The discussion centers on the comparative fire risks associated with battery home storage systems, particularly lithium-ion batteries, versus general house fires. Users comment on the current safety regulations in Germany, incidents in New York City involving lithium batteries, and the implications of battery chemistry on fire risks. The consensus appears that while the statistical likelihood of battery storage fires is lower compared to typical household fires, the potential severity of a battery fire can be considerably dangerous. There are calls for improved safety standards, especially for imported batteries, and a request for more information and studies on battery chemistry comparing safety risks. Users expressed a need for stricter regulations to ensure the safety of battery systems, especially as the popularity of electric vehicles and battery storage increases. Furthermore, concerns about hacking risks on internet-connected home storage systems were raised, emphasizing the importance of cybersecurity in addition to physical fire safety.
