Recommended batteries for 70W reg mod for sub-ohm?

[Johnivan69]

Greetings,
So I'm getting my head wrapped around Ohm's law, but I'm still at a loss for battery codes. From what I understand, I need at least a 20A battery (18650) to have a good safety margin for my new regulated mod. That being said, what the heck is the correct battery?
I'm looking at RTD's website, but I keep getting lost with all the numbers and maH numbers.
Your advice and help is always appreciated. It's all about safe vaping...

To run 70 watts you need about 25 amps when the battery is almost fully discharged which is when it sees the most amp drain. Atty resistance does not matter because you set watts which is the same no matter what resistance your build is. The only batteries I know of that are rated for that are the Sony VTC series. You can get VTC4's from RTD Vapor for $11.27 a piece. There is no supplier that I know of that is selling authentic VTC5's right now.
