I tested Milwaukee M18 power tool batteries to see what low voltage cutoff and protection they have. Some of the batteries discharge below the recommended 2.5V per cell discharge limit. I think this is being done to allow the batteries to be pushed harder, but it is poorly implemented and could be damaging the batteries.
