One way or another, the wiring of a windlass requires some hefty cables. But I would not put the battery in the nose for two reasons. First, there isn't as much room in the rode locker as you would imagine. I assume your Quick is a vertical windlass (like my own) and you need all the "drop" that you can get from the windlass to the locker floor to keep the rode moving downwards. Second, a windlass sucks up a lot of juice and I'm against having a dedicated battery for that purpose. I feel it's better to have two batteries and to switch them daily so as to have one in a fully charged state, in reserve, at all times and to use the house battery of the day for everything.
Good luck with the installation.
