Shimano SD300 Di2 Internal Battery

Shimano SD300 Di2 Internal Battery

The SD300 Di2 Internal Battery from Shimano is a powerful and lightweight Li-Ion internal battery for use with Shimano Di2 electronic 12-Speed E-Tube drivetrain systems.

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

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, always supplying stable power. The third port is for riders who seek the redundancy of Shimano’s 12-speed Di2 wired option.

Shimano E-Tube Compatible

E-Tube is Shimano’s “service” that uses websites or apps to maximize the enjoyment of riding a bicycle by connecting the riders, the bicycles and Shimano. Shimano’s genuine application E-Tube Project for Mobile allows you to customize your bike, update firmware, and maintain it by connecting it wirelessly to your bike. You can also get more detailed bike maintenance by connecting to your bike by wire with E-Tube Project via the Windows V4 application.
