The South Australia government announced that Tesla had "fully installed" the world's largest Li-ion battery, which CEO Elon Musk had promised to deliver within 100 days or free. The new battery helps stabilize the state grid by storing power from a nearby windfarm after 1.7 million people were regularly subjected to power outages.
