  1. 7:30 Note that "100%" and "0%" are just political decisions when it comes to battery cell chemistry. The actual chemistry works in voltage but difference manufacturers set "100%" to somewhere between 4.10 and 4.35 volts. The cell lifespan degrades the higher you charge the cells and the cells of manufacturer which sets "100%" to 4.10 volts doesn't seem to degrade at all compared to the manufacturers that set "100%" to 4.35. When it comes to smartphones, Samsung was known for setting "100%" to 4.35 V. This resulted in great battery performance in short tests with new handsets but the battery degraded really fast if you charged the phone to 100% daily.

  2. 4:30 I guess the unit should be "Wh/kg" instead of "watts/kg". And the same for imperial units, too.
