Thanks for all the input. Today I tried a smoktek 3 ohm carto in a Smoove tank on the EgoC Twist and at max 4.8 Volts and got zilch - no vapor, no taste. Then I switch to a 1.5 Ohm Smoktek carto at 3.8 volts and wow, what a difference. Great vapor, taste, and a warm hit.I'm not sure if I should even try to push this to a higher voltage. If I do and something fails, will it be the carto or my twist?
Flyer, I've had my Twist for about a week now and have done some reading on ECF about them. On another thread that I can't find right now, someone said they think the Twist has a maximum amp output of about 2.5. A SR atomizer (about 2.2 ohms) at 4.8 V will draw about 2.2 amps, so if the 2.5 A limit is correct, there is a bit to spare here. Running a LR atomizer (about 1.8 ohms) will draw about 2.5 amps at 4.5 V, but there are 0.2 V increments and some LR atomizers are a little lower than 1.8 ohms, so realistically, 4.2 V is probably a safe bet as a maximum with LR.
I have used a LR atomizer, metered at 1.7 ohms and I did crank up the voltage to max on the Twist. Nothing bad happened to the battery, so it must be smart enough to limit its output. I did not use the LR atty again after trying it that once, but it's nice to know that if I ever make a mistake and connect a LR atty, it will not hurt me.
