Note : Lately Reneweconomy seem to be on auto pilot regarding their fact checking and proof reading. Redflow do not make a vanadium battery.

This ability to supplement EMC current offering of Lithium battery with VRB is in my opinion a game changer.
EMC now have multiple generation tech. Multiple storage tech, and collaboration with leading industry players. Working with SEI on sales and installs ..brilliant
Imo.
