Crimping a cable is preferable compared to using solder, in the past solder was used but it has been found that it migrates up the cable and creates a brittle spot which will lead to failure. A good crimp will never let loose and will conduct better, using adhesive lined shrink tube over the area will insure a sealed connection. In the photo of the newly crimped cable it shows the inner cable has a gap between the insulation and the lug, this is not acceptable and will lead to corrosion.
Sometimes back yard procedures are less desirable.
