I agree with Topwater Elvis's recommendations.
With regulated mods, coil resistance is irrelevant. What matters is the wattage setting that you will be using.
If you use a good quality 20 amp CDR battery like the Samsung 30Q, LG HG2, or Sony VTC6 then you are good for 60 watts per battery. If using a 2-battery regulated mod, your good for 120 watts as you have two batteries.
With the Sony VTC5A, you will be good for up to 75 watts per battery; 150 watts with two.
If you use a single 30 amp CDR battery like the LG HB6 you are good up to 90 watts; with a pair of 30 amp CDR batteries you could safely do 180 watts.

AW 18650 3000 mah 20 amp CDR
30W - 75W:

60W or higher:

LG18650HB4 1500mAh 30 amp CDR
Be skeptical of the spec ratings of any aftermarket battery (Efest, MXJO, AWT, Imren, etc). That would be anything not made by Lg, Samsung, or Sony. Aftermarket battery manufacturers exagerate their specs.
- Learn what a rewrap cell is. If you are using a rebranded or after market cell, does that mean it is inferior, poor quality, or even dangerous? Which batteries are suspected to be rebranded batteries.
