What's the highest wattage you are planning on using? That will determine the CDR (continuous discharge rating) of the cells you need to purchase.

The best way to determine how many amps you will be drawing (at minimum battery voltage) is to use the maximum wattage you plan on vaping at and follow this guide.
Once you determine your amp draw see @Mooch's list of recommended cells.
Only buy batteries from a reputable supplier (not ebay or Amazon) as there are many counterfeit batteries being sold. Here are several reputable battery suppliers in the US.

As asylumsix said, within that range I would also recommend the HG2's.
The VTC5's are great batteries, the HG2's would simply provide longer run times.
Once I tried them, I now use them pretty much exclusively.
And as susan~s recommended, I use RTD Vapor exclusively and can't recommend them highly enough. Always authentic. Great customer service. Fast shipping. Good prices.
They even offer a discount for ECF members with code "ecf5", and include free battery cases if you order in pairs.

Don't think temp control and battery matters

The best batteries matter full stop

Always go for a reputable battery

Lg hg2 he4
Sony vtc4/5
Samsung 25r or 30q

Those are what I use in all my miss be temp control or not
Not too sure.
I'm right now running at 480, it's pulling 12 amps momentarily. This is a Cuboid dual battery, I believe that would be 24 amps on a single battery. So yes, batteries on temp control still matter.

Put that same theory in to a series mod and a tube mech then yes

Regulated device hmmm not sure

Agree.
I'm running 25r's &HE4's on my regulated mods. Save my VTC4's for my mechs.
Rather be safe than sorry. And I keep my cheap flashlight batteries of unknown specs for my flashlights.

Bear in mind the Cuboid is a series mod, so the with two batteries you are getting approx. "double" the voltage output but your current or amps remain the same as the rating of one battery alone. i.e. 2 20amp batteries at 4.2 volts will output 8.4 volts, but still only at 20 amps.

Thanks for the correction Ranger!

All good recommendations here. The way that I "choose" a battery for a mod is by math.
Steam engine's "Ohm's Law" tab is great for that. Keep in mind that in a regulated mod, the resistance of the atomizer is irrelevant, the circuitry is going to pull the required current out of the battery to "make" the desired power.
For example, let's say that you want to send 50 watts to your atomizer, and the low voltage cutoff for your mod is 3.1 volts.
Power = Voltage X Current. You know the power and the voltage, and solving for current gives you 16.1 amps. I'd be happy with a good 20 amp battery in this case.
And to add another battery to the mix, AW has a relatively new 18650, 3000 mAh and a CDR (Continuous Discharge Rate) of 20 amps. That's really pretty good, considering the capacity of the cell, and they're also rated for >500 cycles, and that's darn excellent!

And being a regulated mod, whenever the voltage of the batteries drops below what the output of the mod is it compensates by drawing more current (amps) to convert into voltage. Therefore, you must leave a safety margin when choosing batteries. Therefore, of you are using a 1 ohm coil at 75 watts, mathematically you would be using 8.66 volts at 8.66 amps. In reality you are drawing more than 8.66 amps because if your batteries are at 3.7 volts each (7.4 total) the mod will draw more amperage to compensate for the voltage difference. How much more amperage will depend on the efficiency of the chip. Every mod will be differnetnt, so factoring in a safety margin is a must.

It can get very complicated. o_O
