The Z3 just passed inspection today following an extended upgrade of the battery pack. It has 1½ Leaf batteries now, for a total of 72 cells and ~290V. It has a new BMS, too; the Orion is much better than its predecessor. I'll be integrating that with an Arduino to send the info to an iPad or iPhone and drive the original fuel gauge in the dashboard.
It's time to pop the top and enjoy the beautiful weather!
