Lithium batteries typically last four hours.

What does this even mean? What a useless metric. They last alot longer than that for me. How much current does their battery draw when lasting 100 hours? What are the costs compared to lithium? Zero useful info other than "company spends money"...

Utility-scale lithium batteries currently deployed have almost all been designed so that they kick out some number of watts for four hours. (How many depends on the facility)
