Okay so I've been using the 6ml tank with the single coil replacement because the dual coil will not work with my v2 battery. I've seen that this has been killing my battery quickly cause it was not meant for it, so I bought a new battery so I could use the dual coil cart. Today I just got my vGo battery at 1000mAh. I tried the dual coil with it and it won't even produce any vapor. The dual coil is at 1.5 resistance and the single coil is at 2.0 resistance. The single coil is working fine with my vGo but I would definitely like the dual coil to work. Do I need a higher resistance like 2.0oHm or higher for it to work? Any help would be nice, thanks.
