5AWG (16mm2) cables, short length (Woodingdean)

I can make very good use of a pair of 5AWG (16mm2) cables for connecting a 600w inverter to a car battery, in order to do some voluntary work. A short length would be good - between 30cm and 100cm. If you have a spare unused set, I'd be so grateful for them - thanks in advance! I can collect to suit you.
