The previous thread was closed, so I won’t be surprised . [ed. Text bashing my management style and how I run this site removed. Please read the posting rules. dr] The reality is that until fairly recently no one knew that an overload situation could cause the battery to irrupt into smoke. This seems like a catastrophic failure that is extremely dangerous. Yet no one knew this would happen. Now we have a measure in place to prevent it. Until fairly recently no one knew the BMS could catastrophically fail, slagging the battery. What if this happened in flight, wouldn’t that be a catastrophic failure?
Isn’t one of the purposes of this forum to discuss potential problems and failure points in our airplanes? I realize that the chemistry is different in this battery versus the 787 batteries, so the same type of failure is not going to occur. However the facts are indisputable that these batteries have had two significant failure modes that were not identified prior to the company getting an FAA certification. Ironically that FAA argument put forth in the previous thread is completely invalid. The 787 batteries were certified. FAA certification does not prove that these batteries are safe. It merely proves that we haven’t identified the failure modes yet. All systems have a failure mode. The real question is how severe and how frequently will they occur.

To recap:
1. [ed. Text bashing my management style and how I run this site removed. Please read the posting rules. dr]
2. If you disagree due to the PROVEN FACT that these batteries have failed in potentially catastrophic ways, despite being FAA certified, please just be quiet and don’t ask questions.
3. FAA certification automatically imparts safety, despite the failure of FAA certified batteries previously - just don’t look at the man behind the curtain.
Seriously though - given the short time these have been in mainstream installations, isn’t a certain level of questioning a good thing?
When my plane flies it may very well be with an Earth X but I want to be well informed about the concerns and “it’s FAA certified” should not put anyone’s mind at ease.
