Battery charging with cowl installed.
With an EFIS in the panel, I need to perform regular software upgrades, upload maps, plates etc. Keeping the battery charged when your only access to it is through the oil door is not ideal. I'm considering mounting a pad close to the oil door and connected to the plus side of the battery. It would need to be well insulated when not in use, but would make the process of charging the battery much more convenient. Has anyone done something similar with photos of their setup?

If you buy a "Battery Tender", they come with an insulated plug you can attach to the battery or "hot" side of the master solenoid. Just keep it "twist tied" close to the oil door and you can use it when needed.

I have a fuse protected "always hot" 12v outlet in the cockpit that I use to trickle charge at <2A when/if necessary.

I did this as well, both for use while working on the aircraft as well as for charging phones etc. in flight.

Tied to the oil filler neck
I also installed my tender plug inside the oil door by tie wrapping to the oil filler neck. That way the canopy stays closed.

Another one here with a 12v outlet (cigarette lighter socket) in the panel that goes straight to the battery thru a small fuse.

Battery charger plug
My battery is aft mounted complicating matters a bit. However I also have a reverse NACA duct for air outflow on the belly aft of the battery. At the time installed the charger wire all I had in stock was a 9pin Sub-D connector, so I used that, mounted inside the NACA duct. I attached the mating connector to the end of the battery maintainer cord. The nine pin plug allowed the connection to include the thermocouple wire, too. (My battery maintainer uses a thermocouple to prevent overheat of the battery.) When I have time for a do-over, I will use an AMP connector for a more secure connection.

I installed an "accessory plug" inside the oil filler door; adeled it to the engine mount x-bar. It's only about 10" from the battery, so the wiring to the terminals is very short. My Odyssey Optimizer plugs into it. I got the idea from Dave Burden's 9A.
