It sounds like this is being used for day/night storage here as opposed to spot demand, so it may be using more of the charge range.

I wonder if these batteries have reduced peak power output, can they fulfil the kind of balancing that you are suggesting? I guess if they had enough it would be fine.

I just assume so because of their application in EVs but might also depend what kv level lines they're stepped up for.
