All consumer battery packs will have a BMS that has a cutoff somewhere above 2.5v. Due to the non-linear discharge curves you get very little energy going from 3.0v -> 2.5v, most BMSs will have a cutoff somewhere between 2.8v and 3v. This of course varies between chemistry types.

Consequences. Capacity is irreversibly lost due to otherwise cyclable lithium being trapped within the SEI. 33 In addition, the SEI layer is less permeable to Li + ions than the electrolyte, restricts electrolyte flow through pore blocking and consumes the electrolyte solvent. All of these effects increase the overall impedance of cells, leading to power fade.
