I fully agree it's undersized. They should bump up the size or even better have a 2nd smaller 12v that acts as backup.Modern ICEV, with 15 - 20 computer modules, use a large wet cell/AGM 12V battery on the order of 60 to 90 amp-hour. My experience with my cars has been such batteries easily provide a service life between 5 to 9 years. My BMWs mount the battery in trunk to keep it away from underhood temperature extremes (and for chassis weight balance), which helps with longevity.
I see LVB battery issues several EV have as a case of using an undersized battery for the 12V electrical system. What I've read is most EV use a 35 amp-hour battery. A moden EV has no less a current draw than a modern ICEV. It's understood ICEV need a battery with a large current capacity to start an engine on a sub zero winter day, but also the batteries are powerful to support keeping modules energized during sleep mode.
It seems like a design flaw IMO.
