The updated Shimano Di2 BT-DN1110 battery is now Bluetooth-enable and fully compatible with Shimano's E-Fly module. This allows the battery to talk to a Bluetooth-compatible cycling computer to deliver battery and system information, so you'll know when it's time to recharge. This slim battery fits easily inside most seatposts (aero posts may require an adapter), connects up with Shimano's standard E-Tube technology, and is good for roughly 1,200 miles per charge (depending on conditions and number of shifts).
