Ultegra Di2 12v Derailleur Battery

With the same size as the previous model, the slim DN300 battery can be housed inside the seatpost or frame, for added aesthetics. Now with 3 ports, the DN300 battery simplifies the wiring of the front and rear derailleurs, and provides stable power at all times. The third port is for riders who want to keep the Shimano Di2 12-speed wired option.
