It might be different for 30 kWh as it's been asserted the discharge curve is different on that battery vs. 24 kWh packs. I'd imagine a '16 or '17 service manual should specify.
This is strange to me because at that low an SOC, the voltage delta is always large. I have seen 200 mV+ differences FREQUENTLY in my pack which by all accounts has always performed well over 3 LEAFs. Keith posted a screenshot of his LEAF Spy at low SOC and the voltages are as expected, all over the place.
As far as driving it; the bad cell will degrade MUCH faster than the rest of the pack and eventually you will start to see shocking GOM readings that go from 65 miles to turtle in a few miles so tread lightly but guessing you have some time before it becomes critical.
Others have posted bad cells here as well but guessing their cells were bad a while before they noticed anything amiss.
