Efusion duo running 18650.....went to change batteries the other day and I put the fresh ones in and now my mod will not turn on. I was about to trash my mod then I plugged it into Escribe. To my surprise it turned on and it recognizes the batteries. When I un plug it from the computer it does not come on. Stealth mode is not on and batteries are 100%. I’m left scratching my head. Can anyone help me . Luckily I have a backup mod or I would have been sol.
