The BT-DN110 battery by Shimano - wireless function for your Di2 drivetrain

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.

Absoluter Schrott, zumindest am MTB. 2 Akkus wurden auf Garantie getauscht, der nunmehr dritte Akku lässt sich nur noch zu maximal 40% der Gesamtleistung aufladen.....Akku Nr. 3 steckt dabei gut verpackt/geschützt unterhalb der Sattelstütze im Rahmen. FAZIT: Was am Rennrad durchaus Sinn macht, würde ich am MTB nicht mehr verbauen, da sollte man die Finger von elektronischen Systemen lassen. So nebenbei: Auch ein Servomotor der XTR Di2 Schaltung hat schlapp gemacht, ebenfalls Garantieaustausch......

Habe die Batterie als Upgrade für meine Ultegra 6870 gekauft. Incl. der Wireless Unit kann damit das Syncro-Shift nachgerüstet werden. Akkulaufleistung top regelmäßig > 2000km mit einer Ladung.
