I’ve noticed the spring in the CV gets very warm on me, +arcing @ .2 ohm, maybe not so noticeable at higher ohms, but is definitely a waste of power producing heat. I love the CV, but mine is benched until I get around to making a spring out of silver/copper. The one that comes in it and in the rebuild kit is magnetic, telling me it’s brass plated steel, very poor conductor.Do not understand why..
But it appears that the same battery used in my Coppervape lasts longer per charge in my new Pico Squeeze...
That is based on ml vaped per charge using the same battery and Wasp nano atty that was used in the Coppervape....
