Here's the problem! I only have one 12 volt battery and it has to last 48hrs to run the control panels and alarms. Will I make it? What can I "do" to make this work? Thanks for the help!
Yes I think you will make it. Get a voltmeter and watch your voltage.
You should start fully charged at 12.7 and get down a bit as you go. 12.2 is getting low and below 11.9 is too low.
You could unplug tonight and see how it goes 24 hours but then get plugged back in so you will be fully charged for the off-grid adventure.
