Damn Rum!
(Wait a minute.. I freaking LOVE rum!)
I'm glad that Loghomeguy chimed in... obviously with low resistances like these, netting-out the parasitic resistance of the test tool is important.... and I "rummed" right through mentioning that!
Be sure to mark that atty with a big red-X (imprinted with a hammer) and don't use it anymore.... a trail of failed batteries will be in its wake.
Sailor Jerry for the win
The atty in question is now historical, marked and relegated to the "rip it apart for jollies" bin.
What concerns me is that it seemed to be working just fine. I had zero indication that things were strange, from a vape point of view. Flavor, vapor, battery life, all were normal. Then suddenly battery life went to zero. What stops LR atty #2 from deciding "Ah, hell, I think I'll eat some batteries this morning"? What kind of sign might I be looking for to prevent this from happening again? (besides forgoing LR atties, 'cause a standard res atty on 3.1V sucks)
