| I don't think anybody has already said this: I have always used two batteries, but I have the boat wired so that things that draw a lot of power, like the trolling motor or pumps go to one battery, and the other is wired to the starter and electronics, which don't use much. That way if I ever run the one down with the trolling motor or run the bilge pump a lot on a rainy day my starting battery will always be good. The only draw back to this is that the second battery doesn't get recharged by the engine while running down a lake. But I've always been OK with just putting a charger on the second battery at the dock | |
