Duel coil cartomizers and battery life

[Scoper50]

I have a quick technical question about duel coil cartomizers. Does anybody know if they are wired in series or in parallel? I started using duel coil carto tanks all day on my ego twist, and I expected to see my battery life shorten. This hasn't happened. In fact, I seem to be getting better battery life than I was using a single coil cartomizer. This seems backwards to me.

The dual coils run in parallel. It is an anomaly that you are getting more life from your battery. Were you using really low resistance single coil cartos, and switched to a slightly higher resistance dual coil?

My 100th post - yeay!

Spaceballsrules are right, a 1.5ohm dual coil, is essentially two 3ohm coils in parallel. I buy 1.5ohm dual coils, and clip the top electrical wire loop, to make it a single coil 3ohm carto! It works great! BTW I find, since the 2 coils are mounted vertically above each other, you may occasionally get a burnt tast, or even worse, burn the filler around the top coil, if it runs a little low on juice.

There should be zero difference to battery life, running a single coil 1.5ohm vs a dual coil 1.5ohm - it is still just 1.5ohm !

well at the same power. I run dual coil 2.5 ohms on my provari @ 6 volts. Yea, 14 watts. I use singles at around 8 watts...
