Will this fit my Tomberlin E-Merge?
Yes. The BR5139 bracket kit provides a factory-fit installation for all E-Merge models. No modifications required.
Does my controller need reprogramming?
No. The factory Curtis 48V AC controller on E-Merge models accepts the 51V lithium pack without changes.
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.
