Upgrade Your E-Z-GO Workhorse 1000 to Fleet Lithium
The Workhorse 1000 carries more than the 800 on the same 36V six 6V lead pack, so it is the one that runs out of power first. A 38V Fleet Lithium pack delivers 300A continuous with an 800A surge, holds that output loaded, and takes roughly 260 lb of lead out of a vehicle whose whole job is carrying weight.
