Shimano BT-DN320 On Components Type Battery
Shimano BT-DN320 On Components Type Battery Info
The Shimano BT-DN320 On Components Type Battery sits inside the rear derailleur itself — keeping the drivetrain clean, protected, and free of external wiring. Designed for Shimano's wireless groupset systems, it integrates directly into the derailleur body rather than routing to a separate battery port elsewhere on the bike.
With a 305 mAh capacity, the BT-DN320 is built to deliver extended ride time between charges. When it does need charging, the battery is removable — slide it out, charge it, reinstall. The enclosed mounting position keeps it shielded from trail debris and the elements, so the power source isn't a weak point in demanding conditions.
