The Fleet Lithium 51V pack is fully compatible — no reprogramming, no controller upgrade, and no wiring changes required. The slightly higher resting voltage of the lithium pack is within the operating range of the stock controller. Will this fit my EZGO TXT / RXV? Yes. The BR4402 bracket kit provides a factory-fit installation for both TXT and RXV models. No drilling or modifications required. Does my controller need reprogramming? No. The factory Curtis/GE 48V controller accepts the 51V lithium pack without any changes. This is a true drop-in replacement. 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.
