LiPo batteries are what are used in electric model aircraft. I have a couple of small quads that I mess about with. When I got into the larger models I purchased a LiPo for it and the appropriate charger. The safety warnings that accompanied it about how to charge, when to charge, where to charge, what to have on hand when charging, all because of their tendency to got POOF! Use a programable balanced charger, place the battery in a fire proof envelope, inside a metal box, outside and maintain visual contact with it at all times, how you do that when it is inside of two containers I don't know. If it starts to swell, if it starts to get hot, if it starts to emit vapors, unplug it from the charger, let it cool, do not continue charging, dispose of it properly in accordance with local laws and regulations. Which no one seems to know what they are. If it catches fire, if it explodes, do not pour water on it, rather smother it with sand or use a non-water fire extinguisher.
Then GM issues notices not to charge your Chevrolet Bolt inside your garage or near your house because of a potential fire risk when charging. Then GM issues another safety notice not to park your Chevrolet Bolt near other vehicles in park lots because of a potential fire risks that may damage other vehicles that may occur if the battery gets to hot.
Put me right off messing about with anything with a LiPo battery in it.
