Watch it its well worth it , if my old T Series motor let go , I'd do this to it rather then 50k on a new engine .
The answer to the question: "what could possibly go wrong?" https://reneweconomy.com.au/tesla-megapack-container-on-fire-at-site-of-australias-biggest-battery/
What a revelation! Of course no ICE car, power station, fuel depot or coalhandling facility has ever had a fire....oh, wait...

I think the main players just gave Tesla too much of a head start. That gave time for Tesla to get world wide acceptance and time to make a great product at a great price. 5 years ago, if a Tesla and VW were available for the same price, almost no one would buy the Tesla. Now that is certainly not the case.
Food for thought. For all electrical things. 1 earths magnetic field is reducing rapidly and accelerating in its reduction. In some areas down over 15 % plus https://www.esa.int/Applications/Observing_the_Earth/Swarm/Swarm_probes_weakening_of_Earth_s_magnetic_field 2 this then leads the earth to be more prone to a Carrington type event https://www.nasaspaceflight.com/2020/08/carrington-event-warning/ Yes the probability is low but the damaged caused during the Carrington event was when the Earths magnetic field was near full strength for this to happen now, a Faraday cage is useless.
