Abstract

A method and system for battery protection. In some aspects, a battery pack configured to be interfaced with a power tool includes a housing, a cell, a controller, and a circuit. The circuit is operable to enable the controller to operate when the voltage supplied by the cell to the controller is below an operating voltage threshold off the controller.
