well I thank you for the suggestions. unfortunately that was not the problem. the charger is not working. on a 2 cell battery it is showing up like it has 3 cells in the cell status screen and number 1 cell shows no voltage. we had a lipo checker and verified all the batteries we were testing were good. also tried different balance boards. Even put them on another battery charger and they would charge. I'm very upset because this is the second quad charge I bought that had issues with.(I had to send my hitec back because it was getting hot and the fan would not turn on.) very frustrating.
