Flow batteries have some fantastic properties. Their energy output and capacity can be scaled independently. They are safer and can be made from material that are easier to source.

They are also have high upfront costs and poor energy density, so there have not been much application outside of grid-scale deployments. Getting something practical for onsite commercial, residential, and vehicular applications have been something aggressively pursued. (Solid-state batteries being another battery tech that is also pursued).

So for someone to make a open-source DIY flow battery that can scale well can change a lot of things.
