I don't just read here, I read all over the place. And I think that's the key. When other people and sites validate what someone is saying, that gives them credibility.
Sunking's basic beef with LiFePO4 batteries in a PV environment seems to come down to the line of -- they haven't been documentedly around in PV environments long enough to be able to reliably conclude that they have the long calendar and cycle life that some people have experienced. That doesn't mean that they can't, or don't, but just that there isn't the widespread data to validate that to be the case.
If you look at all the posts that he has made they all tell a consistent story. The information in his posts is backed up by posts from Steve G and Barba on this forum who have batteries over six year old, my batteries which are over three years old and a number of others on the Energy Matters forum who have batteries between 3-4 years old. Compare this to Sunking's raves that Chinese LFP batteries are all a pile of crap and will only last two and a half to five years. If I were in court and had to pick who is the credible (truthful) and reliable(provides correct information) witness I would have to choose Dax over Sunking.
Another factor that maybe more apparent in Australia is that there are now a number of large multinational companies selling LFP and other lithium ion batteries in the retail market for use in PV environments. These companies are offering offering ten year warranties on their products.
