So I decided to go for a mod and ditch the my unreliable VV batteries. I just picked up the Joytech E vic. I took the plastic wrapper off the battery and tried to turn it on and no luck, I can't get it to turn on. I don't know which way the battery goes in if the the negative or positive side touches the spring and if I need the plastic disc in to make it work. I can't find anything online to do the first setup.
