How much do those batteries cost and can they supply power for multiple days or a season if your renewable sources aren't providing like normal?
Not to mention the environmental damage from producing and disposing of batteries.
I agree, there are better options for mass scale long term energy storage than batteries, e.g. (green) hydrogen, methane
