Shimano Di2 BT-DN110 Internal Battery

The BT-DN110 integrates flawlessly within your seatpost, allowing for a clean integration.

To charge the BT-DN110, simply connect a charger to one of the cockpit junction boxes. You can choose between the 3-port SM-EW90-A or the 5-port SM-EW90-F, both of which work seamlessly. With a full charge, this battery will power you through over 1,000 miles, even in the harshest cold weather conditions. Charging once a week is often more than sufficient to keep your battery topped up for any ride.

Shimano's junction box conveniently displays the battery power at any time with a simple press of a button. The light indicator shows green when fully charged, flashing green at 50%, solid red at 25%, and a flashing red light indicates critically low power.

Please note that the BT-DN110 is not compatible with Dura-Ace 7970 Di2 systems. For charging, you can use a USB power adapter (SM-USB1) through the port on the EW90-A/B cockpit junction box or SC-705 display unit.

Upgrade your previous Di2 systems to support the exciting new "Synchro Shift" feature with the BT-DN110. If you have the 6870 or 9050 Di2 systems with an internal battery, this hardware upgrade is a must. For external battery systems, upgrading the battery harness alone will suffice.

Embrace the future of cycling and enjoy the seamless integration of this remarkable battery into your bike.
