Does your ESC list lipo cutoff values as Low Intermediate and Hight? What does that mean?
Low, is a lower voltage, high is a higher voltage.
Low is 3.3 range.
Intermediate is 3.5 range.
High is 3.7 range.
It varies a bit depending on the plugs, battery packs and a few other basic things. It's very much why we went away from "Numbers" here, as they do not really "match" when the packs are checked. It's common to assume the voltage should match exactly, but that is not always the case.
