Eco Battery 36V 105Ah Lithium Bundle — Club Car DS, EZGO TXT & Yamaha G-Series

Upgrading your 36V golf cart to lithium starts here. The Eco Battery 36V 105Ah Lithium Bundle is a fitment-based conversion kit built specifically for Club Car DS 36V, EZGO TXT 36V, and Yamaha G1–G16 36V carts. It gives older 36V electric golf carts a clean lithium upgrade path without piecing the system together one part at a time — the right support components for your specific cart are included based on the fitment you select above.

This is a fitment-based bundle built around Eco Battery’s 36V 105Ah cube battery, with included parts changing based on the cart selected above. That matters because these 36V platforms do not all use the same charge-port setup, state-of-charge components, mounting hardware, or support accessories.

For the right electric cart, this is a strong replacement for worn lead-acid batteries and a practical option for carts already running upgraded motors and controllers. The goal is to give you stronger usable power, less maintenance, and a more dependable day-to-day setup than the battery pack you are replacing.

If you are still comparing lithium options, our Lithium Knowledge Center is a good place to start.

It is also backed by a Limited Lifetime Warranty with 6 years of full replacement, which is one of the biggest reasons many golf cart owners choose Eco Battery when stepping up to lithium.

Customers can expect roughly 15–35 miles per charge, depending on cart setup, terrain, tire size, driving style, payload, and overall efficiency.

At the center of the package is Eco Battery’s 38.4V nominal 105Ah lithium battery with 4,032Wh of energy, Bluetooth, CAN communication, IP67 protection, and strong discharge capability for real golf cart use. It delivers 250A max continuous discharge, 600A max discharge for 5 seconds, and 550A max discharge for 10 seconds.

Top Features of the Eco Battery 36V 105Ah Bundle

Built Around Eco Battery’s 36V Cube Platform

This bundle centers around Eco Battery’s 36V 105Ah cube battery, giving older 36V golf carts a high-capacity lithium setup built for real cart use instead of a stripped-down battery-only replacement.

Matched to the Cart You Select

This is not a universal kit. Included parts change by application, which helps reduce guesswork on charge-port parts, state-of-charge meter setup, mounting hardware, and wake-up components.

A Better Fit for Older 36V Electric Carts

This bundle is a strong fit for common 36V applications like Club Car DS, EZGO TXT, and Yamaha G1-G16, where owners are often moving out of an aging lead-acid system and want a cleaner lithium conversion path.

Strong Output for Stock and Upgraded Setups

This battery works well in standard 36V carts, but it also has the discharge output to support many carts running upgraded motors and controllers.

Smart Features You’ll Actually Use

Bluetooth, CAN, mobile app access, and over-the-air software updates make it easier to monitor battery status and keep the system more usable long term.

Protection Features That Matter in Real Cart Use

The battery uses LiFePO4 chemistry, prismatic cells, IP67 protection, charging freeze protection under 32F, and a powder-coated steel shell.

Optional 12V Converter

Some fitments show the DC-DC converter as optional if you do not already have one. If your cart or accessory setup still needs one, select YES above before ordering.

Should You Stay on 36V or Upgrade to 48V?

This is the most common question from 36V cart owners considering lithium. Here's the straightforward answer.

If your cart is stock and running well on 36V, staying at 36V is the right call. A 36V lithium conversion delivers noticeably better performance, longer range, and zero maintenance compared to your existing lead-acid pack — without the cost and complexity of a full voltage conversion.

If you're already running an upgraded motor and controller and want significantly more speed and torque, a 48V upgrade is worth exploring. But that's a separate project involving controller replacement and rewiring — it's not a battery swap.

For most Club Car DS, EZGO TXT, and Yamaha G-series owners, the 36V lithium bundle is the cleaner, more cost-effective path. If you want to compare options, browse our full Eco Battery collection.

Heated Battery Option

If you ride or charge your cart in colder weather, the heated battery option is worth considering.

The main purpose of the heated battery is to help allow charging in below-32°F weather. Standard lithium batteries should not be charged when battery temperature drops below freezing. Choosing the heated version gives you a better option for charging in colder conditions and makes the package a stronger fit for winter use.

This is especially helpful if your cart is stored or charged in:

• Unheated garages
• Sheds
• Barns
• Colder seasonal climates

If your cart stays in a climate-controlled space year-round, you may not need the heated option. But if there is a good chance your battery will be charged in freezing or near-freezing temperatures, it is a smart upgrade to consider.

Fitment

This package fits 36V electric golf carts shown in the dropdown selection. Common applications include:

• Club Car DS 36V

Does not fit

• Carts with a factory lithium battery

Before You Order

Before ordering, verify:

• Your cart appears in the dropdown fitment
• Your cart is electric
• Your cart is 36V
• Your cart is not factory lithium
• That the selected package includes the support parts you expect for your cart

A few setup notes also matter:

• Many fitments show the DC-DC converter as optional if you do not already have one, you need this.
• If the selected package includes a CAN-enabled charger, CAN must be connected for charging to work correctly
• The battery must be powered on with the illuminated power button to accept a charge
