I want to be able to plug in external power while doing software updates or a battery tender without un-cowling the plane. My EarthX specific charger/power supply came with alligator clips for the battery, but it also came with a fused pigtail that has ring terminals on the battery side and a capped connector on the other.

I had previously installed this pigtail so I could tinker with the electronics without running the battery down, so I made that installation semi permanent by securing the plug via adel clamp to an engine mount tube where I can hopefully access it through the oil filler door.

I know some people are okay with zip ties for this kind of thing, but I'm not one of those people. I'll use zip ties in not critical applications or where something more robust won't work because of access or weight or whatever, and I have a ton of them on my plane . In fact, I used one to secure the service loop on this pigtail. But, firewall forward nothing beats white adel clamps for security and long life. If you want to secure something in a high temp environment and never have to worry about it again, use a white or blue adel clamp.

At this point, I've lost track of how many of these things I've used firewall forward, but there are a bunch.
