Is There a Difference Between Lithium-Ion and Flow Batteries?

Lithium-ion batteries love to be at float. That's sort of 50%. But that's really good for grid stability. If you're half full, you can absorb a bit,. top up, take power off the grid to help balance. You can also push some back on. And it wants to bring to nothing. Whereas, lithium-ion, you have to protect it and all that stuff. Very interesting.
