In theory, the cables between the two batteries only carry half the current that the cables to the inverter would carry (assuming two batteries in parallel) and are short enough that added voltage drop is fairly insignificant.
Well, yes, that's true IF you hook your + and - wires from the inverter up to the SAME battery. Personally, I would hook the + wire to one battery and the - wire to the OTHER battery to keep the load on the two batteries balanced. For that, you want the battery to battery cables to be the same size as the inverter wires.
But as a practical matter, either way would work.
