Abstract: A power tool system including a battery pack and a power tool. The power tool includes a power tool housing, a drive unit located within the housing, and a power tool controller located within the housing. The power tool controller is configured to receive a signal from the battery pack (for example, a battery pack controller), the signal indicative of a temperature (for example, a temperature of the battery pack); determine whether the temperature is between a lower temperature threshold and an upper temperature threshold; and limit a power to a drive unit if the temperature is between the lower temperature threshold and the upper temperature threshold.

Abstract: A power tool may include a power tool housing. A power tool may include a drive unit located within the power tool housing. A power tool may include a power tool controller located within the power tool housing, the power tool controller configured to: receive a signal from battery pack, the signal indicative of a temperature of the battery pack, and do not limit a drive unit power if the temperature is less than a temperature threshold.

Abstract: Power tools, snow throwers, and heated grips for snow throwers are provided. An exemplary heated grip for a power tool having a handle configured to be engaged by an operator includes a first heating element configured to be disposed at least partially on a first side of the handle; and a second heating element configured to be disposed at least partially on a second side of the handle, wherein the first heating element is moveable relative to the second heating element.
