100 car batteries wired in parallel!
styropyro

Styropyro wires 100 car batteries in parallel to produce more current than a lightning bolt and tests what happens when it is shorted. The experiments, done with other YouTubers, show spectacular effects of extreme current.
Cited in battery and electrical safety threads as a vivid demonstration of what very high-current battery banks can do.
