So I have 2 evod batteries and 2 iclear 16 tanks for different flavors. The problem I'm having is when I try to use one of them it will flash 3 times and won't let me smoke but the other one works fine. I'm assuming that something is wrong with the tank because I switched the tanks to the other batteries and the same tank had the problem even though it was on a different battery. Does anyone know what this is and how to fix it?
