A tale of battery cables

BTW, the conductivity of solder is right around 1/10th that of copper.

That is true!

Silver is more conductive than copper, the heat it takes to solder would increase the temperature related issues. It is hard to beat a good crimp.

Here is a link for a list of materials resistivity and conductivity.
