External mount for Internal battery
Non-series components SM-BTC1
If you cannot place the BT-DN110 Internal Battery in your bike's frame you have two options: either use the BM-DN100 external battery mount and the SM-BTR1 battery, or use the SM-BTC1 external mount for the internal battery. In most cases using the SM-BTC1 is the better option. It has several advantages:
The 12-speed BT-DN300 is not compatible.
The SM-BTC1 has a low profile design and attaches to a frame's bottle cage mounts
You can use SM-BCR2 to charge the bike instead of SM-BCR1
The SM-BCR2 also lets you connect your bike to a windows computer to change settings. The external battery charger, SM-BCR1, does not.
It features 6 E-Tube ports (SD50) with a cable organizer - it functions as a Junction B. One of these ports is used to connect the battery.
