Musk's allegation is that the 787 battery is a poor design, not that it was manufactured incorrectly. Your point would be a good point if Musk's allegation were that GS Yusa had manufactured the batteries incorrectly or if the satellite battery were of the same design as the 787 battery AND used under similar conditions. However, my understanding is that the 787 battery is a new design and used under conditions rather different from a satellite.
