Yeah I'm using a AW IMR 18650 that I bought from ProVape. It just did it again about 15 minutes ago. I think it's happened 4 times in the last 4 hours. I'm vaping at 5.3V and right now the battery is reading 3.5V with the battery check. It makes sense that the battery starts to work again after reconnecting it, but what doesn't make sense is how long it works. If it was almost dead then it shouldn't be lasting several more hours.
