Claim 0:
1. A power tool system comprising:
a battery pack including:
a battery pack housing,
one or more battery cells located within the battery pack housing,
a sensor configured to sense a temperature within the battery pack housing, and
a battery pack controller located within the battery pack housing, the battery pack controller configured to receive a first signal from the sensor, the first signal indicative of the temperature; and

a power tool configured to electrically and communicatively couple to the battery pack, the power tool including:
a power tool housing,
a drive unit located within the housing, and
a power tool controller located within the housing, the power tool controller configured to:
receive a second signal from the battery pack controller, the second signal indicative of the temperature,
determine whether the temperature is between a lower temperature threshold and an upper temperature threshold, and
limit a drive unit power if the temperature is between the lower temperature threshold and the upper temperature threshold;

wherein the power tool controller is further configured to not limit the drive unit power if the temperature is less than the lower temperature threshold.
