Hi Joe
I have a Rotax 914 not yet flying. I am going to raise the effective set-point on my Ducati regulator to make my Odyssey PC545 battery a little happier.
Add a diode:

Read the manual on Odyssey:

Click documentation, you will see that a little higher is desirable.

Even if it were to be somewhat discharged it would still fully charge at the 13.6 volt setting, it would just take longer to do so assuming the alternator has some headroom above the "normal" electrical loads of the aircraft.

Bob, Thanks for your words of wisdom.
To Ron P,
I could not find any reference to a diode on EuropaOwners.org. But I assume that the diode is inserted in the regulator sense wire. I had thought about doing that, but voltage measurements indicate that my battery is kept fully charged with the 13.6 volt regulator set-point.
The charging instructions in the Oddyssey manual
http://www.odysseybatteries.com/files/US-ODY-TM-001_0411_000.pdf
pertain to a discharged battery. Since my PC680 battery never gets discharged, the Continuous Float Charge voltage of 13.6 is adequate.
I appreciate your input.
Joe
