Shimano BT-DN300 Internal Battery

Shimano BT-DN300 Internal Battery

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

The same size as its predecessor, the slim DN300 battery pack can be tucked inside seatposts or frames, ensuring a clean aesthetic. Now with 3 ports, the DN300 simplifies wiring to the derailleur and derailleur, delivering stable power at all times. The third port is for riders looking for the redundancy of Shimano's cabled Di2 12-speed option.

• Compatible with the slimmer next-generation SD300 power cable and systems beyond the R9250/R8150 series
