The reaction uses the : VO+2 + 2H + e → VO + H2O (E° = +1.00 V) V + e → V (E° = −0.26 V) Other useful properties of vanadium flow batteries are their fast response to changing loads and their overload capacities. They can achieve a response time of under half a millisecond for a 100% load change, and allow overloads of as much as 400% for 1.
