I was at my LHS today and they showed me this set up that the aircraft guys are using to turn the power on and off with instead of using a switch that could get accidentally tuned off. It is a base mount that holds a female DEANS plug and is wired in line with the positive side of the battery. To arm the plane the use a male plug with the wire ends connected together and just plug it into the base for a quick and solid way to connect the power.
I think this will make a great charging port for a truck or a good plug to mount in a deck plate for a power outlet for any trailer needing a power supply like a dump trailer.
It is made by SCHUMACHER PRODUCTS LLC.

I don't see us really needing the arming plug but thought I would include it so you know how it was intended to be used but the members here on the forum are always using stuff for other purposes than what it was designed for.
