I mean that sucker sounded like someone fired a gun in my house! Scared the hell out of me. Have no ides why this happened. I'll try to get some pictures. It was on fire and everything. Just a simple kgo battery on the charger. Thank goodness it was in my bedroom. I had thought about charging from my computer while checking out the ecf. Sure am glad I didn't. I don't think I'd have a face left if I had. Please be careful everyone! Dang it now I only have two batteries. Did I mention this scared the hell out of me?
