Isub and ijust 2 tank so far, any subtank will work fine tho, should. Nice thing for me is when the battery gets kinda weak for the ijust 2 tank pop on the isub and it puts out just about the right amt of power for me and that tank.
One thing I've noticed with this battery is it is plenty powerful enough especially on a full charge, too much for the coils that I have. Definitely have to think of it like a mech mod cuz that's essentially what it is. Me personally I'm gonna play around with different "Atlantis" coils with that tank and see what works best for me.
