So my friend needed a pv to use for the day so I gave him my cheap mod and it shorted out internally. He comes up to me and asks me why it's not hitting and the first thing I think of is short so I tested his atty and it was good, so I figured it must be the mod and sure enough that's what it was. This isn't like a k100 where there are no wires and when you get a short, you get a DEAD short, this one has small wires so the battery wasn't burning hot or anything, it was just warm. There was smoke coming out of the mod when I pressed the button, maybe it was the solder joints in the mod, with no atty connected and when I removed it I noticed the battery had white residue stuck on the top. I don't feel comfortable using this particular battery in a mod so I'm wondering if it should be thrown out or can it be used in a protected APV like mini provari?
