Which battery are you going with? I still have not decided which one (or 2) I'm getting.
Are you doing a monitor with a shunt?

I suspected that the wire "from the alternator" ran through the battery isolation switch. Seems logical...
I'm leaning heavily towards the following...as described on Amazon...
"
12V 100AH Self-Heating LiFePO4 Lithium Battery with Touchable Smart Display & APP Monitoring, Built-in 100A BMS,1280W Load Power, 5000+ Cycles , Perfect for RV/Camper, Solar, Home Energy Storage". I like the automatic self-heating feature that will be activated by the BMS when the battery is connected to a charger at -4°F to 4°F. It also has a Bluetooth feature for displaying battery information on your phone. It's currently (pun intended) priced at $320.00 on Amazon.
I like the heat feature...as I gaze at the thermometer and it's 31 degrees here in Gig Harbor. I like the blue tooth monitoring feature because I don't have a clue as to how to hook up a shunt and I'm trying to keep this as simple as possible. And of course, if for some reason this turns out to be a disaster, I can throw the whole mess in the garbage and start from scratch without having spent too much money.
I'm also debating the merits of adding another solar panel, but I want to get the battery project done before I tackle that idea. I had a couple of solar panels on my trawler for many years and they sure helped when we were anchored in a little bay somewhere over a period of days...
Thank-you for your reply. I appreciate your contribution to this project and if you have any better ideas, please feel free to offer them up.
Cheers!
