Thanks to its compact dimensions, the flat Shimano BT-DN300 battery can be integrated inconspicuously into the seatpost or frame. Not only in terms of dimensions, it is similar to its predecessor BT-DN110, but also concerning waterproofness, it is in no way inferior.
The lithium-ion battery features three SD300 ports for the connection to front and rear derailleur. The third connector is used in the case of a fully cabled Di2 groupset.
In-house tests with the components of the current Dura Ace R9200/R9250 and Ultegra R8100/R8150 12-speed series have shown that the battery provides a powerful and stable power supply for the powerful actuators of the rear and front derailleur over a range of 1000 km on average.
