An electric powerhead includes a housing including a mounting assembly, wherein the mounting assembly includes a mounting plate and a mounting insert. The mounting plate includes a shaft opening and a plurality of first openings arranged in a standard vertical shaft engine mounting pattern and the mounting insert includes a plurality of second openings aligned with the plurality of first openings. The electric powerhead further includes an electric motor positioned within the housing, wherein the electric motor includes an output shaft that extends through the shaft opening of the mounting assembly and wherein the output shaft is configured to rotate about an axis of rotation.

Vertical shaft electric powerhead

An electric starting system for an internal combustion engine is provided. The starting system includes a battery, a starter motor, and a blower housing. The starter motor is configured to start the internal combustion engine. The battery is integrated with the blower housing.

Electric starting system for an internal combustion engine

An electric starting system for an internal combustion engine is provided. The starting system includes a rechargeable battery, a battery receiver, and a starter motor. The rechargeable battery including a battery housing, internal circuitry housed within the battery housing, two voltage output terminals, and an enable terminal. The battery receiver includes a battery receptacle configured to receive the rechargeable battery, two voltage output terminals, and the enable terminal. The starter motor is configured to start the internal combustion engine. The internal circuitry is coupled to the enable terminal and configured to enable and disable an internal switch to provide power to one of the two voltage output terminals, the internal circuitry monitoring at least one internal condition of the rechargeable battery for a fault condition. The internal circuitry disables the internal switch upon detection of the fault condition.

An electric starting system for an internal combustion engine is provided. The starting system includes a rechargeable battery including two voltage output terminals and an enable terminal, a battery receiver including a battery receptacle configured to receive the rechargeable battery, two voltage output terminals, and an enable terminal, a starter motor configured to start the internal combustion engine, and a continuous duty electrical load. The voltage output terminals of the lithium-ion battery and the battery receiver are configured to connect to complete a circuit between the rechargeable battery and the continuous duty electrical load when the rechargeable battery is attached to the battery receptacle.

An electric starting system for an internal combustion engine is provided. The starting system includes a rechargeable battery including two voltage output terminals and an enable terminal, a battery receiver including a battery receptacle configured to receive the rechargeable battery, two voltage output terminals, and an enable terminal. Each of the enable terminals is positioned remote from the related voltage output terminals. The voltage output terminals of the rechargeable battery and the battery receiver are configured to connect to complete a circuit between the rechargeable battery cell and the starter motor when the rechargeable battery is attached to the battery receptacle. The enable terminal of the rechargeable battery must be connected with the enable terminal of the battery receiver for the rechargeable battery to receive an enable signal to allow the rechargeable battery to provide power to the starter motor to start the internal combustion engine.

A starting battery for use with an internal combustion engine including an electric starting system with a starter motor is provided. The starting battery includes a battery cell and a control system including a timer and configured to operate a starter motor of an internal combustion engine. The control system is configured to actuate the starter motor to start the internal combustion engine in response to a user input and deactivate the motor after a predetermined amount of time measured by the timer.
