Ok, so I am using a Pro Tank 2 with a 1.8Ohm Coils. My Battery is the 1100 Mah battery, not a VV a steady 3.7. However I am burning coils left and right with the pro tank 2. I am not sure as to why but It seems as soon as I put a new coil in in about 4 puffs my coils has burned. I have no clue what is going on.
