Internal Battery Mount Kit for Scalpel-Si. This kit includes all of the necessary hardware to mount the Shimano Internal Battery into the top tube of your Scalpel-Si. It also includes new cable fittings and all of the necessary hardware. You could also (potentially) use this to mount an internal Di2 battery into other frames as well. We have done so on older scalpels, as well as in the downtube of other bikes.
