Udit, can I just say (and others will be along) that you may not want to start vaping at 120 W if you are at 4--5 cigarettes per week, just because it looks like you want to jump straight into sub-ohming which would be fine, certainly, and I'm glad you are worried about your battery safety, but that's a LOT OF WARM/HOT vape right there, and I'm assuming you'll be wanting at least some nicotine in your vape? If you want to go to 0 nic, then maybe that might work?
But starting out with those target numbers I am concerned that you might easily O'D on nicotine in just a few puffs, and also, you are getting something pretty advanced when something smaller/lighter/less expensive and more like smoking (mouth-to-lung rather than direct-to-lung) might fit you better to start?
You can check out Mooch's blog on battery safety to determine what batterie(s) you might need, but ah, I am just a bit concerned that you might be overdoing it on the vape, to start.
I have never vaped over 50 watts in my life, and I was a 3 ppd smoker. I prefer hanging out in the 8--12 watt range.
That said, if this is your plan, far be it from me to dissuade you, but do look at the pinned threads on nicotine o/d sx vs. cigarette w/d sx, in the new members forum, so that if your vape is a bit much, you'll be able to identify what's going on.
Best of luck,
Anna
