Shimano BT-DN320 derailleur battery

Reliable, intuitive, consistent – ​​the motto of the new Shimano XTR M9250 groupset says it all. With the return of Di2 technology in a wireless version, Shimano is bringing a compact and innovative power solution. The BT-DN330 battery eliminates the need for a cable connection to a central source, which significantly simplifies installation and reduces weight.
The small but powerful 305 mAh cell plugs directly into the XTR Di2 RD-M9250 derailleur, where it is safely stored and protected from the elements. Charging is simple and fast – the battery can be easily removed without the need for special tools.
