I just bought an 18650 aw imr battery [2000mAh]. Took it home, charged it till green [about 2 hours], as soon as I loaded it into my maxi roughstack, the spring at the negative end got red-hot, atty didn't fire. What the ....ing ..... I am so upset. I have no other batteries as it's a new mod, and I ordered some but also bought one from a local store to be sure I'd have one. For now, i'm smoking cigarettes. Someone help me out here.
