As some of you know, I use an electric winch for launch and retrieval of the boat. It is a bit of a pain carrying an extra battery around though ( my battery was terminally damaged when assisting retrieval of a mates boat, so I need another one anyway), so I was thinking of using the Landrovers battery to power the winch. This requires running a cable from the battery to the back of the Landy. I will be using a battery isolator switch under the bonnet together with a fuse, with anderson connectors at the back. What I would like to know is, has anyone done this before me? If so what size cable did you use? and anybody know of somewhere I can get cable at a reasonable price? I was thinking of using 3 or 4awg cable (6mm or 5mm diameter of actual wires) from battery to anderson, or would this be too small/ I do have some cable that is 8mm diameter, but it seems very heavy to me.
