Hmm... Getting ready to restock and bump up to the tanks. I normally use a mix of the Coolcarts and Wowcarts with the King Diamond XL manuals and the pass-thru. I tend to vape all day, mostly at my computer and if I've read things right, I should be able to use either the 1.5ohm DC carts or the 2 or 3ohm single-coils successfully with both my existing batteries and pass-thru and the ego batts, is that correct? The V4L rep I spoke with a while back said that the single-coil would likely last significantly longer. I'm sure I missed it in my search earlier, but I didn't see any posts about the compatibility of the manual pass-thru and the tanks.
Thanks ahead of time for helping clarify the issues before I place my next order.
