For dual mod, normal wattage between 60-65.

Which 18650's should I go with?

If you're truly not exceeding 65 watts, Samsung 30Q, LG HG2, and Sony VTC6 will give a bit more run time at 3000mAh than the higher amperage 2600mAh Molicels.
No. Most dual 18650 are built with a series connection. Two 3000mAh 20A 3.7V in series would yield 20A 3000mAh 7.4V. Two 3000mAh 20A 3.7V in parallel would yield 6000mAh 40A 3.7V. All of those numbers are great on paper, but do not take into account any voltage drop through the mod or atomizer or any wizardry performed by a regulated mod's board.
If you were running very low builds at higher wattages - say a .12Ω max mesh coil at 130 watts - you'd be far better off with a higher amp rating. Ohms law tells us that this configuration will take roughly 33 Amps. That's outside the continuous discharge (CDR) rating of any currently available 18650, but most regulated mod provides protections against any serious problems in that regard.
If you're running a higher resistance build at lower wattages - say a 0.5Ω coil at 60 watts - you're better served with a higher mAh rating for longer run times. Again with the ohms law... Only around 11 amps pulled.
There is an inverse relationship between mAh and Amps in LiIon cells. The more mAh, the lower the CDR, the higher the CDR, the lower the mAh.
At present, the best CDR is 30Amps at 2000mAh (Samsung 20s). The best mAh is 3000 at 20Amps (LG HG2).
As a general rule, any 15 Amp rated cell can be used up to 45 watts. Two 15 Amp cells up to 90 watts. 20 Amp cells up to 60 and 120. 30 Amp cells up to 90 and 180. For higher power, use 3 cells (like the Wismec Reuleaux line).
As you seem to be new to batteries, I recommend you Google "battery Mooch". Mooch is a battery tester extraordinaire and typically tests and post the results of said tests on the interests. He maintains a chart of all the latest and greatest batteries, too.
Crap.
These are rewraps. There are only a handful of LiIon battery manufacturers on the planet... Sony, Samsung, Sanyo/Panasonic, LG, Molicel (?). Anything other than these brands are lower grade cells auctioned off from one of these manufacturers. Theres are no rules or regs that I am aware of about how cells are labeled once purchased. So Master could've purchased 1500 mAh 5Amp batteries and slapped that ridiculous 3500mAh 35Amp rating on them.
Always buy authentic cells from a reputable vendor like illumn.com, liIonWholesale.com, or IMRBatteries.com to avoid problems. Note that eBay and Amazon are not considered reputable vendors, regardless of what the battery wrappers say... There are a lot of counterfeit cells out there.
Yup.
Awsome. Thank you.
i would have to recommend Sony (?) VTC5A or VTC6A (dunno where you could find 6As however) and LG (?) HB6 if you want a battery that can handle any build you can set up in an atty without worries about heat or other troubles one may find with weaksauce batteries.
note: the battery brand names might be switched or just plain incorrect, but the names of the type of batteries themselves (VTC5A or HB6) are correct and should be readily searchable online
hope you find what you need OP

Just use this calculation for regulated mods
Wattage/battery count/low voltage/mods efficiency
Example: Dual Battery mod @60w
60w/2=30/3.2(Low Voltage)=9.375a/.85(mods efficiency)= 11.02a = Any 15a CDR rated battery is adequate in this application
Certain things change in this calculation... low voltage setting... some mods have a lower setting or you can set that low voltage setting (Think Dicodes) and that will change the overall calculation.
Example 2: Dual battery mod @120w
120/2=60/3.2=18.75/.85=22.05a In this example of 120w usage, you'd want to utilize batteries with at least a 22a rating...
Example 3: Triple battery mod @120w
120/3=40/3.2=12.5a/.85=14.7a You could utilize a 15a battery again...but you're leaving yourself very little wiggle room in later stages of battery life...I'd use a 20a here
Now lets say you're using a DNA200 or one of the newer DNA250Cs, these have an efficiency rating of 97%
60/2=30/3.2=9.375/.97=9.66a
120/2=60/3.2=18.75a/.97=19.33a
120/3=40/3.2=12.5/.97=12.89a
TL;DR
Watts divided by battery count divided by low voltage cut off divided by mods efficiency = what battery you should use
Ohm's Law is not used calculating regulated mods
