of course, but ive seen a lot of batterys in the boot with the same size wire for the starter. Anyone can start a fire or melt things, but i tend to let common sense pervail most of the time. Most arc welders dont use thicker cable than the described and they can be 20 meteres long with no problems, at 300 amps
