Don't bother with expensive/exoctic cables - just get some decent 4sqmm
or 6sqmm flex, the longer the run the thicker. If the run is short (a
metre or two) then 2.5sqmm cable will do perfectly well. Go for a 79
strand or better if you can and don't pay more than about £1.50/metre.

Great to hear a man who knows his onions talk good sense.
