A Tesla battery has burst into flames during testing at the site of the Southern Hemisphere’s largest battery project.

A 13-tonne lithium battery caught fire at the future renewable energy plant, called the Victorian Big Battery, near Geelong Australia, and the blaze then spread to an adjacent battery bank, according to the ABC.

A toxic smoke warning has been issued in the area and fire crews will need to wait up to 24 hours for the blaze to die down.

The site is the second Tesla battery project in Australia after the 2017 installation in South Australia, a facility which Tesla head Elon Musk called the “world’s largest” at the time.

Representatives for Tesla did not immediately respond to CNET’s request for comment.
