I have soldered around a half dozen cables. In fact I have been for the last week charging my Mercedes B at 32A with an OpenEVSE and Blink cable combo to burn in the unit. Phil Childs has also soldered his cable.
It does take flux in addition to solder. Only one was burned and that one took scraping the wire bright first. If you have experience soldering it is certainly possible. Since there is several inches of cable in the handle stiffness is not an issue.
