Electrical power system in connection with a delivery vehicle having an engine, and a liftgate powered by an electric motor. Electrical power system includes a first battery, a second battery, and an alternator. Electrical power system also includes a super capacitor. Super capacitor has a first capacitor bank and a second capacitor bank, wherein each of the first capacitor bank and the second capacitor bank comprises ultra-capacitor cells placed in series. First capacitor bank and the second capacitor bank reside in parallel. First battery and the second battery reside in parallel with the second capacitor bank. First battery, the second battery and the second capacitor bank supply power to the liftgate motor. First capacitor bank is in electrical communication with the alternator and supplies power, with the alternator, to a relay start for the delivery vehicle to start the engine.
