Oh, absolutely, in the aggregate there is no contest here. I just wanted to illustrate how incredibly fast lithium fires can spread.

I've made a bit of a study of this because I use Lithium Ion batteries in volume. I take a lot of safety precautions because I realize full well how dangerous they are. At the same time I have a 25L canister of diesel and another with gasoline sitting around and I have zero expectation of either of those spontaneously combusting.
