51V 105Ah Skinny LiFePO4 Heated Lithium Golf Cart Battery

Upgrade your golf cart with the 51V 105Ah Skinny LiFePO4 Heated Battery, engineered for maximum power, extended range, and reliable performance in all conditions. Built with advanced Lithium Iron Phosphate (LiFePO4) technology, this high-capacity battery delivers stronger acceleration, longer run times, and virtually maintenance-free operation compared to traditional lead-acid batteries.

The slim “skinny” design makes it ideal for carts with narrow battery trays, providing a powerful lithium upgrade without complicated modifications.


Battery Only vs. Complete Kit

Here's the thing about this heated battery: it ships without its charger — and charging is exactly what the heated feature is for. The Eco Battery 48V 105Ah Skinny Bundle brings the charger and the cart-matched install parts along, starting at about $30 more, and selecting the Heated dropdown option keeps the below-32°F charging working with it.

Why Upgrade to a 51V 105Ah Lithium Battery?

Lithium golf cart batteries provide consistent voltage output and significantly longer lifespan compared to lead-acid systems. With a 105Ah capacity and approximately 5.3 kWh of energy, this battery supports longer rides, higher power demands, and improved efficiency.

Unlike traditional batteries that lose performance as they discharge, lithium batteries maintain steady power from full charge to near empty, delivering smoother performance and better torque.

Echo lithium battery upgrade

"The new ECO Battery is just flawless. The problem is with the 2016 easy go RXV, the instructions/youtube videos for the metal replacement tray is just nonexistent. Other than that, I love the install."

Robert S. (4/5)

Great Quality

"After many months of research, I have decided I was going to spend a little extra money on buying Eco. I was not disappointed in any regard. The install, quality, ease of accessories gave me confidence that I bought exactly what I wanted. I could not be happier with the way it has turned out. I have this installed on my 2015 EZGO TXT48 And it brought her back to life once again. The torque feels great and it moves like new once again."

Skinny Eco battery

"We changed from lead acid batteries to the skinny Eco battery in my 2007 Yamaha Cart. After slight changes in the frame it fits perfectly. We like the all metal box it is in and are very happy with our purchase."

Acid to Lithium - Mounted on HDPE Boards

"Just finished converting my EZGO TXT 2013 cart from acid batteries to lithium. I followed the advice from a review I read and put down two 1'x2' Hdpe Plastic High Density Polyethylene Board (basically 1/2 inch plastic cutting boards - from Amazon) where the 6 old batteries were. Then mounted the new EB 48v 105Ah Eco Skinny Battery to the front board and the charger to the other board. Worked out great! I absolutely love the battery and advise from Extreme Kartz!"
