'24+ Nautilus Hybrid Charging Voltage

[markfm]

Curious - Do others see the hybrid "12V" voltage consistently up in the 15.2V zone when it's running?

(Vehicle was started around 10:02).

Yes. At that voltage the battery should be charged so no real current going ino battery. Charging charts like novo say 14.8 is max voltage for agm.

Got it, found this in the WSM (414-05, subsection DCDC Operation):

"The DCDC steps the high-voltage down to a low-voltage (between 12.0 and 15.5 volts, depending on vehicle needs), providing power to the vehicle low-voltage battery systems. Depending on the vehicle and environmental conditions, the DCDC is capable of outputting up to 260 amps to the 12-volt battery."
