We can't answer because you haven't specified how they will be wired. Four 6v batteries can imply a 24v system, or a 12v system with two sets of two 6v batteries. I'm going to assume you're talking about a 12v system (because of your second option), and will then assume that option 3 implies two 12v batteries wired in parallel. In that case, option 3 will provide the most run time (with 36 effective amp-hours) (I'm also assuming you mean "amp-hours" when you say "amp"). Option 2 comes in second, and Option 1 will give you the shortest run time with 24 effective amp-hours (this is ignoring factors such as how different setups will be affected by the discharge rate being spread over multiple batteries, which could work to even the playing field between options 1 and 2. I still think that for a 12v setup, Option 3 wins
