The resistance of the motor is a constant, so the only things that can change is volts and current which means that as voltage goes down so does current.

That means that a 6 volt 10 amp battery should last longer than a 12 volt 10 amp battery.

Motors aren't resistors.

This is the charging system I would recommend to meet all of your charging needs

only downside is that it requires an additional kayak to be towed behind you...

Right, motors are inductive, but the load can be considered resistive
