And why not just introduce a DC inverter with a breaker into the system within the same box as a double-check? Also, attach a thermometer to the outside of the box so you know what you're dealing with. But that's the engineer speaking - "if it's worth doing, it's worth overdoing."
You can have the best Lithium cells, the best battery management systems and you still have a very very low residual risk of your battery catching fire.
I’ve watched a few videos that demonstrate these bags, and they give you about a minute to drag it out of your home at best. There are flammables cabinets made to contain the energy, or you can fashion your own or use a charcoal grille.
