Ok, first off I am a certified bone head for this...there, I said it. I was doing a little flying around my yard to discharge the batteries to 50% for storing them. I remove the battery and let it cool in ambient temps. So for my last flight, with the others already cooled down, I was "hurrying" the last battery's cool down with a little help from the freezer. Was going to only be a for few minutes, what could it hurt, right? Well today when I opened my Phantom case, I said "Hey, where's my 4th battery"? You guessed it, 24 hrs at sub freezing. What would you do with it? I haven't even put it in the bird yet. Anyone done something like this? Advice please...
