Upgrade Your E-Z-GO Shuttle 2+2 to Fleet LithiumA Shuttle 2+2 spends its day full of people and stopping constantly — the worst possible duty cycle for flooded batteries. Replacing the lead pack with one 51V Fleet Lithium pack keeps the cart at full speed on the last run of the day, takes hundreds of pounds off the chassis, and removes watering from the maintenance list entirely.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.
