Default Charging Over Voltage D-180

Original battery from 2012 (700TT) was getting weak so I bought new Odyssey PC-680 and installed yesterday. Flew 2.5 today and had overvoltage warning. I have dual screen D180 and John Deere VR AM101406 which I installed about five years ago. When I got the warning, I switched EFIS to EMS and saw voltage at 15.0 - 15.1 in cruise flight. Amps varying +1 to +2. I’ve never had over voltage warning prior to today.

My friend has Legacy RV-12 w/ Dynon HDX and he sees 13.9/14.0 volts in cruise flight.

So, the usual questions….

• Is 15.0/15.1 volts too high for charging Odyssey PC-680?
• Where can I find Van’s list of settings for Red, Yellow, Green arcs for Legacy RV-12 w/ Dynon D180? I don’t want Dynon data file, just want to verify settings are correct.
I just found 12 D180 PRESETS
• Anybody else having this problem?

Thanks in advance...
