Just bought a little boy rda using on an mech mod no kick or anything. Building with 24g kenthal wire with cotton for wick. Also using a 35A high drain battery. When I use one coil it works great the full coil heats up/glows evenly (7wraps). When I go to do the same exact coil to Do duel they heat up but not enough to glow or make any real vapor. Now I have made duel coils that work fine but with 28g kenthal. Is this problem because of to many wraps (7) with the 24g kenthal?
