Switch to LIFePO4?
I have a trio of Rolls Surrette FS210 wet cell batteries that give me about 315 AH of usable capacity. My big concern is weight, the total is 400 lbs in my from compartment of the 5er, and I think tha...

AFAIK, PT has those two high amp switches for recharging one bank at a time. Normally, you would not have any disconnect switch between inverter and battery bank with those high amp fat wires. You might have a high amp fuse in a holder that would be easy to take out of its holder, not sure how those things work.
To isolate the Li bank from the I/C draw even on standby, you would have to shut off the I/C. I don't know, but assume there is an on/off button for that.
For the battery meter to show 80%, that would need it to be resting at some voltage where that is 80%. If the battery is under load and shows that voltage, it could be at a way higher SOC.
So to run the fridge and other loads off the battery to keep the battery under 80% but over 50%, how are you going to measure the SOC?
I think you have to get the battery down to 80% and isolate it from all loads. Now the meter on the battery is right, and you have to get your 12v somewhere else.
