I have a power station but its internal battery is a 48 V, so when I run 12 V things you lose some efficiency stepping it down to 12 V. I also have a 12 V battery and I'll just often run those device devices directly from the battery and I get much more run time per ah of battery.
Community Reviews
This 12V 280Ah LiFePO4 battery is being used as affordable house, RV, boat, camper, and off-grid storage, with Bluetooth monitoring and enough capacity for serious loads. It is praised for running 12V devices directly, pairing well with solar, and scaling into 24V or 48V banks for larger systems. Real-world reports include trolling motors, backup power, and even air conditioning, though runtime drops fast on heavy AC loads. It is not a starter battery, and charging or wiring often needs the right lithium charger, fuses, and connectors.

It is technically possible to fry your alternator if you use too high of an amperage for charging too, but I dont think there's any chargers that allow that high of amperage, so no worries there unless you create your own charger and have some really heavy gauge wires that could handle the amps so the alternator would fry before the wires burn up
Does anyone know how to disassemble so I can do top-balancing myself? It looks like it is maybe glued shut?
Definitely do separate rather than all-in-one type of things. It's usually cheaper, and if 1 part goes out then you can easily replace just the one thing instead of everything. I have a noco charger which is fine, but I bought it when there wasn't cheap availability of other brands like there is nowadays. I'd just get a cheap eco-worthy (or similar) 10-20A charger for charging from shore power. The DC-DC usually takes care of everything unless you're staying put for 3-5+ days. Mine lasts me almost a week with the same things you listed minus a microwave, but does include an instant pot used once a day and a drip coffee pot also used once a day

Assuming it's a backup pump, the LFP benefit of more cycles isn't a huge benefit, it's more about calendar lifespan. Also, LFP don't like to stay charged at 100%, like you would want for the case for a backup sump.
How much storing at 100% degrades the battery capacity is still up for debate. It likely changes over the life time of the battery. There is one research paper about it but it's pretty technical and not conclusive. OTOH, the manufacturer recommend battery is what 75-100ah? Even if the capacity of this one degraded significantly, it still might provide more capacity, assuming it could still deliver the proper voltage to power the pump.
TLDR; LFP may or may not be better for a backup sump. Nobody knows.
I went with a deep cycle battery because it's a known and extremely important that mine works but may try an LFP next time.
