Does an E-Z-GO Golf Cart Battery Need Stable and Sufficient Driving Range?

This is key to ensuring the proper operation of an EZGO golf cart battery. Golf carts typically need to run continuously on the course, and the battery capacity (Ah) directly determines the driving range. For example, a 48V 105Ah LiFePO₄ battery can provide approximately 64–80 km of range, which is sufficient for the daily needs of most courses. Stable discharge performance is also extremely important. Only when the golf cart battery maintains a proper discharge rate can the cart sustain continuous power during acceleration or uphill driving, preventing sudden drops in performance while in use.

Golf Cart Batteries Need Comprehensive and Reliable Safety Features

EZGO golf carts are typically used on outdoor courses, so battery safety is especially important. On one hand, the battery must have good environmental adaptability and be able to charge and discharge normally within a wide temperature range of -20℃ to 60℃ to cope with different climates.

On the other hand, it should have complete protective mechanisms. LiFePO₄ golf cart batteries usually include a BMS (Battery Management System) that provides multiple protections against overcharging, overcurrent, and short circuits. Copow's LiFePO₄ batteries also feature an IP67 protection rating, effectively preventing dust and water intrusion and reducing the risk of leakage or thermal runaway.

The Durability of Golf Cart Batteries Directly Affects Ownership Costs

The durability of a golf cart battery is mainly reflected in its cycle life. High-quality batteries can withstand frequent charging and discharging. For example, LiFePO₄ batteries can achieve a cycle life of over 6000 cycles and a service life of more than 10 years. Even high-quality lead-acid batteries typically last only 4 to 5 years, with a maximum of around 500 deep cycles. In addition, some EZGO golf cart batteries use special designs such as tubular plate structures. These designs improve the battery's ability to handle high-current charging and discharging and reduce wear caused by improper operation during daily use, further extending durability.

Standard Golf Cart Batteries Should Offer Compatibility and Low Maintenance

High-quality golf cart batteries typically provide good compatibility. They can work with mainstream and even older EZGO electric golf carts, allowing you to replace old batteries without major modifications to the wiring. Some brands, such as Copow, also offer OEM customization, making it possible to fit carts with different passenger capacities and models. At the same time, low maintenance is an important consideration. For example, AGM batteries and lithium batteries do not require frequent checking of electrolyte levels or adding distilled water. You only need to follow proper charging procedures, which significantly reduces the daily maintenance workload.

Why EZGO Electric Golf Carts Need Deep Cycle Batteries?

The usage characteristics of EZGO golf carts are highly compatible with the advantages of deep cycle batteries. These carts often require long periods of low-speed operation and frequent charging and discharging, while frequently facing load changes such as climbing hills or carrying passengers and equipment. In such situations, deep cycle golf cart batteries can provide stable power output, withstand deep discharges and frequent cycles, and effectively prevent the rapid wear or power interruptions common with standard batteries.

Deep cycle batteries can meet continuous driving demands

Most EZGO golf carts are designed for 18 holes or more, requiring the battery to operate for long periods. Regular car batteries cannot meet this demand. However, deep cycle batteries can safely discharge up to 80 percent of their total capacity without damaging the battery's lifespan, which is known as deep discharge. For example, a fully charged 48V 105Ah lithium iron phosphate battery can power a golf cart for 54 holes in a single use.

Deep cycle golf cart batteries withstand frequent charging and discharging

On golf courses, EZGO golf carts may run multiple rounds per day. After each round, the battery is recharged and then used for the next round. This repeated charging and discharging is called high-frequency cycling. Lead-acid golf cart batteries can wear out quickly under such conditions, typically lasting only 1 to 2 years. Deep cycle batteries, however, are built more robustly with thicker plates and dense active materials, allowing them to handle 2000 to 6000 cycles or more, with a lifespan of 5 to 8 years.

Deep cycle batteries provide stable power under varying loads

EZGO golf carts require more power when climbing hills or carrying heavy loads. Deep cycle batteries can deliver consistent power, maintaining voltage even on steep slopes, which prevents the cart from losing power or stopping mid-route.

Deep cycle batteries are compatible with specific cart models without extra modifications

EZGO golf carts usually use 36V or 48V systems composed of multiple 6V or 8V deep cycle batteries connected in series. These batteries can be used directly without modifications. AGM and lithium iron phosphate batteries are low maintenance and long-lasting, and some models can reach 80 percent charge in just 1 to 2 hours, saving on maintenance and operational costs.

Deep cycle golf cart batteries perform reliably in various outdoor conditions

These batteries can retain 70 to 80 percent of their capacity even at temperatures as low as -20°C. They also feature IP67 dust and water resistance, with sealed terminals and aluminum alloy housings to protect against dust, water, and minor impacts, ensuring stable performance in outdoor environments.

How to Choose the Right Battery for Your EZ-GO Golf Cart?

When selecting a battery, first make sure the voltage and size are compatible with your EZ-GO golf cart. Then, consider your usage frequency and the terrain of the golf course when choosing between lead-acid batteries and lithium iron phosphate batteries. You should also take into account battery quality and after-sales support. If you plan to upgrade, ensure the new battery is compatible with your cart. This approach helps balance performance, cost, and ease of use.

Ensure the Battery Is Compatible with Your EZGO Golf Cart

EZ-GO golf carts use different voltage battery systems, commonly 36V and 48V. The battery configuration varies by model:

• EZGO TXT uses six 6V lead-acid batteries connected in series to form a 36V system.
• EZGO RXV uses four 12V batteries connected to form a 48V system.

When selecting a battery, you must strictly follow the original voltage specifications to avoid damaging the cart's controller.

Select the Battery Type Based on Your Needs

Lead-Acid Batteries

• Suitable for: Users with a limited budget or carts that are used infrequently.
