  The revolutionary battery tech which they so generously "open sourced" the patents for.

    18650 is just the cell though. What Tesla brought to the table was their battery babysitting tech. Let’s not pretend Tesla hasn’t given us some excellent engineering.

      Can you link me to those patents then, because I didn't see them at the time. all I read was that they tested 4 types of batteries, and picked the best one, then wired them up. You had to buy the other equipment seperately to plug them in to your home solar. There was nothing of value in the patents at the time they released the Powerwall.

  18650 is not a battery tech in itself, it's mainly just a form factor.
