The BM-DN100 Di2 battery mount by Shimano enables wireless communication

The Shimano Di2 battery mount BM-DN100 is much more than just a mount - as a master unit it has Bluetooth and thus establishes a wireless connection between a separately available wireless unit (e.g. SC-MT800, EW-WU101) and a tablet or smartphone. This is perfect for quick adjustment on the road or for detailed analysis in the workshop. BM-DN100 was specially designed for the external battery SM-BTR1, which (unlike BT-DN110) is not Bluetooth-compatible itself. There are three different versions: a long mount for external cable routing, a long mount for internal cable routing and a short mount for external or internal cable routing. Mounting material is supplied.
