LFP cycle life is given as up to 7000. That's almost 20 years at one cycle per day, but a 16h (was it 18h?) battery isn't going to be doing 1 cycle per day, so I don't think 25 years based on cycle life is that unreasonable. You also get background "calendar" aging, but here in the UK that isn't going to be super fast due to the cooler climate, and the long duration means the c-rate is low so they won't be heating much that way. Overall I think it's reasonable if a little optimistic.
