A cell module assembly includes multiple lithium-ion battery cells connected in parallel and an electronic controller. The electronic controller is programmed to receive useful life data for a useful life indicator of the battery cells, save the life data to memory to create a life data history, determine a life measurement based on the life data history, compare the life measurement to a first end of life threshold, determine if the life measurement has met the first end of life threshold, provide a first end of life output indicating that the life measurement has met the first end of life threshold, compare the life measurement to a second end of life threshold, determine if the life measurement has met the second end of life threshold, and provide a second end of life output indicating that the life measurement has met the second end of life threshold.

A device for extracting auxiliary power from a power source installed on or associated with an implement, and supplying the auxiliary power to an auxiliary tool associated with the implement. The invention is preferably employed in the context of an auxiliary tool, e.g., in the form of a rotary trimmer, edger or the like, associated with another power implement, such as a lawnmower, wherein the power is preferably extracted from a driven member of the implement. Advantageously, the device is easy to attach/detach, is universally locatable and/or orientable on the implement, and is easily retrofittable to practically any existing implement, such as a lawnmower deck.

A battery-powered eclectic lawn mower includes battery packs mounted on a docking stations of a bus bar by way of a gravity-biased engagement. The lawn mower also includes a priority charging control logic for giving priority of charge to battery packs that have a state of charge over a threshold. The lawn mower also includes a live to drive system which alerts the user when the lawn mower is capable of moving in response to manipulation of controls. The lawn mower also includes a variable speed control which adjusts a sensitivity of speed controls such that more precise, slower speed control of the lawn mower is achieved when mowing around trees and the like.

Outdoor power equipment including a frame, a battery, multiple wheels, a cutting deck, multiple chore motors, and multiple blades. The cutting deck is coupled to the frame and has a discharge opening. The electric chore motors are attached to the cutting deck and are selectively powered by the battery. Each of the blades is powered and rotated by one of the multiple electric chore motors. A first blade of the multiple blades is rotated in a first direction and a second blade of the multiple blades is rotated in a second direction opposite the first direction.

A battery system for a power equipment apparatus including a battery, a first latch and a second latch. The first latch and the second latch can be movable between a locked position where the first and second latches are configured to engage with a mating structure of the apparatus and a released position where the first and second latches are disengaged from the apparatus. A gearing assembly can be attached to the battery and driving one of the first latch and the second latch between the locked position and the released position. A spring can engage the first latch and the second latch, the spring biasing the first latch and the second latch toward the locked position.
