what batteries do you use?

Yeah, if they could get 1500 out of a 123, then a 18650 5 volt and maybe like 4500mah would be killer, now that would do it.

I hear the 900 mah rcr123 tenergy (blue) bateries will not work with the DBSB. Their circuit protection trips. They work GREAT with the normal SB top however. If you are using a DBSB, Id use a 3.7 v battery, or the 750mah (yellow) tenergy batteries. For the regular SB top, I'd use the tenergy 900mah batteries for 6v. They fit better, and last longer then the lifepo4 ones, and have a protection circuit built in.

I beleive the atties in the DB top are wired in parallel (cddz, correction?), if that is the case then: with a 3.7 volt battery and two 801 atties you would have a 9.13 watt output. Right in the sweet spot. That same setup with 6 volts would yield 24 watts, much higher than the commonly sought after 8-10 watt range. Im no math wiz, so I could have messed something up there, but my vaping experience agrees with this.
I have tried the blue 900mah tenergys with my DB top and, as leathermonkey said, I can only get 2 or 3 vapes before it stops working. I don't have the yellow 750mah tenergys to try but I dont think 6v is necessary on the DB for the reasons stated above.

Thanks for the answers guys, cause i have the blue tenergys and needed to know if they would work or not... Is there a big decrease in the warmth of the vapor using the DBSB with the high drain compaired to the single SB at 6v? I know vapor production will be HUGE, but I like the warmth of the vapor too...
