The answer comes down to cost. LiFePO4 batteries have enough capacity that they can be held at 80% and still beat SLA on capacity. The problem is that LFP wins on gravimetric and volumetric energy density; two metrics that aren’t particularly important in the context of a UPS. It’s a large brick that sits on the floor.
