    To be fair I think it is there as a backup for low temperature climates, the Lithium batteries wont charge at temps that low, but they still could have setup the lithium batteries as an emergency backup for all the 12v stuff.

      When the car isn’t driving I believe the main battery isn’t connected for safety reasons. It’s a high voltage battery, and having it connected all the time even when the car is being serviced is an unnecessary safety risk.

      Yeah they could and probably should use a different battery technology than lead acid. Preferably something with a wide temperature range. Lithium Titanate Oxide anyone?
