apparently IMR batteries won't fit in it, you have to use ICR ... IMR's tend to be just a little thicker than ICR.
on a related bonus note - discount vapers has them marked down to $48 while they last, and he won't be reordering them. 13 left currently.
personally i am not comfortable running a boost circuit off of an ICR cell. i will run them in my 18650 egos ... they actually work better than IMRs in there, but the PWM is tuned to ICR batteries. my VV and VW devices (and the wife's bolt) get IMRs.
How often do you guys change your coil heads? I wash mine up about once a week to keep the gunk out of the string but that only works for about a month or a little more.
One month isn't bad when compared to the price of a pack of smokes. I was getting 1-2 weeks when I was cleaning/dry burning every 2-3 days. Now that I've scaled back the dry burning, I haven't blown one in over a month...this is for Vivi Novas BTW.
