Not always a petrol station within (reasonable) walking distance John. Ring RAC or AA for help...……….

Well yes, but do they carry spare electricity too?

The conventional 12V battery is fed by the main battery pack though

I managed to flatten the battery in our Astra because I forgot to disconnect the dashcam (for some reason the 12V accessory port in the Astra stays powered even when the ignition is off).

I guess there must be a connection somewhere. I know on the only occasion I ran out of power, the emergency lights were very bright. Thus the lead acid is fairly well charged at the point of the main batteries going phut………….

It would make sense to have one battery charger charging the main battery (which is high voltage), which in turn charges the low voltage lead acid battery.

There is probably a legal requirement that the lights (and hazard warning lights) must continue to work if or after the main battery system fails, so again it would make sense that the LA battery is maintained by the larger main battery whilst the car is being driven. Without this arrangement the lights would go out long before the car ran out of motive power.
