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...

I started a thread that has a link to a quite conservative LI fact/suggestion sheet. They recommend, that for best battery life, 0.2 C is the maximum load (and charge rate).
0.2 x 600 amps = 120 amps. That's not going to run the microwave (or the roof air, either).
If you believe that a 600ah lfp bank can't run microwave or a/c for an extended period of time or other high draw and still get long life from them that's delusional.
From your link in other thread...
"LFP batteries can also last a very long time. Our Battle Born LFP batteries are rated at 3000 cycles, at a full 100% charge/discharge cycle. If you did that every day it makes for over 8 years of cycling! They last even longer when used in less-than-100% cycles, in fact for simplicity you can use a linear relationship: 50% discharge cycles means twice the cycles, 33% discharge cycles and you can reasonably expect three times the cycles."
They were talking about BB batteries and BB claims up to 1C charge/ discharge for 100ah battery.
