Sorry... I was mostly teasing you.. and I fully understand your reply.. and don't expect you to protect idiots who play with batteries from themselves. And in this field I am surely a rookie and sometimes an idiot.
I spent several weeks reading and learning about LiFeP04 Batteries and installed a class T fuse in my RV battery bank, and 8 280Ah Batteries under my steps to replace inadequate 12 wet cells that factory installs. I have watched Andy put the current meter between a full cell and an empty cell and then slowly short them together and demo > 100A flowing from the full battery to the empty battery.. That's kind of scary, and a wake up call to your constant reminding of "don't drop a wrench" on your terminals you won't like the result.
The entire top of the RV battery install is fully covered with a large slab of 1/4 thick G10-FR4 (circuit board insulating material). The 200A BMS is mounted with plastic screws to the G10-FR4 slab and so my exposed terminals are minimized and protected.
With that as background your comments that batteries as you demo in the video, represent a very simple DIY, and are on a metal rack, surrounded by non-flammable materials, and correctly wired, and protected with a Class T fuse.
You also make the point the these batteries (correctly installed and utilized) are about as dangerous as a stack of wood.
I fully agree.. thank you for making that statement. I also agree that my wood stove in the corner of my basement is likely a higher risk to burn my house down, if I forget to clean the chimney, or use a shop vac to suck up burning embers.
Burning embers sucked into shop vac result in a shop vac fire. (Don't ask me how I know).
My option is to place a similar rack in my concrete basement, next to a concrete wall well below my main circuit panel. I could easily place a Wyze observation camera over the unit, and a smoke alarm, and have remote notification if the alarm goes off. (Wyze hears the alarm and notifies me)
This option gets me 30Kw of backup power, is ugly, hidden, but very useful inexpensive and functional.
And as you stated, I doubt you spent more than 8 hours building that bank.
I am not an "influencer" and don't really care what is popular, just a little concerned about doing things safely, and you have addressed that concern.
Thanks for the reply, and sharing.. and sorry if I hurt your feelings.. but I don't think I did.
I appreciate your sharing on your battery and solar adventures.

PS.. I have captured a screen shot of your reply for my lawyers when my house burns down.
