On my 8-bar LEAF which isn't far away from 7-bars, you can see that the voltage spread starts going up significantly by the time you get down to 40% SOC. By LBW (34% SOC), there is a clear separation of voltages with cell-pairs 1-48 starting to drop below cell-pairs 49-96.
But it is far from 5 remaining bars, which is where I was. Now, I didn't try to do the readings at any specific (high or low) SOC, but it is true that probably my readings were close to 100% SOC. I will have to try to go back through the records and see if there were any taken at low SOC when there were 5 or 6 bars.
And I too saw that LBW was there at about 34% SOC, I'm thinking that would have been huge to be going another three or four miles before the LBW and down to 20% SOC or so. I still in general was able to avoid even LBW (34% SOC) at 5 remaining bars. I guess it depends on Nissan's definition of "low," but with a third remaining I don't consider that "low."
