I guarantee that the 787 problem is not with the battery technology but with the assumption that it is possible to charge as many as 8 cells in series without problems. The weakest cell WILL reverse polarity and appear as a short after the fact. This is true for any battery technology. I have done it with diehard lead acid batteries. To be safe each cell must be charged individually. Otherwise it is similar to pushing a chain. Unless each link is PERFECTLY aligned there will not be success. Unless each cell is PERFECTLY matched there will not be success. Since this is clearly impossible in this universe there will be future problems unless my warning is heeded. Time will prove me correct, Of that I am certain. Watch and see!
I do not doubt that this is true, but can anyone explain why we have not heard of such problems with lead acid or NiCad systems? There are scads of 24 volt systems of all battery types in aircraft, marine, and ground transportation equipment, all of them having 12 cells in series.
