A starter motor arrangement comprises a battery, a first starter motor including a first pinion and a second starter motor including a second pinion. The first starter motor is connected in series to the battery and the second starter motor is connected in series to the first starter motor. Accordingly, the battery, the first starter motor, and the second starter motor are all connected in series. The first pinion gear and the second pinion gear are configured to engage an engine ring gear when electrical current flows through the first starter motor and the second starter motor.
