This invention relates to an active battery pack for use with two way radios. State-of-the-art battery operated radios use linear voltage regulators to generate a regulated voltage from the battery voltage. This type of regulator wastes about 30% of the battery power (l-5/7.5) in generating a regulated 5 volt supply from a nominal 7.5 volt battery. This power is dissipated in a regulating transistor.
