SHIMANO BT-DN320 Di2 Battery: The Heart of Your 12-Speed Electronic Drivetrain
Experience the pinnacle of electronic shifting performance with the SHIMANO BT-DN320 Di2 Battery, the central power source engineered for Shimano´s revolutionary 12-speed Di2 road and MTB groupsets. This built-in battery is the silent, reliable engine that drives the flawless, instantaneous gear changes you demand, ensuring your drivetrain is always ready for the next climb, sprint, or technical descent. As the core of Shimano´s latest wireless-enabled systems, the BT-DN320 represents a leap forward in integration, longevity, and reliability for the modern cyclist.
Key Benefits
Unwavering Reliability and Protection
Engineered as a “Battery Built-In Type,” the BT-DN320 is designed to be securely housed within your bicycle´s seatpost or, for MTB applications, directly inside the new wireless XTR rear derailleur. This integrated design means the battery is exceptionally protected from the elements, impacts, and vibrations. Tucked safely inside an enclosed space, the battery won´t budge even on the roughest singletrack or harshest cobblestones, providing a stable and consistent power supply for unwavering shifting performance when you need it most. Despite its protected nature, it remains completely removable for charging and maintenance.
Exceptional Longevity for Extended Rides
Spend more time riding and less time charging. The BT-DN320 boasts a high-capacity 310 mAh lithium-ion cell, offering an impressive lifespan that supports thousands of kilometers of riding on a single charge. This exceptional longevity translates to worry-free performance, allowing you to tackle epic multi-day adventures, long training blocks, or an entire race season without battery anxiety. The power to perform is always on tap.
Streamlined Integration and Simplified Charging
The advent of full wireless technology demanded an all-new battery, and the BT-DN320 delivers. By acting as the central power hub for both the front and rear derailleurs (connected via thin SD-300 wires), it dramatically simplifies the Di2 system, enabling a cleaner, more aerodynamic, and lighter build. Charging the system is more convenient than ever, typically accomplished via a charge port directly on the rear derailleur, eliminating the need for separate junction boxes and making it easy to top up your power.
