The new Shimano DN300 battery features the same waterproof design that Di2 users have loved for generations. Now with 3 EW-SD300 ports, it delivers stable power to Shimano's 12-speed road front derailleurs and rear derailleurs (if a fully wired option is selected).

THE SCIENCE OF SPEED: Shimano Di2 BT-DN300 Battery

With the same size as its predecessor, the slim DN300 battery can be housed inside seat posts or frames ensuring a clean aesthetic. Now with 3 ports, the DN300 simplifies wiring to front and rear derailleurs, supplying stable power at all times. The third port is for riders who seek the redundancy of Shimano's 12-speed Di2 wired option.
