Nick, why are you waiting to charge? Still flying at 9.4v? Yeow, scares me.
The battery is 9.6v at nominal voltage. Waiting to charge it until 9.4v simply assures that it is sufficiently discharged. The low batt alarm on the 12X does not sound until 9.0v so I still have a safety margin. I don't always fly down to 9.4v but I do sometimes.
Not having to deal with proper discharge concerns would certainly be an advantage with a Li pack.
