I know a lot of people love the bloogs but, as far as I'm concerned, if I have to change a battery more than once in a day of heavy vaping without being plugged in, it's not for me. Just an opinion. You can't do that with anything that resembles a cigarette.
However, the advice on switching (You aren't quitting.), will work with what you have in mind. First off, you could be one of the lucky ones. You might start vaping and never look back. If you aren't, don't dispair. Remember every cigarette you don't smoke is a victory. I had 3 or 4 cigarettes a day for a few weeks after I started vaping. If you do that, don't do anything else while you are smoking. Notice how it tastes and makes you feel. It takes a few weeks to find your right nic level anyway. After a few weeks, you probably will find you don't enjoy it all that much. Then the step to vaping alone is pretty easy to make.
