I've moved these posts (or portions of posts) here to start conversation about which batteries and box mods everyone recommends.....
I already own a Mighty, Volcano, and two little box mods I use for dispensary cartridges. Gotta find one with lower wattage though... the harsh hits are pretty rough, almost got sick to my stomach a few times.
What box mod do you have? My state just went med legal and I'm able to get some nice (but way too expensive) carts. I have a variable wattage Eleaf box mod and I can lower the wattage as much as I want. I'm not a mod expert but Eleaf or Joytech seem to be the Ford and Chevy of variable wattage mods (works well and not too expensive). I have this one which is a bit of overkill.....but it works wonderfully, IMO.

I’m nearby - cartridges here are expensive as well.
I have an Eleaf I Stick Mini - it’s 10w with variable voltage. Even at the lowest voltage setting (3.3 or 3.6, I think) it’s a little harsh. Maybe it’s just me though. I’ll take a look at a chart and see though.
