Lawnmowers are provided. A lawnmower includes a first battery having a first voltage, the first battery mounted on the lawnmower; a second battery having a second voltage different than the first voltage, the second battery mounted on the lawnmower; and a booster configured to boost the second voltage to the first voltage, wherein the booster is connected to a common rail operating at the first voltage.

Lawnmowers

A lawnmower comprising: a body; a cutting element coupled with the body; a motor configured to drive the cutting element; a sensor comprising an accelerometer configured to detect an angular displacement of the lawnmower with respect to a vertical axis and a wobble of the cutting element with respect to a horizontal plane; and a processor configured to: compare the detected angular displacement against a tilt threshold value; compare the detected wobble against a wobble threshold value; and control an operational speed of the cutting element when the angular displacement exceeds the tilt threshold value or when the wobble exceeds the wobble threshold value.

Lawnmowers with safety features and methods associated therewith

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.
