20v DeWalt Battery Mount

The scaling for the battery mounts that are attached with screws was way off, so I've adjusted it to be the proper scaling. No need to scale it in your slicer anymore.

These will also work with the 60v FlexVolt batteries because they are attached to tools exactly the same as the 20v batteries.

Here are links to mounts for the tools:
