Thanks for your concern, but seriously, contained to the ceramic crock any heat or flame is only going straight up towards a 12 ft sheet-rock ceiling. I charge MUCH bigger Lithium batteries in my garage almost daily. I own several Lithium powered tools including a really big EGO brand battery mower that routinely gets charged without any such containment. Even my cell phone on my nightstand or one of 3 laptops charging at night poses a statistical bigger threat. Our lives and homes are full of lithium batteries now days and how many home fires are you hearing about from charging them? Laptops, cell phones, rechargeable robotic floor vacuums, drills, saws, edgers, mowers, wireless security cameras, portable boom boxes, portable work lights and camping lights, lots of kids toys, those are just some I could think of quickly in my own home that all use the same battery chemistry. I just threw this out there for those that might be concerned.i can see what you are trying to do there ,but really leaving batteries on charge when you go out, is not a good idea inside your home ,if one of those batteries were to catch fire it would not take long for all of them to be alight ,please stop doing it my fellow flyer ,dont be the one person who's house burns down because of a battery fire
not everyone lives in a dwelling with a 12ft high sheet- rock ceiling and regardless of all the things you mention ,it is still not a good idea to leave batteries charging unattended, of course if you are happy to do it that is your choiceThanks for your concern, but seriously, contained to the ceramic crock any heat or flame is only going straight up towards a 12 ft sheet-rock ceiling.

“ Here's what I do if they need charging but I have to leave. A crockpot liner is perfect”It's rare, but Lithium batteries can get real dangerous while charging. Here's what I do if they need charging but I have to leave. A crockpot liner is perfect
During a thermal failure, it is not uncommon for the off gassing from the battery to propel it across a room (spreading fire as it travels). Most bags or containers purpose built for LI chemistry recharging are built to contain the device from all directions, yours is a great start but does not account for the device leaving the liner. I am a fire investigator and unplug EVERYTHING when I leave the house, not worth the risk. Unattended charging is a bad habit and will come back to bite you.
