> Japanese inspectors have cleared the maker of the battery, GS Yuasa, of any defects before the unit leaves the factory. But both Japanese and US investigators continue to examine and test the batteries to understand why they failed after they were integrated into the 787 electrical system and operated on commercial flights. So it's not the batteries but how they are integrated into the plane? How is this any different than how Tesla has packed their cells? Their cells looked pretty densely packed from my POV.
