BATTERY SHIMANO DI2 INTERNAL BTDN110A1

The Shimano BT-DN110 Di2 battery is designed for internal mounting in the seatpost (external mounting optional) and has another central function besides the power supply of the Di2 drivetrain as a battery: it also functions as a Master Unit and is Bluetooth-enabled and thus establishes a wireless connection between a wireless unit (e.g. SC-MT800, EW-WU101, not included) and a smartphone or tablet. This is perfect for quick adjustment on the road or for detailed analysis in the workshop. Via the E-Tube platform you can keep the firmware of the battery up-to-date.
