My first flight on my new quad and I accidentally disarmed about 5 feet up over gravel. Everything seemed OK but the battery had a few minor scratches in the plastic and the outer most clear layer was cracked. I was coming in to land anyway so I just put the battery away. When I put it in my charger at home the charger reported an error. I checked the cells and the 3rd cell reports the same voltage as the second and the total pack voltage reads at ~11V. So using a multimeter on DC voltage, I put the ground on the first pin and they read: ~3, ~7, ~7, ~11 which does not seem right. I also did a continuity test and both of the pins 2 & 3 on the balance connector report being connected. What is going on? The only thing I could think happened is the cells got bridged internally and, luckily without exploding, balanced each other out.
Is that possible? I looked real close at the balance connector and the pins don't look bridged there. I don't know how to take it apart safely to be 100% sure. Right now the battery is in my bat safe, but is my best option to discharge and toss it?
