Well, I have fallen in love with Provari's and recently grabbed a V1 in the classies just to have it. I am currently running two V2.5's with Protanks at 1.8Ω coils at 3.4-3.6 V. I am running my drippers at 1.4-1.7Ω coils at 3.6-3.9V respectively. Will I run into problems with a V1 in these ranges? As I understand it the V1 offered 12.5 watts and max amp of 2.5 ? By the looks of it I should be good to go with a V1 , but have read that some folks ran into E2 codes while running lower Ω coils. Just how widespread were these issues? Thanks in advance for any replies.
