Hi, I have a Vaporshark DNA200. Last year after a long delivery, battery was not charging i have done USB Recovery Charging and it fixed. I didn't use the device last 2 months. Now I tried to charge but it doesn't charging. I have done several times "Perform USB Recovery Charging" but it doesn't work. Cell Volts: C1 1.77 C2 1.46 C3 1.60 Any idea? Thank you.
