Intentionally vague use of “emergency situation” to encourage people to share. If you handle emergency situations as a profession, what’s a particularly interesting one.

    I was camping at an event. I had recently finished recharging a large lipo battery (3S 9000mah). The battery went from normal to nuclear in a second or 2.

    Thankfully I had it clear of flammables and in a lipo bag. Even so, it started 3 grass fires in the time it took to get it out of the marquee and wet enough to extinguish it. The event volunteers were there within 40 seconds, with fire extinguishers. Thankfully we already had it under control by then.

    Lesson learnt, always use a fire resistant container to charge in e.g. an ammo can or a cooking pot. Also assume it can turn into a fireball with absolutely no warning, and plan accordingly.

      Metal bucket or similar, half full of sand, is your best safety solution

        A bucket of sand is fine for a static location, but not very portable.

        A perfect solution that is unused is a lot worse than a mediocre one that is easy to implement.

        If you’re going that route, you want 2 buckets, 1 1/4 full. You dump the failing battery into the 1/4 full one, then dump the other over the top. That covers you till it gets outside into open space to burn out.

      Yes! Lipos are so fucking dangerous. Had 3 transform into fireballs on me, in different occasions. Now they stay in ammo boxes.
