I have been vaping for about a year but I never looked into what battery is were best because I just always used home life. But now i have a single battery mod (tvl revanant delta) and it's my favorite mod so far. But it does so quickly with a single 18650 hohm life. It can take 18650/20700/21700. So I'm looking for a battery that will last longer and still hit nicely I normally vape around .09 at 75watts. I dont know wich of the three types are the best so I really need some advise on wich 3 sizes and wich battery is in those sizes are best for me.
