Thanks Renee.....I will only use the T2 and Vivi tank on the VV then!! and yes...my twist is the 1000mah from you! 
Hi Blue,
The DC Carto's Tend to pull to hard on the Ego VV Circuit. The Twist have a different circuit becasue there is no LED on them.
The EGO VV has to also carry the LED Screen that lets you know your battery strength, that is why I do not recommend DC, it can kill the battery pretty fast. Also I would use them Sparingly on the Twist unless you have a 900 mAh or higher
Hope that helps.
Thanks,
Renee
