So what will Electrovaya announce at battery day?  Choose one !

1.  The Solid State Cell is finished development and prototype cells are in prospective customers hands??

2.  They have manufactured an LFP cell and testing results are published?  If so then a customer should be announced.

3.  An energy storage customer has placed a large battery order for a large energy storage project.  Maybe a 15 MW/60 MWh distribution-level project?

All kinds of possibilities !
