Hi. I just came in from flying the MPP using my four batteries. I let the batteries sit on my desk for a day to cool etc Just before hooking them up to the charger the next day i pressed the power button on all four to see if they we all reading the same one light reading as I fly them until they have 15% charge before changing them out. All the batteries indicated one green light after pressing power button except this one battery that blinked 3 times instead of just showing the single green indicator light. Does anyone know what this 3 blink indicator means?
