I Drive Startup Problem.
Regarding low battery, stop/start should stop interfering quite prematurely (at the battery charge level detected about 75% I recall, unless it's Brake Energy Regeneration threshold in fact
, it can be found on the Internet: mind the official naming of "Auto Start Stop") and there's quite a list of other reasons for that (my "favourite" is the engine isn't at operating temperature - "drive moderately"). AFAIK (reportedly), if the battery level is detected dangerously low a verbal warning should pop up besides cutting things off to save the power.
