I know that somebody MUST have a device that will plug into a leaf pack
and display/use the BMS in the pack.
Anyone know where to find such a unit?

Hi John, 

You can connect to the Leaf BMS with the Leaf Spy Pro app. For use outside of a Nissan Leaf, the Leaf pack needs to be supplied with 12v and you'll need to buy or make your own Leaf battery LV connector to OBD-II port.

 For iPhone, this LELink BLE OBD-II adapter works well. For Android, I can't remember if the LELink works, but the OBDLink MX+ is the best one you can get. Hopefully, Leaf Spy will get an update for iPhone to use the MX+ as well; it updates much faster.
