I have the exact same problem as you. almost same batt. readings and tested them with a multimeter. You are right. There is nothing wrong with the batteries, but something with the mod or chip. I am very disapointed of the quality of this so far. I was working perfectly fine and now... DANG! I get this stupid issue. I am concerned that i might have spent over 300$CDN on this mod and two set of 3 quality married 18650 if there's no fix as this would make a darn expensive door stop... Wismec and Evolv you guys have to jump in on this. My device warranty just expired 3 days ago... Really! Ya!
