Excellent post !
My post was basically;
Lions are safe.
BMS can be cheap if well done.
And Your post is that a human BMS usually works fine - which is of
course true with a small nr of modules.
Lion batteries do not magically start fires ...
neither do D cells.
Likewise, lion batteries == 4 volts at the cells.
Flooding all the cells in salt water wont do anything, except degrade
the terminals.
At 4V, nothing harmful should happen.
The only harmful/risky part is at the series-voltage, above about 40-50-80V.
You could probably dunk a tesla-battery system in salt water for 2 days.
wash it with shampoo, flush the coolant lines, replace the
electronics/pumps, and run another 5 years.
As such, afaik, the cells themselves wont know or care about being in
seawater.
After 100+ PCs were flooded, afair, we washed them and installed them,
and they ran fine.
Most failed due to corrosion, within a year, we did not wash them well
enough.
A PC ran in an aquarium, at cebit, where I was, about 1998.
