This is weird but I used to try to find clearomizers that would fit my batteries now I am looking for a battery that will not only fit with but also look well with my protank. That is the only tank I will ever use anymore. Right now I have an ego-T and a Vision Spinner, I have no problems with my batteries and really love the spinner. I would like to get a "bigger battery" one that looks well with the protank. Any suggestions?
