Just received my torpedo kit today and I am really excited to get back into vaping with this mod after a year hiatus. Because this is my first mod though, I do have a couple of quick questions about the 18650 batteries. Do they come precharged or do they requiring a preliminary charging?  And, how will I know when the batteries are fully charged? Finally, are there any precautions I should take when handling these? Like, is it acceptable to leave them on the charger overnight?
Thanks so much!
