LiFePO4 generally has a 0.5 or 1C discharge. You'd end up with a 500W UPS that could run for 10 hours, or 48v+ battery packs.

and yes, they're also happy to heave to: plenty of DC ups' use NMC. Apc can't even be bothered to make a consumer class UPS that works with PFC- at all.

Depends on the type of LiFePo4 cells, ones designed for higher power can easily do 5-10C or more. But that's not needed for a UPS. Most common high energy cells can handle 3C.

3C or 20 minutes of runtime would be in the realm of most UPS ratings (remember the LiFePo4 cells have a lot more energy/runtime in the same space).
