12 volt wanted when lithium battery switched off

Can I get 12 volts via my multiplus compact when my battery is switched off but am still connected to shore power. This is so I can use the 12 volts on my RV without having to have the heating on to keep the battery warm, TIA

@Big Ste

Is your multi in pass through when your battery is off? Meaning 220V is available?

You can use a blue smart IP65 charger as a power supply, not sure how many amps your system uses but they can supply up to 25A depending on what model your purchase.

No, if I disconnect my battery from the Multiplus, it does not deliver 12v, as a power supply would do.

If you find a solution to this without buying extra devices, let me know :) I would like it as well.

Thanks everyone, guessing it’s just not possible.
