whereas aviation batteries are built and tested to a very
demanding spec and will be used well within ratings.
Should be. In theory yes. In daily use you know what may happen.
A battery today is a complex device. No longer cells inside a case. Even software algorithms could be responsible for the problems.
In
787 Batteries and Chargers thread there is a graph on that (optimization).
I would have thought that they would have gone the extra mile with this, but they must have had their reasons...
It seems an absurd what we are learning on that.
