If your looking for battery life, look at a NLPWM lipo box. I have 2 boxes I built with a 2800mAh 4s battery and that will last me 2 days on a single charge (takes about 1/2 - 3/4 an hour to charge depending on how dead it is). My other box I run a 4000mAh 3s (last me 2 1/2 days at the least and up to 3 days and 2 days on my days off when I'm chain vaping and takes that one an hour to charge completely). I have a 40mm Mason RDA on one and my 41mm Voltrove RTA on the other so when I'm feeling the juice in the tank I'll vape on it but I'm not the kind of guy that has an ADV (since I DIY I have so many favs I can't vape on one all day usually).
I vapes on a HOG V3 (quad 18650) and unregulated mods I build (dual 18650) and would run through at least eight 18650's a day on my HOG (which I was usually vaping on) and if I had to run errands after work I would have to take 12 batteries with me and I would spend all night from the time I got home till the time I went to bed charging batteries and that was just for a single days use. Now I don't have to worry about it and I can charge 2 days of use on a single battery. I absolutely love it! I will NEVER go back to carrying around 18650's. Don't get me wrong, I still use the mods (just picked up the HOG and threw a 30mm RDA on it (had to build new coils and wick it) and used it.
I didn't ever realize how long the ramp up is on 22g Kanthal (I used to use SS but got into using Kanthal because of having to build to at least .3 (you don't want to build low on the lipos. I usually build about .4 at least. I've built a dual 18g Kanthal to 1.2 and had no ramp up time). I can have an alien coil 6 wraps on a 5mm and have very little ramp up. On a 18650 mod that would take forever just to heat up.
If your looking for long battery life on a single charge, def look up lipos. If u know how to solder and want VV, you can pick up a NLPWM kit for $125 at either Voltrove's website or Friendly Fire Mods website. They work together. If you want VW then get their DNA250 kit for $150. If you don't know how to solder, you can pick up a mod already built or choose your own mod, color of acrylic doors (or they have 3D printed boxes for kits or already built mods), buttons, battery, LED's inside the box if you want them and voltmeter or readout color.
