You need to use ohms law to calculate what the amp draw for your build is then choose a battery with a CDR that exceeds that value.
I = amps V = volts R = resistance P = watts
To find the amp draw use I=V/R
divide 4.2v by 0.3Ω = 14 amps
divide 4.2v by 0.19Ω = 22.1 amps
The Samsung 30Q or the LG HG2 would be good choices for the first build as they are both quality 3000 mAh cells.
For the hotter build the Samsung 20R or the VTC4 would be good choices.
You can use the chart below or read up on Mooch's blog to make educated choices when buying batteries.

How do I calculate the watts there ?You need to use ohms law to calculate what the amp draw for your build is then choose a battery with a CDR that exceeds that value.

To find the wattage use P=V²/R
Eg. 4.2v multiplied by 4.2v divided by 0.19Ω = 92.8 watts
Or use steam-engine, it's a one stop shop for vape relate maths
The short list:
For builds .21 and above*: Samsung 25R (20A discharge rating, 2500mAh capacity)
For .18 and above: Sony VTC4 (23A, 2100mAh)
For .14 and above: LG HB6 (30A, 1500mAh)
*(These are the minimum build limits to stay under the tested amp rating at full charge of 4.2v, with zero room for error. Inexperienced users should keep their builds well above these figures, to leave themselves some "headroom.")

Why use a Samsung 25R?
The LG HG2 and Samsung 30Q are both 20A batteries, and both of them have 3000mAh rather than the 25Rs 2500mAh. Since all 3 can handle the same 20A why would you use the battery with the least mAh?
And why use the 23A Sony VTC4 at all when the Sony VTC5A is 25A and higher mAh?
