The Standard Battery Mount Shelf includes holes specifically placed for BionX and Neodrives batteries, as well as holes placed at bottle-mount spacing to accommodate downtube batteries (as well as some bonus holes for attaching to the Adapter Shelf).
The ICE Shelf cannot be directly attached to the ICE Rear Rack.
Combined with the other battery components you have much flexibility to adjust the battery. In my case the battery was under the seat and was hitting the seat cross bar. I was able to adjust the angle of the and height of the plate so it cleared the seat. Another excellent product by TerraCycle.
Didn't work for what I needed it for but I am sure it will be great on the right bike
I do not have it as one yet.
