I'm liking clearomizers a lot lately, I have an after market one that I like very much I'm using with my V2 batts, it has a screw on mouthpiece and a slightly larger capacity tank at 1.3 ml. I have seen it stated that the best ohm resistance for V2 batts might be around 2.0 to around 2.2, these are 2.5's, and seem to work great for me. All this falls outside my area of knowledge, I'm wondering if I'm using battery faster with the 2.5, or am causing any harm instead of going with a 2.2 that is offered for this particular clearo, or even a 1.8? What are the pros and cons of what ohm I can run on V2 batteries? What am I gaining or losing at any of these ohm values? Also, anyone know what ohm's the LMax run at? Any advice would be greatly appreciated as I go through the learning curve on my vaping tools.
