What are you doing that you need two batteries?
For the high-current wiring between batteries, it's a good idea to put fuses on both ends in case you have a short in the middle of the big cable between batteries - with one fuse, one of the batteries would not be protected.
Theoretically, each battery will supply half of the current. Of course, in the real world, it usually doesn't work out that way but, with the proper size wiring, shouldn't be too far off.
