Some Vari's report up to low 4.+ with Dual Coil LR's. I get up to 4.1v with no probs on a 1.8 i06, and i haven't pushed it higher.... no need.i usually stay a 3.7 with it for best flavor.
2.0 lets you go even higher.
I never got more than 3.9 with the LR 1.5 DC's myself, but not really necessary if that's your vape.
I mainly drip SR 901 attys 3.0 at 3.8 to 4.6v, but use others like i06, Iken 1.8's lately. I have 3 different tanks now that i have never set up yet lol... sold my iatty because the draw was airy and have a couple genesis rebuildables on the way.
I bought 50 dse SR 901 from Vaporkings because i have been going through one or two a week (on 2 PV's).
I hate carto's! But want to try them in tanks because they stay filled that way supposedly.
Iken Fusion carto's are said to be the best btw, by many, next to Boge.
Ukeman yea I am using a liquinator rite with the boge 3.0 been liking it at 5volts no problem. What voltage can I take the LRs too.
Which do you prefer cartos or attys?
Thanks
