The Triade is a great box. The 3X30Q are more than sufficient for 100W. Remember, Watt's law applies on regulated mods. But the simplest back of the napkin calculation is a 20A battery should be good for ~60W each, allowing for board efficiency. I use 25Rs, which are also 20A but only 2,500 mAh, unlike the 30Qs which are 3,000, and would have no issues taking it up to 100-130W on that without a worry.
