I get about the same life as dual 18650's or a little less on my VT200 that also has 3 1300mAh lipos. From the amount you say that you vape, you should get a full day of vaping on a full charge. If you need battery life then I would recommend the Reuleaux DNA 200. It is my only Mod that will last me all day without a battery change. I also have the VT133 that has dual 18650's so if I need extended battery life, I just take a couple extra 18650's with me.
