The Shimano BT-DN300 Built-In Type Di2 Battery is engineered to deliver consistent and reliable power to Shimano's latest 12-speed Di2 systems. Its internal mounting design ensures a clean look and seamless integration with modern road bikes.
Three-Port Configuration for Flexible Wiring: With three SD300 ports, the BT-DN300 makes it easier to wire both front and rear derailleurs while also supporting a fully wired option. This added flexibility allows riders to configure their Di2 setup for maximum efficiency or redundancy.
Waterproof and Durable Design: Built with the same waterproofing Shimano users have trusted for years, this battery maintains performance even in challenging weather conditions. It ensures long-term reliability and durability for high-performance road riding.
Slim Profile for Internal Mounting: Sharing the same size and fixing method as the previous BT-DN110 model, the DN300 fits neatly inside seatposts or frames. Its compact shape supports a clean aesthetic and protects the battery from external wear.
The Shimano BT-DN300 is fully compatible with the thinner SD300 electric wires and is specifically designed for use with systems from the R9250 and R8150 series onward.
