Shimano Dura-Ace-Ultegra Di2 BTR1 Battery

The power house of Shimano Di2 is a long-life 7.4V Li-Ion battery that is both compact and reliable, taking shifting effort away from you. Excellent sealing and reliability have been proven through repeated field tests in various riding conditions, including extreme temperatures, rain, mud, and cobble stone roads

Features:

  • Using a hard wired battery system which is both light weight and accurate compared to current wireless technology (as a wireless system would require 4 batteries: one for the RD, one for the FD, and one for each shift lever)
  • The use of a single small and discreet battery is light weight, efficient and creates a robust and reliable system
  • One charge can give between 1000 and 2000 kilometre range depending on conditions and front mech operation (as this is the main power drain)
  • 500 times rechargeable life
  • Optional battery mount adapter is available if standard mount is not compatible
  • Reliable and secure water resistant terminals
  • Easily removable for charging
  • Weight: 68 grams

Rated 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by Fantastic My Di2 is on a Trek 6.5 and has worked flawlessly since Sept. First use was on a Century. After more than 600 miles I put the battery on charge ( even though the on board indicator said 1/2 ). The "no-trim feature" is the best part, though the speed and ease of shifting is also a nice feature. One you get past the price the Di2 is a joy to ride with. Feb 2, 2010 02 February 2010
