Abstract: A battery staging system including a first and second battery in operative communication with each other and an electrical load; a boost controller in operative communication with the first and second battery; an inductor in operative communication with the boost controller, the first battery, a ground and the second battery; the inductor connected between first battery and ground for a predetermined time to obtain an inductor current; the boost controller is configured to pull a first battery current and drive it into the second battery responsive to the predetermined inductor current; the inductor being connected to the second battery responsive to the inductor obtaining the predetermined inductor current; the inductor is reconnected between the first battery and the ground before the inductor current reaches zero; and the boost controller configured to pull the first battery current from the first battery until the first battery voltage reaches a target voltage.
