A tale of battery cables

KitCarlson, pardon me if I missed this, but how do you prevent corrosion from getting started between the crimped metals?

I admit that I am probably biased because I've been soldering since I was a kid, and maybe I inhaled too much lead vapor and flux fumes, but IMHO soldered connections are peachy keen.

Solder works for low current electronic connections that are well mechanically supported. High currents and solder, a completely different thing. Some solder fluxes promote future corrosion, not prevent it. I am not unique in my experience and knowledge.

The lug, is a copper closed end barrel. A good crimp is air tight. Heat shrink was used to enclose the lug and cable insulation.
