Hello all, I was hoping someone could help understand whats wrong with my EGO 18650 PV. It is brand new, and when I opened it straight out of the box, screwed in a brand new 1.8 LR atty and starting vaping it seemed fine. Shortly after it seemed very weak, so I decided to charge it. It didnt take long to satisfy the battery, which definitely made me worry. Then I put the atty back on and the light just flashed, and wouldnt fire. I then tried a different atty, standard ohms this time, and it worked. I then tried the 1.8 LR atty on my Ego twist, and it worked great too. Now the 18650 will not fire at all with any atty, carto, etc. When I push the button with nothing attached, it works fine, but as soon as I put any load on it, I get the fail flash. I tested the battery, and it is full at 4.2V, so I know that isnt the problem. The attys I am using are fine, so it must be the control unit. Anyone else experience this? It is the old school model, non variable. Thanks for any advice you may have.
