Yesterday I cleaned the innards of my copper tube using isopropyl alcohol. Put it back together and after about 5 or 6 whiffs I took out the battery before going to bed. It looked like this:
I have no photo of the inside of the tube but it had the same stain. I could remove it on both of them by wiping over it with my finger. I looked thoroughly for flaws on the battery wrap but couldn't find any.
The setup:
- Wotofo Phantom copper mod in hybrid mode
- Sony Konion VTC 5A battery fully charged, upside down (plus side to button with venting holes)
- 22mm Goon with .25 coil (dual 28GA SS 304 two stranded parallel wire)
What could have happened here?
