Pit Viper. Call horizon on that battery. I bet they make it right. After this accident remember if you have a question about your battery don't try and fly it a second time. Voltage check does not tell you if your battery is charged to the ma rating of the bat. Also if the bat was way down a 45 min slow charge would have been about 7min. Do a fast charge and cycle the battery. I always cycle my new bats before I use them. Dennis
