So I have just noticed that my luc blu6 is showing my batts at full charge but noticed my RX was not showing a full charge, so not really paying attention I never really noticed this until a few days ago. So I take what says 4.2 full on my blu out and put it in my luc4 it shows 4 volts and charges until it says 4.2....2 of my buddies has the same charger and have verified the same thing. I can't find my voltmeter so I just have the 2 chargers to work with.... Anyone have the blu and another charger to verify if yours is doing the same thing? Disco.
