ROSE Bikes BT-DN300 Li-Ion Battery Di2 12-speed Integrated for EW-SD300| Electronic Shifting|Batteries And Rechargeable Batteries

Integrated in the seat post or in the frame, the powerful BT-DN300 Li-Ion battery provides the necessary energy for SHIMANO’s Di2 systems. The thinner E-Tube cables of the SHIMANO Dura Ace 9200 and Ultegra 8100 groupsets can be connected to the three SD300 connectors for road bike front derailleurs and 12-speed rear derailleurs. In addition to the two connections for derailleur gears at the front and rear, the third connection can be used for a cabled operation of the 12-speed Di2 groupsets.

With its waterproof design and slim dimensions, the DN300 battery, made of high-quality lithium-ion cells, can just disappear into frame and be well protected. If you want to insert the battery into the seat post, you need a battery holder such as the ROSE holder (prod. code: 1955576). The power storage unit is charged by connecting a EW-EC300A charging cable with a compatible USB charger to the rear derailleur.
