So, when the car dies due to 12V battery no longer supplying the power for the computers, due to parasitic drains, is the jump starter package (like the various ones talked about here) really just providing enough power to get the 12V battery (and therefore the computers) up to a usable voltage, with the hybrid battery pack then doing the main job of starting the car and charging the 12V battery?
Said another way, "A jump start battery for a '24 Nautilus could be trivial size from a CCA perspective, as the 12V battery doesn't do any classic, short duration but high amps, engine starting - it just needs to supply enough power to the 12V battery/computers so there's a usable "12V" voltage, relatively small current, so that the computers can then have the hybrid battery pack supply power to one of the eCVT motors to actually start the ICE. Once everything is up, engine running, the hybrid battery pack then takes care of charging the 12V battery via the BMS."
