Fires in electrical switchboards and transformers are relatively common and can be very severe. There is a huge amount of electrical current flowing in and out of these megapacks. All it would take would be an incorrect termination, a faulty relay or switch installation to cause a short circuit and resulting arc fire. So it doesn't have to be the megapack itself that starts the fire, although that is definitely a possibility. Any fault in manufacture or the installation of a big battery is likely to show up during initial testing. I'd be more concerned if this occurred after commissioning when the installation was fully operational.
By the way how much does Wall Street value the energy business anyway? I thought it was close to zero.
