Got to the hangar and made a short flight yesterday.
Voltage readings (engine off):
Battery (Aerovoltz lithium iron) with Master Off: 13.25v
Battery with Master On: 13.11v
Panel 12v outlet: 12.97v
Panel voltmeter: about 13.8v (a little parallax error in photo below)
Went flying, and with just the strobes and landing light on, saw the voltage gradually go from about 13.7v to 14v where it seemed to level off:
This is I think about .3v higher than the Ducati. Note the panel mounted voltmeter is consistently showing about 1v high.
I was a little surprised at the high resting voltage - I'm used to seeing about 12.7v on most lead-acid batteries. But the Aerovoltz data sheet says that higher voltage is typical, and the 14v charging rate is in the acceptable range:
Anyway, so far, so good. If anything changes, I'll report back.
