when saying ZCell can be marketed as a premium product I didn't mean to say Redflow should price it higher (my view is that they have the cheapest battery on the market going by warranted kWh), rather I don't see a need for them to offer a smaller/cheaper/stripped down version of their battery with reduced warranty just to reach entry-level price points.
I'm comfortable for lithium batteries to dominate the sub-10kwh storage market as I don't really see the point of getting batteries that cheap if inverter+installation then makes up a large part of the cost and within a few years of capacity fade you have very little to show for your $
