Not sure I know the code for that last post.
My point on this thread definitely is that now that my house burned down, I AM paranoid. Even my Ryobi tool batteries are charging outside the house. I do trust them a lot more though, and charge them in a detached garage. If it burns I lose shit, but I can still live in the house. But hobby king packs will stay outside.
But paranoid as I am, I will run any shitty battery I want, since it aint never coming into the attached garage to charge! It don't matter if I run A 123 lifepo4, cheap ass 18650's or terrible dangerous lithium cobalt packs for drones. All same, not coming into the building I live in. So my paranoia is actually freedom.
Battery fires btw, rarely occur when just in storage. It's while they are charging, and particularly at top of charge that they blow. Or,, they blow when damaged, like crashes, dropping the pack, or the good ol KFF trick. The main thing about charging outside from now on, is I can nod off while it charges. The night my house burned, I forgot about the charging battery, and went to bed. I would be dead if my wife had not been awake when the house went up. She got me up fast, fast enough to call for help, and get the dogs out of the house.
The safest storage is obvious, more discharged rather than full.
What do you do if you can't store them outside? The oven in your kitchen is likely the safest place for them to be while you sleep. It will resist any possible fire long enough to buy you the time to get out alive, and wake up your neigbors if its apartments.
And of course, never fall asleep on any kind of charging battery. Not even the Roomba.
