You don't want to fully drain the main battery as it would do severe damage to it and most of the 12v system has a phantom draw of power so to keep the main battery from running out they have a separate one

Compared to what the main batt can provide, there's barely any draw from the other electronics.

That's not the point the fact is that there is some dumbass that probably will let it sit at 0% and kill the battery

Battery management electronics don't let you drain lithium batteries to 0%. It's a severe design flaw if it does.

You still end up with the same problem of no power for locks when it turns off the battery
