Just got an Istick 30w, upgraded from the istick mini, and man is it awesome. I looked through some of the earlier posts and saw this has been an issue for others but when I use my Aspire nautilus and aspire k1 tanks with 1.8 ohm coils, the ohm reader displays as 2.0 ohm. They are both fairly new coils. Both only a day old. Is this a big issue or does it not really matter too much? Also along those same lines my nautilus 1.8 coils have a label on them that says 1.8ohm (3.3v to 5v). What will happen if I take the voltage up higher than 5v when using these coils. I do have a new nautilus BVC cotton coil that I haven't used yet and the label says that will go up to 8v. But this one is one of the older ceramic BVC coils. Thanks for any info.
