Where components are made does not really matter (to me).
That several distributed suppliers must be integrated does not help. However, this is just "normal".
The components in the Thales-assembled Battery do not perform as a safe, integrated, rechargeable source of stored electricity.
Concur, at the system level.
IMHO, individual cell charge/discharge is inadequately controlled/monitored.

The fact that a marginally -safe technology is used, certainly doesn't help!
Right, but are ladders more than marginally -safe?, after all, one can fall down
What matters is management. That known deficiencies (10 bat's out of 30 replaced at ANA ) were not addressed in time is "not uncommon" mismanagement. Would they have been proactive, they could have started what the NTSB does now after the first three failures, and the fleet would not have been grounded.
That's what I am here for, to learn.
