Help! Ran both batteries down!

This seems to vary wildly from brand to brand. (I saw a Danish EV car reviewer in some sort of Chinese car, that ran out when it had an indicated SoT of 4% and he was 1 mile from the charger....Car went from "This is fine" to "Yeah i dont want to drive any further" in literal seconds)

To be honest i would worry, running the ZS EV below 10%, unless i knew i was pretty close to home or a charger, but in my Tesla i have more than a few times arrived home with 1-2% charge and offcourse plugged it in as soon as i parked.

One time my wife was with me on a work trip, she drove me to the worksite and was then to go charge at a SuC (Before continuing on to do something of her own), the Tesla said it would arrive with 1% (Was already low, but she was not that far from the charger).

Drove there, but offcourse instead of going across the motorway, she turned ON TO the motorway. (Guess who was the only thing or person NOT responsible for that :) )

She called me and asked what to do, i told her to do the 5 miles to the next exit, turn around and go back and just go to the charger.

So she was at 1% and had to do 10 miles and a bit to get to the charger...

She arrived with the SoT indicator stating -1% but got there without it even limiting her (She did elect to pop behind a lorry and do only 55 mph) and charged up.
 
When battery is out of balance, the weakest cell dictates when car switches off irrespective of the SoC

My home LFP was out of balance in initial days and at about 15%. It would shutdown as lowest cell was triggering cut-off
