This is actually very scary I know how important battery safety is. I came home last night and tossed a battery in, slid the door and walked thru the house vaping, but I felt really weak...fully charged 4.2v 30a orbotronic battery. I took the door off, and as they contact spark spark. It left this black spot on my batteries...I've over looked something I must have...any help would be appreciated or its gonna be shelved and collect dust
