Information only Lithium Polymer Batteries can be extremely dangerous under the wrong conditions, eg. short circuit, charging a damaged battery. ⚡

Lithium from my school days is a very light (floats on water)(while reacting with it), extremely reactive metal, it reacts with common substances, such as Air, water, and in pure form has to be stored in oil, if you held it in your hand it will react with you, most likely burning through your hand. Nasty stuff. Treat it with respect

Note if a Lithium Polymer Battery catches fire do not put water on it as it will react with it, making the problem worse.

When charging put in a fireproof charging bag on a non combustible surface such as a cement floor, just in case, better safe than sorry.
