External mount for Internal battery

SM-BTC1 - External mount for Internal battery image

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:

You can use it with both SM-BTR2 (previous internal battery) and the newer BT-DN110 battery It uses 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 last point is important. The SM-BCR2 also lets you connect your bike to a windows computer to change settings. The 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.
