Sounds like the batteries that come with the unit cannot handle the current drain from 1.5 ohm dual coil cartomizers, and are giving you all they can, but can't meet the current demand. AW IMR batts have a very high discharge rate, and can happily give all that you ask of them in this situation.
Just as a safety measure, I wouldn't use the batts that came with the unit for the DC carto's, Mindfield. If you are asking for more current than they can give, they are being stressed. This could be an unsafe situation, especially in a mod with stacked batteries.
This is one of the many reasons why AW IMR batteries are so highly recommended.
