New battery designs and amp hours
What battery design has the most amp hours for its size in "deep cycle" type. Any of the "new" designs able to pack lots of amp hours in smaller size? I think I have a group 27 deep cycle that...

It depends on the shape of your space and your budget.
Unlimited budget: I think Li-ion batteries are the best (or among the best) currently available in terms of energy density. You'd almost certainly need different chargers, etc. to make use of them.
Modest budget: Golf cart batteries are probably about the best reasonable choices. 6V GC2 batteries (in pairs) are the most cost-effective. If you have the room, a pair of 12V GC12 batteries would have a greater capacity but be less cost-effective for the capacity. (GC12's are somewhat longer than GC2's, but about the same width and height.)
