Using water on an electric fire sounds like a dumb idea to me. But yeah, the MSDS does seem to say that...

A venting lithium ion battery isn't usually an electrical fire.

Overcharging a battery isn't the only way to cause it to vent :)

Obviously there should be a physically separate circuit for cutting off power in the event of catastrophe. That's pretty much rule-of-thumb for large li-ion battery banks.
