03 · Battery

Upgrade to Lithium

We convert carts from lead-acid to lithium, including carts that were never bought from us.

Black Phantom golf cart with brown seats

If your pack is at the end of its life, converting to lithium usually beats buying another lead-acid set. The cart gets lighter and stops needing water. It holds its speed until the pack is nearly empty instead of slowing down as the charge drops.

Conversion pricing FROM$2,199

Final price depends on your cart, voltage and the pack you choose. We quote after looking at the cart.

Bars compare the two pack types on each point. They are relative, not measured specs.
