Hello, recently got a Vapor Titan soft touch manual. I use a tank with it. My question is that when after vaping, after taking the tank off the battery, is it normal to see just a little bit of moisture on the top of the battery? It is usually just a little ring of foggy moisture. I always wipe it off and am constantly checking to see if it is there or not? Is this normal? And will it damage my battery if i don't constantly wipe it off?
