The first and second batteries (31, 32) are electrically connected in series to provide power to the prosthesis, while the third battery (33) is electrically connectable through the switching means (36) in parallel with either the first battery (32). The third battery (33) is electrically connected by the control system in parallel with whichever one of said first battery (31) or said second battery (32) has lowest voltage.
