Shimano BT-DN300 Di2 Battery (2nd Gen.)

Thanks to its compact design, the Shimano BT-DN300 battery can be easily installed in the seatpost or frame. In addition to a smaller design compared to the previous model, the battery’s waterproofing has also been improved. It features a three-port connection for the front and rear Shimano Di2 derailleurs. Tested with the latest Shimano Di2 Ultegra (8100/8150) and Dura-Ace (9200/9250) 12-speed groupsets, it ensures an average of over 1,000 kilometers of riding.
