Strange, I've been using mine religiously for 3 weeks now and no sign of any problems... K.O.W.! I have 2 pairs of batteries and drain them till the mod warns of low battery (about 3.2v). The difference in voltages of cells at discharge is from 0.02 - 0.03v. From what I've read, acceptable. No heat, connection, or performance issues at all. I got it from VapeNW.
I mostly use temp mode @ 0.15 - 0.25 ohms with a max of 50W. On occasion, I crank up a kanthal build @ 0.2 ohms with a max of 60W, and yet to have any problems. Maybe it's at higher power levels where things get wonky... I.D.K. Hope mine holds up, and everyone gets squared. It's such a comfy mod! Hope it lasts!
