Thanks. I know I need to get a voltmeter but I thought this would be a little piece of mind between checking the battery after a few flights.

Have you verified if the LEDs are calibrated correctly? By that I mean if they are fairly accurate. I will try this over the weekend by having the battery fully charged then go fly for 3 o4 4 flights, and see if the LEDs change. Then I will put it on the bench and "fly" for several more 10-15 minute flights to check the LEDs.

Thanks again.
