Buddy picked up a used mech mod for his first mod which I didnt recommend and was asking what he needed. I simply told him to go to a vape store and tell them you need some batteries that can sub ohm. He came back w/ 2 samsung icr18650 32a. Being as how I dont really keep up with the latest and greatest, figured they were just a new battery on the market. Since his batteries werent charged I gave him one of my charged vtc4's and said we can swap out next time I see you. When I was just looking at it I saw it wasnt a imr. Anybody try these? Couldnt really find any info on google.
