Battery for a Kanger Aero Tank Mega

[Quadzilla]

Hey guys, I just purchased a Kanger Aero tank Mega since I want to upgrade from my started kit. My current battery that I had originally is and innokin Itaste. I would love to upgrade from this just not sure which path to take or which batteries I should look into. I would prefer one that not absurdly big. Something I can comfortably have in my pocket but also sturdy enough not to get messed up in there. Thanks for your time.

You could stick with iTaste by upgrading to an MVP 2.0.
