Hi,
mm43 @ # 635
patented charging algorithms
it seems, cell voltage history (JAL and ANA) were lost
PCB´s certainly are FUBAR and only option is what NTSB is doing now. By lack of other options (the "smoking guns" were certainly partially destroyed)
IMO Boeing obviously could innovate but:
1) The batteries replacement (VERY LOW MTTR) should prompt engineering attention.
2) Tracking on batteries performance (low performance) should started months ago. (could be just software inside charger)
Boeing high rocks were indeed concerned with what engineers said?
