They have a YouTube channel with some case studies and discussions[1] the channel intro shows high level what the battery chemistry and mechanism is - pumping electrolyte past a membrane and either dissolving or precipitating Zinc + Bromine to charge/discharge. They seem to be making a 10kWh cell which they can stack into a shipping container sized larger cell, and then deploy those to make grid-scale storage, rather than home use. Presumably they have an answer for if all the pumps in all those containers need regular maintenance, but I haven't thought about that until now. ('liquid tracks' should have been 'liquid tanks' in my earlier comment).
