Shimano BT-DN320 Rear Derailleur Battery
Reliable, intuitive, consistent – the motto of the new Shimano XTR M9250 groupset says it all. Along with the return of Di2 technology in a wireless version, Shimano brings a compact and innovative power solution. The BT-DN330 battery eliminates the need for a wired connection to a central power source, significantly simplifying assembly and reducing weight.The small but powerful 305 mAh cell connects directly to the XTR Di2 RD-M9250 rear derailleur, where it is securely stored and simultaneously protected from weather influences. Charging is easy and fast – the battery can be easily removed without the need for special tools.

po nabití vydržala 253km, ale je pravda že kým som jazdil tak som sa s ňou občas hral a štukal hore dole. Isto minimálne vydrží 300km a viac

Samotná baterka vydrží pomerne dlhú dobu ale s náhradnou batériou na dlhšom výjazde sa nič nepokazí.
