I was gonna say too, you'd get much better vapor production and battery longevity if you raised the volts. Or you can make a 1.5-1.9 ohm coil and get great vapor, but the battery wouldn't last as long compared to a 3ohm coil with high volts (like 4.8ish volts, don't quote me on that), but you have a MOD which should last you at 3.7 volts with a 1.8 ohm coil which is still about the same vapor production as 4.8 volts with a 3ohm coil.

^I'm still sort of a noob with the whole electronics 101 part of vaping, but I'm 99% sure that that's correct. Safe Vaping Power | Voltage | Resistance | Ohm Chart
"the chart" ^ doesn't list 3.7V with a 3ohm coil to be in the yellow zone of "power level may be too low to produce a strong vapor", but it's borderline, you want it somewhere in the middle of the green blocks (Amps are written inside the blocks)

Just started rebuilding Vivi Nova coils myself, and yeah, it's great fun and I'm amazed that my fat fingers actually managed to build 4 heads on the first day, without making a single short or anything :D
Using Kanthal D 0.20 (AWG 32), but will probably get some 0.15 in the future, as I can't coil it up close enough to get more than about 2.2-2.4 Ohms, they're still pretty good though :)
Using 4x1mm silica for wick btw.

I wouldn't know, as I just started out rebuilding them yesterday :)
But a "factory head" would usually last me a good 3 weeks or more, vaping about 2-3 ml per day.
I don't know if it's just me being hyped about being able to rebuild or not, but I think I like the taste better with the rebuilt head, compared to a fresh factory-made one.
