They usuall burst with fire. You'd have to have hardshell battery with no venting, and likely no protection circuit, and a way to cause sustained load on the battery, without the user noticing the heat first. Eh.
A short on a battery with protection circuit installed basically does absolutely nothing to the battery.
I'm yet to see a video with fire and a lot of smoke at minimum.
As much as I'd love to believe this couldn't happen without physical tampering, I see no good reason to.
