Shimano Di2 E-Tube Internal Battery SM-BTR2

The Shimano E-Tube Internal Battery SM-BTR2 fits certain seat posts like the Pro Vibe, Pro PLT, and Pro Vibe 7S designed for an internal battery. It is a bit lighter than the external battery, and it helps to give your bike a clean look. The battery is charged with a USB power adapter (SM-USB1) through port on EW90-A/B cockpit junction box or SC-705 display unit so there is no need to remove the battery for charging. It has about the same long battery life as the external battery.

Features

  • 58 grams
  • Requires a seatpost designed specifically for use with this battery
  • Same battery life as external battery
  • 1.5 hour charge time
  • Requires SM-BCR2 battery charger (sold separately)

All Di2 components on the bicycle require the same firmware version. Using Di2 components with different firmware versions may cause malfunctions.
