Shimano battery pack Di2 internal 2022

Note: Batteries are only shipped to AT/DE

Now with 3 connections, it provides stable power for SHIMANO's 12-speed road bike front derailleurs and rear derailleurs (when choosing a fully wired 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 offers continuous power at all times. The third port is for those who want to keep the option of a wired version of SHIMANO's 12-speed Di2 systems open.

• Compatible with the new, thinner SD300 power cables, which are used from the R9250/R8150 series onwards
• 3 SD300 connections
• Same mounting method as BT-DN110
