Hi all, I've been vaping for about a year but recently went to a DCT tank system with a 1.5ohm dual coil cartomizer on an Ego battery. I've been reading that 1.5 ohms on a typical 3.4-3.7 volt Ego will 1/2 the life of my battery! I've read that I should not be using a 1.5ohm dual coil cartos in my tank as Ego's can't handle it. (I have a 1000mah Ego-T battery.) It's my understanding that the Mah rating only tells how long my battery will last between chargings not an indicator of how strong it is. Ok...so here's my question: Should I be using the above mentioned system on an Ego? If not what about installing a 2.0 single coil carto into my tank. Really need some answers from some of the more experienced vapers here.
