With the new Shimano internal SM-BTR2 Di2 Battery, charging is a straightforward affair once you have the compatible parts. You will need one of the new E-Tube Cockpit Junction Boxes (the SM-EW90-A, with three ports, or SM-EW90-F, with five ports) as well as this new E-Tube SM-BCR2 battery charger. Both of these junction boxes were built with an external charging port for the new charger. This is the only way to charge the new battery.

Like a camera battery charger, one end of the SM-BCR2 charger connects to either your computer or wall socket via a USB cord. The other attached cord plugs directly into your E-Tube Cockpit Junction Box. Similar to the external battery, the new SM-BTR2 Di2 internal battery takes 1.5 hours for the battery to receive a complete charge.

The Shimano E-Tube Battery Charger is included with the necessary charging cord.
