In the vanadium redox flow battery; the maximum safe operating voltage for a single cell is about 1.8 V at full changing condition. Under discharge, the cell can operate, at practical current densities, from a voltage of about 1.5 V down to a level of 0.6 V or even deeper, although the discharge would typically be restricted to about 0.8 V.
