The Advent line (2, 4L, 6L) is Advanced EV's original platform — the most widely sold model with the largest aftermarket support. While all three share the same 48V system and bracket kit, the Advent is available in more seating configurations including specialty vehicles like beverage carts and ambulances. Do I need to reprogram my controller? No. Works with your factory 48V AC controller out of the box. How long does installation take? 30–60 minutes with basic hand tools. Remove the old lead-acid batteries, drop in the Fleet Lithium pack, connect cables, and ride. Does it work in cold weather? Yes. The integrated heater activates automatically below 32°F when plugged in for charging — it's standard on every pack, not an add-on. *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.
