Factoid, lithium 5th most abundant element in earth's crust. Vanadium... Way scarcer.
Finding it, ...lithium, in any commercial quantity is the trick.
Opionoid, vanadium far better suited to large fixed installations and too heavy for vehicle installs. So I think both have a future for complimentary applications.
Having said that. I've got a free lead acid battery from work that I charge with a discarded 250w solar panel via a 20 buck regulator.... Runs all my outside lights charges powerbanks etc.... So price plays a part, V gets to dear.... Redox Batts take a delay. Not a problem for Tmt as we not selling batteries.... Keep it pure play Ian.
