Ralph's picture reminds me one technical option.
If you want reliable high-amperage 12V quick connection, use electric forklift plugs.
They come with couple of sizes and can be rated for 400 amps.
Basically idiot-proof in usage and silver-plated prongs last long time.
Crimping the connectors might be hard as it require special and expensive press, but what I was doing for my winch was hammering the end of connector flat, drilling a hole and using short bolt connecting a cable with eye connector on the end.
Brass or SS bolt makes it lifetime set.

require special and expensive press?? I always used solder in the past. I would hold the connector end vertically in a vise have wire stripped and ready. Heat the end with a propane torch and fill the hole with solder then just stick the wire in.

I've been soldering connectors as well, but I do have plumbers torch, that cost money as well.
Also from your description you did not clean and flux the wires in the cable. That will make for cold solder.
