Breakers were design to be installed by the average Joe, as are drier legs. The failure mechanism of an improperly installed breaker is that it doesn't work properly, or it gracefully melts in a metal box which is required by law/code to handle that exact case of graceful melting and small plastic fires. The tools and technique required for dealing with stack of little fire bombs, that explode if poked, bent, or overheated, sometimes at a much later date, while sitting in your garage/living room, has a much more serious failure mechanism. And, more than that, most DIY battery packs I've seen involve lack of funds and Aliexpress cells. In the RC hobby community, everyone knows that you store DIY battery packs, especially those made with cheap Aliexpress cells, somewhere where they're free to spontaneously combust without consequence. Battery packs are scary. People who understand that have better outcomes [1] than people who don't [2] (tbf, these are Lipo) [1] https://www.reddit.com/r/fpv/comments/fb1u4d/thanks_reddit_you_all_saved_my_house_from_burning/ https://www.reddit.com/r/fpv/comments/fb1u4d/thanks_reddit_y...
