SHIMANO Lithium-Ion Battery for Di2 12S BT-DN300 internal - Black

The DN300 battery has the same dimensions and mounting method as its predecessor. New are the SD300 connectors for the latest generation of Shimano E-Tube cables. These cables power the front and rear derailleurs of the Dura-Ache 9200 and Ultegra 8100 groupsets. In addition to the two connectors for the front and rear derailleurs, a third connector can be used for fully wired operation of the new Di2 groupsets. The
battery, consisting of two high-quality lithium-ion cells, is charged via a charging port integrated into the rear derailleur. Its cells offer high capacity, providing approximately 2000 km of range with numerous shifting operations. The lithium-ion technology allows the battery to be used in a wide temperature range of -20 to 60°C, making it suitable for use in any season.
