Cable lugs - crimp or solder
Biggest thing with using soldered lugs is to support and route the wire in a manner that avoids flexing at the solder joint. Vibration is the enemy of soldered connections because the wire is stiffened and becomes a bit brittle where the solder wicks into the strands.
The parts listed in jimro’s post seem to be quality stuff, and adhesive heat shrink would protect the wire from corrosion and vibration as well.
Personally, I’ll still crimp stuff, as I have the right tooling. Heat shrink gets added either way.
Just be sure to use good parts and techniques, and it should be fine.
Admittedly we’re not building aircraft or spacecraft around here. (But we can dream, right?)
