Correct me if i've got this by the wrong end, but the argument seemed to
be suggesting that the battery would be run outside cell data sheet limits
to get that final reserve, which I find difficult to believe.

Aviation kit is generally designed with parts having generous operating
margins to improve reliability and/or safety. The worst case operating
conditions are analysed and components sized accordingly. If a proposed
battery doesn't meet the load requirements, they just fit a bigger one.
It's that simple.

Other than the ntsb report, there seems to be very little added info at
present and the proposed box solution looks more and more surreal with
each week that goes by. Come clean Boeing, tell the truth and publish
everything. It's the only way to really restore confidence. Otherwise
there will always be doubt and the tech pundits will never let the story
die...
