Upgrade Your E-Z-GO Express L6 to Fleet LithiumEight 6V batteries is roughly 420 lb of lead in the belly of an Express L6 — and that weight is why the cart feels sluggish loaded and why the pack fades late in the day. Replacing it with one 51V Fleet Lithium pack cuts about 300 lb, restores hill speed, and gives you the same power output from the first run to the last.Choose Your Capacity Capacity Range* Best For 51V 65Ah Up to 27 mi Stock carts only 51V 105Ah Up to 50 mi Daily driving 51V 168Ah Up to 75 mi All-day use 51V 210Ah Up to 90 mi Max range, fleet use 65Ah is for stock motors and controllers only.
