A rechargeable battery assembly has a first battery unit with a first terminal and a second terminal; a second battery unit which is serially connected to the first battery unit and which has a first terminal and a second terminal; and a differential amplifier with an inverting input, a non-inverting input, and an output at which an amplified difference between the signal at the inverting input and the signal at the non-inverting input is produced. The non-inverting input of the differential amplifier is connected to the second terminal of the first battery unit and to the first terminal of the second battery unit. The inverting input of the differential amplifier is coupled to the first terminal of the first battery unit and to the second terminal of the second battery unit. The output of the differential amplifier is connected to the second terminal of the second battery unit. A coupling element with two load connections is connected between the output of the differential amplifier and the second terminal of the second battery unit. The coupling element allows the second battery unit to be charged via the coupling element but at most allows a minimal discharge of the second battery unit in the direction of the output of the differential amplifier.
