Battery base for Milwaukee M12 batteries. Thru-holes allow wire to be passed through, and spade lugs crimped on, and pushed through the bottom so that they obtain 12V from an M12 battery when seated. Once everything is in place, the intent is to back-fill the cavities in the bottom with epoxy, or similar to keep the connections insulated and hold everything in place.

The model features two mounting "ears" as well.
