Most of the ESCs that have a "per-cell" cutoff setting "read" the voltage hooked up to it and calculate the number of cells that way. Of course, they probably assume a charged battery so if you hook a depleted 5s pack (~15v), it might think it's a 4s pack with at least 3.75v/cell. Of course, this would drain the battery down to 12v, which would be way too low for 5s. So, make sure you don't turn off/on the ESC towards the end of the charge or it might read it wrong.

IMO, lipos usually dump very noticeably so I think you'd see the loss of speed before you got to that point.
