I wasn't sure from your post above, are you using the 3.1 ohm coils in it now? I generally use a 3.0 ohm, and it's fine with all 4 AA's. Warm vape, but not overly so, clouds of vapor everywhere. Congratulations on getting yours going. Welcome to the club
Nice work on the new one, much smaller, like the added batt meter. I have used an altoids tin as the enclosure for a puck mod and BH-341-2A-R: JAMECO RELIAPRO: Batteries. Fits almost like thats what its made for. Though if you used AAA holder I'll bet you could make a puck 2 in this way. Though I personally don't like the idea of usin smaller batteries to make room for a voltmeter, though I thought some might like the idea
i didnt realize about the voltmeter on the outside. just looked at the pics. and the altoids tin and link was justa different way i made youre old design, instead of the battery boxes.
