I have been watching Eestor for over a year. Of all the positive and negative comments I have read in the past the only thing I would like to say is technology like this doesn't happen overnight but when it does watch out. I am sure the original price I've heard for an Eestor in a 25 KWhr size is probable low but even twice the original price puts it's cost per KWhr is way lower than any of the Long life batteries. They first published a cost of $3,100 for a 54 KWhr pack when mass produced. That was probably way overly optimistic but solid state mass production does have some history of really getting cost down.
This is more positive news. All us EV fans can do is hope and wait.
