This will not be a problem if you never fly long enought to drain the battery to a low level or use a type of ESC that sets the low voltage cutoff point via an initial setup program.
Just wanted to make you aware of this in case it applies to any of your projects.

I can see why that would happen. However, will setting the ESC to look for a set number of cells instead of auto detecting the number of cells, fix that? That way the ESC is looking for the correct voltage before initiating the start-up sequence instead of initiating the start-up when it sees any voltage that seems to be the correct for the ESC in autodetect.
