Default Carado Banff AGM Battery Voltage Question

Iím a new RV owner, new to the group and need HELP with a AGM battery voltage question.

BACKGROUND: I have a 2018 Hymer Carado Banff RAM ProMaster 2500 (gas 3.6L engine) that has an AGM battery listed as 105 AH @ 20hrs. The other day I missed shutting off the Frig and now notice the monitor voltage display at 12.4 volts with the Battery Disconnect switch enabled but when the Inverter switch is also enabled the display then reads to 13.4 volts. Iím concerned since YouTube RV AGM battery videos note that an AGM battery reading at 12.4 volts is about 75% charged.

Which RV monitor display of AGM voltage is the one of concern to know about the battery charge percentage . . . Only with the Battery Disconnect switch enabled or with both the Battery Disconnect switch and Inverter switch enabled? As usual the Carado Owners Manual is useless about explaining this detail concern.

Now recharging the battery by home hookup and can speed up charging by starting engine using the generator unit (GU) for an hour or so (about 2,500-3,000 watts watts/hr charge). Naturally would have been smarter to keep a better eye on the voltage, install a Low Voltage Cutout Unit or have more than one AGM battery connected in parallel, or pair of lithium iron phosphate batteries.

I have a number of other questions for another time about adding another AGM battery in parallel or replacing with a pair of lithium Iron Phosphate batteries, access to current AGM battery and whether any Inverter/Charger unit parameters might be required. Hopefully there are some RV motor home battery experts out there.

Default You will find more on this Facebook group

There is a Facebook group called Carado and Sunlight owners with 600 members. There is a mixture of vans with ecotreks and agm batteries. Our Banff has ecotreks so I can't help more with your questions.

Is the rig plugged into shore power when you see 13.4V?

Does your RV have solar panels?
