51V 105AH Skinny LiFePO4 Battery / Heated - Individual

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.
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.
