Interesting competition. So they can extend life and maintain charge better than lead acid but : a) still need to be recharged b) need to have swap out/storage space if you run 24 hour operations
would love to know the costs compared to lead acid and Gendrive.
Also isn't there some safety issues with Lithium Ion battery's - is that harder to address than Hydrogen I wonder?
May be worth adding to a basket of stocks that are in this space though.
