Many newer ICON golf carts are equipped with lithium batteries, and some models, like the 2025 iCON i40L, come standard with them. ICON's proprietary ECO Lithium Battery offers a powerful and efficient energy solution for their carts, ensuring better performance and longevity compared to traditional lead-acid batteries.

ICON Golf Carts and Lithium Batteries

In recent years, lithium batteries have become a popular choice for many golf cart owners due to their numerous benefits, such as longer lifespan, faster charging times, and lighter weight compared to traditional lead-acid batteries. Many of ICON’s newer models now come with lithium batteries, and the company offers its proprietary ECO Lithium Battery, which is designed specifically for its carts. The 2025 iCON i40L, for example, features a 51V/105Ah ECO Lithium Battery, offering improved energy efficiency and performance.

ICON's Authorized Lithium Battery: The ECO Battery

ICON uses its own ECO Lithium Battery, which is the only authorized lithium battery for their vehicles. This battery is designed and engineered by ICON EV to ensure optimal performance, compatibility, and safety with their golf carts. One of the standout features of the ECO battery is its 8-year limited warranty, which includes 3 years of full replacement value and 5 years of prorated coverage. This long-term warranty reflects ICON's confidence in the durability and reliability of the battery.

Features of the ECO Lithium Battery

The ECO Lithium Battery is not only known for its long lifespan but also for its advanced safety features. It includes LIMP mode technology, which helps protect the battery and cart from potential issues by automatically limiting power if an abnormal condition is detected. Additionally, the battery offers real-time communication with the cart's electrical system, ensuring that any potential issues are detected early, which enhances the overall reliability of the cart. This makes it a great choice for those who prioritize safety and longevity in their golf cart.

Other Lithium Battery Options for ICON Golf Carts

While the ECO Lithium Battery is the only authorized option for ICON carts, other third-party lithium batteries are also compatible with these vehicles, though they are not officially endorsed by ICON EV. Some of these third-party options include:

• Vatrer Power: Vatrer Power lithium batteries are designed to be compatible with ICON golf carts. These batteries offer advanced features such as mobile app monitoring, allowing users to track battery performance and health directly from their smartphones. However, it’s important to note that these batteries are not officially approved by ICON, and their installation may void warranties or require specific installation procedures.
• Allied Batteries: Allied provides conversion kits that allow users to replace their lead-acid batteries with lithium batteries. These kits are designed to integrate seamlessly into ICON carts, offering an upgraded power solution. Again, these conversions are not officially authorized by ICON, so users should be aware of any potential compatibility issues or warranty concerns.
• Lithium Rhino: Lithium Rhino batteries have also been successfully installed in ICON carts by some users. These batteries provide the benefits of lithium technology, such as longer lifespan and faster charging, but their integration into ICON carts requires some technical expertise and may not be supported by the manufacturer.

How Do I Know If My Golf Cart Batteries Are Lithium?

Determining whether your golf cart uses lithium batteries is relatively easy if you know where to look. Here are a few ways to check:

• Check the Battery Label: Lithium batteries are often clearly labeled as such. Look for markings such as “LiFePO4” or “Lithium-ion” on the battery casing.
• Battery Voltage: Lithium batteries typically have higher voltages (usually between 48V and 72V) compared to traditional lead-acid batteries, which are commonly 36V or 48V.
• Battery Weight: Lithium batteries are much lighter than lead-acid batteries. If your battery feels significantly lighter, it’s likely lithium.
• Owner’s Manual: Check your golf cart's owner’s manual for details on the type of battery it uses. This will provide accurate information about the battery specifications and maintenance requirements.

What Are the Disadvantages of Lithium Batteries in Golf Carts?

While lithium batteries offer many benefits, there are some potential disadvantages to consider, including:

• Higher Initial Cost: One of the most significant drawbacks of lithium batteries is their higher upfront cost compared to traditional lead-acid batteries. However, this cost is often offset over time due to the longer lifespan and reduced maintenance needs of lithium batteries.
• Temperature Sensitivity: Lithium batteries can be sensitive to extreme temperatures, particularly cold weather. In very cold conditions, lithium batteries may experience reduced performance or charging issues. However, many lithium batteries come with built-in temperature protections to mitigate these effects.
• Compatibility Issues: Installing a third-party lithium battery that is not authorized by the manufacturer may cause compatibility issues. While many third-party batteries are designed to work with ICON carts, using them may void warranties or lead to performance issues if not properly integrated.

Conclusion

ICON Golf Carts are equipped with advanced lithium battery options, including their proprietary ECO Lithium Battery, which is designed specifically for their vehicles. These batteries offer a range of benefits, including longer lifespan, faster charging, and improved performance. While other third-party lithium batteries like those from Vatrer Power, Allied, and Lithium Rhino are available, ICON recommends using their own ECO Lithium Battery to ensure optimal performance and safety.
