I am looking for a straight answer. I have a Gold rush mod @ 3.7v, i just ordered a tank Replacement Dual Coil Cartomizers, 1.25 ohms and Dual Coil 510 Chrome tank Cartomizer, 3.5ml. Will this 1.25 ohm carto work good at 3.7v?? What ohm works with just 3.7v? 2.0ohm single coil? And what ohm Dual coil carto? Thanks i am just getting confused and hope i ordered the correct ohm DCC! ?
