1. A battery pack configured to be interfaced with a power tool, the battery pack comprising:
- a housing;
a cell having a voltage, power being transferable between the cell and the power tool, the cell having a lithium-based battery chemistry;
a controller operable to control a function of the battery pack, the controller requiring a voltage at least one of equal to and greater than an operating voltage threshold to operate, the cell being operable to selectively supply voltage to the controller; and
a circuit operable to enable the controller to operate when the voltage supplied by the cell to the controller is below the operating voltage threshold of the controller.

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.
