Batteries are akin to gas tanks. The gasoline that goes into them is akin to electrical energy that goes into them
So I think it's more akin to $ per litre to build a gas tank of X number of liters in size. The cost to build electrical energy storage devices (i.e. batteries) is dropping year over year.
