Three different mounts for Hilti B22 batteries
Vertical model does not clip, and is shorter. Can totally be used horizontally for stationary purposes.
Horizontal models do clip on, and were designed to be placed in a van. So they wouldn't slide out in corners.
The thick model has an added 15mm top, for better access to the clip. The slim version should be mounted along an edge, so the clip on the battery is reachable.
