Wire up your drivetrain and never think about power again with the Di2 Power Kit
What Our Gearhead® Experts Are Saying:
"I built the Di2 Power Kit into my road bike ahead of a multi day gran fondo, and having the battery, charger, and junction boxes all matched from the same system meant setup took an afternoon instead of a weekend. The wireless unit let me check battery status and gearing straight from my head unit, so I never had to guess how much charge I had left mid ride. It's the kind of system that disappears into the background until the exact moment you need it to work."
The Di2 Power Kit from Backcountry is built for the ride where shifting is the last thing you want to think about, a century on rolling terrain, a gran fondo with more climbing than the elevation profile let on, the kind of day where consistency matters more than anything else. We wired the battery into the seatpost, tucked the wireless unit into the mix, and rode off without a single thought about power for the rest of the day.
The BT-DN110-A battery hides completely inside the frame, preserving clean lines while feeding reliable power to every shift. The E-Tube junction boxes route that power efficiently between components, while the internal charger tops everything off in about the time it takes to change and grab a coffee. Add in the inline wireless unit, and gear position and battery life show up right on the head unit, no guesswork required for the next long day in the saddle.
