Yes Mickeyrat - that works perfectly for people who are near power most of the time. And standard size KR8 D2 and D1
batteries are 280mah, not 90 or 180 like smaller slim ecigs. The KR8 D1 and D2 are also 3.7 volts devices. I don't take well to contests over battery size and voltage. You have a big battery. I am happy for you. Everybody has different needs.
Re E9 - one downside is no manual
batteries. Manual KR808D-1 batteries aren't sealed on the end but at least they aren't dependent on a drag sensor in there. Once you start filling and refilling cartos, there is a definite chance you will end up killing one or more of your auto batteries because no matter how careful you are with refilling, occasionally a carto is going to drip out that bottom hole, right where your drag sensor is. Auto batteries can also turn on accidentally sometimes from wind or vibration. And they are more work in my opinion.
