I think we might be getting closer to the root cause of the battery problems. Anyone have any idea how solid state isolators and diodes (and lithium batteries!) react to conditions that burn out circuit boards? Even if described by Boeing as "a low energy arc that lasted milliseconds, very small", what happens to the bus voltage during the incident? How does the battery isolation/charging circuitry react? Has this been tested for on the bench?
