Nobody can answer you, because it depends on your design. It also depends on alloy you are using - kanthal or nichrome.
Anyway try 32-34GA. Most common wire. I would recommend 34GA

As far as solid or stranded it really doesn't matter at low voltages. High voltages solid wire wire the electrons tend to run only on the outer part of the wire, skipping the inter or core of the wire. Something we dont have to worry about. Stranded wire is alot easier to work with as far as bending so thats what i like to use.
I use the absolute biggest wire gauge i can fit into my mod. Bigger the wire the less resistance which results in a more efficient mod . I wont use anything smaller then 24gauge wire in my Mods.
The first two posters are talking about atomizer coil wire which i am pretty sure your not asking about. That would have to be solid wire

For 2 batteries mod? Hahaha, did you try this ever?

The first two posters are talking about coils the TS asks. He wants 2-bats mod. It's highvolt. So he could consider high resistance of his heater. I don't think that on 7 volts any atty with 24 GA will work fine
Anyway you could try

I was confused about that too. Sounds like he's asking about wires running from the battery to the atomizer.
You could probably get away with 26 AWG if your wires are short enough, but I wouldn't go that fine unless I really had to. I tend to use 22 or 20 gauge whenever possible. 18 gauge is not out of the question.
You can look up wire resistance easily enough and determine how much power you're going to lose in the wiring. For example, 26 AWG has about 40mΩ per foot. If you use 6 inches to get to the battery and back, that would be a power loss of 80mW at 2A. Compared to the 7.4W of the load that would be a loss a little over 1% in the wiring. Probably acceptable, but you could quarter that by using 20 AWG wire. Also, resistance goes up considerably with heat and the smaller wire is going to heat up faster. Power loss goes up considerably with heat as well.
I like solid wire a lot since I find it easier to work with. I'm not sure if the electrical properties are better or worse, but you can figure a cross section of solid wire contains more copper area than a cross section of stranded wire.

I use nothing but 20 or 22ga. Anything higher usually has a poor strand count and lower is often too thick to work with in small mods
Since you'll likely have your positive and negative battery terminals close to your regulator, you could get away with 26 AWG. Also, for a buck regulator, input current is lower than output current so that further reduces losses in the wiring from battery to regulator. Even so, my limit would be 24 gauge, especially for the atomizer since currents would be higher. I'd be perfectly comfortable using 22 AWG throughout a mod like that.
It's good that you asked this question. When I made my first mod, I went to radio shack without the knowledge. I came away with a boat load of 18 ga, and it was a pain to work with. it works if you don't need to go around any corners with it. do yourself a favor and use 20-22 like most people said.
