I have had some experience with this myself. I love the way people love to point out what they think is obvious. I lit up the inside of my explorer one day at the field. I for some reason set the charger to 4 don't know why. I knew what I did as soon as I heard the pop. I also blew up a a 123.2s when I forgot to change the setting back to 2s. Both of these incidents where completely my fault and I learned a great deal from them.
