This is a medium duty battery post / terminal. "Proper" automotive terminals where too much money, and I don't need to provide that much power. The little bench supply terminals were too light duty. So I made these.

The "post" is a 3/16 inch threaded rod. The hole in the metal is 3/8". I happened to have a couple special threaded rods with 1/4" nut built into the middle. I glued a 5/16" nut into the caps to thread them on. They should cover the post to minimize moisture.

I have located the RV battery for our tent trailer inside (where the water tank used to be - we never used the sink), however, I still need/want a way to connect solar, accessories, chargers, etc to the battery. The wires on the hitch were loose and always a bit concerning. I printed these in red and black and installed them on our hitch.

Forced myself to use OnShape to make this. I'm hitting the limits of Tinkercad and need to grow up a little.
