electricucian? I have seen bad things with wrenches dropped across batteries even 12 volt car batteries although in this case it was a large battery bank in a submarine but I was curious about the 48V sources in switch rooms.
Electrocution is but one way to die from too many columbs. Internal burning is a big one. Most people die, not from immediate cardiac arrest, but rather from kidney/spleen/liver failure as they try to remove the cooked you parts from your bloodstream, and clog up. (First responder treatment is multiple saline inputs to flush you out, and keep flushing you. This via a friend who was "lit" and lived.)
The only way I've seen anyone die from being shocked is heart failure. This was a very very large AC hit though not DC.
The instantaneous short circuit current available from a CO-grade battery string is nothing short of frightening. It will easily turn a 18" crescent wrench bright orange and start spitting the molten metal around within few seconds.
I'm surprised you're still around after a sub battery accident. They're a grade up from most CO's in available current, I'd bet.
Yes, they are I don't recall the amps off hand but it was amazing. It does take a lot of juice though to spin motors that large and run all that equipment considering your primary power source is nuclear also. In my case I wasn't the one who was hit I was a fair distance off and someone working, an electrician, touched a wrench across the terminals on one cell only. For get a few seconds pretty instantly the wrench was gone as well as a better part of his hand and wrist. However, touching both terminals on the cell did not yield a shock which was what made me think and ask the question i the first place. I can't imagine the damage possible though if someone in that setting touched one of the main bus's.
