    Darn straight. As I pointed out, there's good reason it's actually illegal by the electrical code in most places. I've had one battery explode on me outdoors (it was on my boat lift). I was just lucky I wasn't standing over it when it went. My jeans were sprayed with acid however and despite being washed fairly quickly there after ended up looking like swiss cheese. The thing was like having someone fire a gun next to my head (in fact, two of my neighbors thought that another was shooting at something...again).

    It should be noted that the installation example above assumes a battery "Maintainer" specifically designed for the battery being maintained will be used.
    I too would not ever use a battery "Charger" in a confined space, as has been mentioned.

    Yeah I have an Odyssey battery so I'm not sure a Battery Minder would be good for it.

    The Odyssey charger goes into maintenance mode once the battery is charged. Not sure how that's different from a Battery Minder System.

    This could be mounted flush to the skin, though best to use an offbeat socket like mine so folks don't try to recharge their phones at fly-ins.

    However, it would be prone to pick up dirt and grease. I've got an unwired plug sticking in mine to keep the crud out. It's the round part at the top of this picture. The socket is surrounded by a rubber grommet, with the blank plug sticking out in the middle.

    Hi Ron,

    What is the wiring behind the connector? Wire directly to the battery? If so, what gauge did you use?

    Thanks!

    Yep, directly to the battery. Don't know what gauge it is, but guessing 12 or 14. It's a very short run as the battery is above the big light-colored inspection panel. right near the front.

    Use a male plug and a scocket with a spring loaded lid for a powerwinch. Get both at any good auto store or marine store. Made for 12 volts and polarity keyed and will easily handle the needed current.

    Is much easier to install.

    Best of luck,

    Hello Wes,

    These look good. One question:

    There seems to be hold down the centerline. Are they to hold two halves together? Or can they be used to mount the connector on a bulkhead?

    thanks!

    Hi Ron,

    Thanks for the reply. Did you put an inline fuse in the line to the battery?

    Is your installation intended for battery top-off/maintenance charging? Or for full recharging?

    Thanks!

    There's no fuse. I didn't build the airplane, so I don't know what the builder's intent was, but the existing wires should be good to the ~6 amps an automotive-type charger supplies. One year, my generator was bad, and I kept the battery charged via this port.
