Eh, I found the problem. My 901 batts just aren't working for these cartos, even with the 901-808 adapter. I have 1 808 batt which is how I was able to test and find out. Thinking of selling my 901 starter, maybe with that I can save up some for an 808 starter. The 901 not only loses the TH, but also the flavor and it isn't too long after starting to use it that this happens. The 808 batt works fine, the TH of course dies down a bit from vaping too consistantly, but that comes back once I put it down for a little bit.
