The Shimano BT-DN320 is a next-generation Di2 battery designed to power the wireless rear derailleur system. It provides consistent energy delivery to ensure smooth, precise shifting, even under heavy riding conditions.

Protected Internal Placement: Housed securely inside the rear derailleur, the BT-DN320 battery is protected from external impacts, debris and weather. Its snug fit ensures that it remains stable on rough terrain while still being fully removable for charging or replacement.

Long-Lasting Performance: With a 305 mAh capacity, this battery is built for endurance. Riders can enjoy extended usage time between charges, making it reliable for long training sessions, races, or multi-day rides without worrying about power loss.

Ease of Maintenance: Despite its protected location, the battery is designed for easy removal when needed. This allows straightforward charging and replacement while minimizing downtime and keeping your drivetrain in peak condition.

The BT-DN320 is fully optimized for Shimano’s Di2 wireless platform. It supports fast, stable connections between components, enabling quicker shifts and better overall system responsiveness.
