Charging Profile for 2019 Cornerstone
I know someone has posted this but I can’t find it. My settings are set to custom and I don’t remember doing that. This is my current settings. Could someone tell me the correct settings?
Thanks

Thanks, that looks like I am set right but my house batteries are staying around 12.8.

Your right, your batteries should be up to float voltage settings, 13.8.
Try pulling the shore cord and running something on the inverter for a few minutes and see if the voltages come up.

I have a 2018 Cornerstone which has a different VegaTouch user interface, but looking at the photo you posted I believe your problem is that “Absorb Hours” is set way too low. It appears yours is set to one-tenth of an hour when it should be set to 2.5 hours for your 800 Amp Hour house battery bank. See attached chart.
With your coach being a 2019, I believe you have Relion house batteries. If so, they recommend 14.4 to 14.7 volts for absorption charging and 13.6 to 13.8 volts for float charging. As such, your settings for “Absorb Volts” and “Float Volts” are in range.

Absorb hours at .1 doesn't look right for any kind of battery.

It may look better now but its in absorb mode.
It still needs to drop to float at 13.8 volts when absorb time is done.

It doesn’t appear to be doing that. Anyone have any ideas?

I will give that a shot. Will update later after it falls below 13.5.
Thanks

Also if you have not already try a reset of the Vegatouch system.

Try unplugging the battery temp sensor ( BTS ) from the inverter/charger. Small phone jack on it.
Sometimes they fail and the charger thinks the batteries are very hot, and drop the float voltages.
Unplugged, it defaults to 77° and if it was bad, it will normalize float charging.
