Hi I just received a brand new P+ 18650 and I'm having issues getting it to work. I tried the panasonic CGR18650CH and my atomizer never fired. I tried about 3 of them. It did work with a EH 2000mah IMR, however the atomizer was weak. I put the same batteries in my ssggts and they worked fine. What could be the issue? I'm definite that there was contact between the atomizer and the center pin. Any help would be appreciated thanks!
