Description
Milwaukee M12 battery adapter.
-Mounting flange with inset for #10 hardware (I used 10-24). Flange is designed to be bolted from the inside, but I'm sure you could work hardware in from the outside if you wanted to.
-Through mount wiring. (I included a template in the print profile for drilling mounting holes and wiring pass through.
-#6-32X1/2" screws for backing plate.
NOTE: When assembling, I prepare the wires with spade connectors (no insulation on the connectors.) Install the spades into the adapter, and press a battery pack into the adapter to ensure spade alignment. Then I fill the end cap with silicone, and install. Leave the battery installed until the silicone sets. (Ensure your wires are taped and separated!)
