Last night when I quit vaping I noticed a lot of black on the bottom(Flat Side) of my VTC4 I cleaned it off and most of it is now gone however it did have some discoloration. Today I am using it with a 4 wrap 22 gauge single coil in my omega and it seems to be working but I think there is some residue on the bottom of battery but I may just be paranoid. I also noticed the black on my firing pin. Could it have been arcing in my mod? And is it still safe to use???
Thanks in advance,
Mike
