Battery Protection
The battery circuitry protects the battery pack from extreme
temperature, over-discharge, and over-charge. To protect the battery
from damage and prolong its life, the battery pack circuitry will turn
off the battery pack if it becomes overloaded or if the temperature
becomes too high during use. This may happen in extremely high
torque, binding, and stalling situations. This intelligent system will
shut down your battery pack if its operating temperature exceeds
176°F (80°C) and will begin normal operation when it returns to
32°F (0°C) - 122°F (50°C).
