BT-DN300 Di2 Battery
$264.99
The DN300 battery maintains the waterproof design trusted by Di2 users while providing stable power to Shimano 12-speed road systems. Its slim profile allows it to be housed inside seat posts or frames to ensure a clean bike aesthetic.
Now featuring three ports, the DN300 simplifies wiring to front and rear derailleurs. The additional port offers a fully wired option for riders seeking maximum redundancy, making it compatible with the next generation SD300 electric wires.
