That 18650 Calculator

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. LiPo cells come in a HV variant that goes up to 4.35 max.
