Controller Compatibility
The GEM e4 uses a factory 72V controller. The 76.8V Fleet Lithium pack is designed to work with the factory system. No controller reprogramming is typically required for standard installations.
Will this fit my GEM e4?
Yes. The BR3374 bracket kit ensures a factory-fit installation. No modifications required.
Do I need to reprogram my controller?
No. The factory 72V controller is compatible with the 76.8V lithium pack out of the box.
How long does installation take?
30–60 minutes with basic hand tools.
Does it work in cold weather?
Yes. Built-in heater activates automatically below 32°F — standard on every pack.
*Range estimates are maximums under ideal conditions (flat terrain, single rider, 12–15 mph, 70°F). Actual range varies with terrain, weight, speed, and temperature.
