After a weeked of successful use (just got it), one of the batteries started acting strange in the charger. After more than an hour, the main LED was flashing red, and the firs of the three "Cells Equaliser" LEDs was flashing. Typically, the first three were on solid along with the main one, until the green started working its way in. Any ideas? I'm calling the dealer as soon as they open, but just wondering if anyone else has seen this. Also, when I hooked it to the copter, I got a loud repeating beep that sounded like an alarm.
