Shimano di2 BT-DN300 internal battery

The new DN300 battery offers the same waterproof structure that DI2 users have loved for generations. Now equipped with 3 doors, it provides a stable diet to the anti deraillers. And to 12 -speed road changes Shimano (with the option completely wired).
With the same sizes as the previous model, the thin DN300 battery can be housed in the bra or frames, ensuring a clean aesthetic.
Equipped with 3 doors now, the DN300 model simplifies the wiring to the front and rear deraillers, providing a stable diet.
The third door is for those who want the redundancy of the Bimano di2v wired option. The battery is compatible with the more subtle generation of the new generation SD300 and with the systems following the R9250/R8150 series.
