Anyone have a suggestion? I've seen conflicting information on the best ohm cartomizers and atomizers for a 5 volt device. One vendor advertises a Boge 3.2 ohm 510 cartomizer but states that it is not to be used on a HV device. I have recently read that higher ohm carts and attys are what should be used with 5 volts. It was recently suggested that a problem I was having with my 5 volt box mod (with 14500 batteries) cutting out was due to the low ohm (1.5) of the cart I was using (and a reg 2.5 510 didn't do much better.) So ---higher ohm?
