A method of decoupling a battery during high current cranking of an engine comprises charging a supercapacitor bank to a preselected dc supercapacitor voltage from a battery when said battery is above a preselected battery voltage, switching the supercapacitor bank to a load and switching the battery off the load, starting the engine and supplying initial voltage and current until terminal voltage of the supercapacitor is equal to terminal voltage of the battery, switching the battery into parallel with the supercapacitor, disconnecting the supercapacitor from the load, and recharging the supercapacitor to the preselected dc capacitor voltage.. .
