Upgrade Your E-Z-GO Terrain 250 to Fleet Lithium
A Terrain 250 is a jobsite vehicle, and jobsite vehicles get deep-cycled hard and charged inconsistently — the two fastest ways to ruin flooded batteries. The 51V Fleet Lithium pack tolerates partial charging, holds full output loaded, and cuts about 230 lb from the six 8V factory pack.
