Im looking to get into cloud chasing. I am running a itaste mvp 2 with the kanger protank 3 mini . I love this battery, not sure what rebuildable atty to buy for it, I'm looking for something to run 2 or so ohms. Any suggestions from the peeps who have used many attys. Im not looking to spend more than $30. 3 post or 4 (two pos/two neg) would be nice. Thank you in advance for the info.
