Shimano Ultegra/Dura-Ace 9070 Di2 Battery Mount

The battery forms the Di2's heart. Its lithium ion technology guarantees a range of at least 2,000km [1,250 miles] after which it can be fully recharged in just ninety minutes.

The battery's status can be read from an indicator next to the handlebars so that you'll never be confronted with any unpleasant surprises. Derailleurs can also be reset or trimmed from this control unit.
