Shimano Di2 battery BT-DN300

Now with 3 connectors, it provides stable power for SHIMANO's 12-speed road bike front and rear derailleurs (when selecting a fully cabled version). With the same dimensions as the previous model, the flat DN300 battery can be integrated into the seatpost or frame for a clean look. Now with 3 connections, the DN300 simplifies cable routing to the front derailleur and rear derailleur and provides continuous power at all times. The third connector is for those who want to keep open the option of a cabled version of SHIMANO's 12-speed Di2 systems.

PRODUCT SPECIFICATIONS:

• Compatible with the new, thinner SD300 power cables used on the R9250/R8150 series and up.
• 3 SD300 connectors

• Same mounting method as BT-DN110
