Based on another member's recommendation, I'm reposting my question from the general forum to this group (didn't know it existed). I'm getting wattage too high errors when operating over 14.6 watts (well within the 20 watt max.). I'm using a kayfun built at 1.3 ohms with a 35 amp Efest 18650 battery. I've tried multiple batteries, checked my atty, and have an 87 IQ. I do not use the "boost" function. Any ideas what may be the source of this problem?
