Abstract

A system and method for battery protection. In some aspects, a power tool battery pack operable to supply power to a power tool includes a controller. The controller is operable to sample a battery pack condition in at least a first sampling mode and a second sampling mode to produce a plurality of measurements. The controller is further operable to average the plurality of measurements to produce an averaged measurement, and operable to modify operation of the battery pack when the averaged measurement is outside a specified range.
