A method of supplying electrical power to a medical device includes discharging a first external battery to output electrical power to a second external battery. Distribution of the electrical power received by the second external battery is controlled to simultaneously charge the second external battery and output electrical power from the second external battery to supply electrical power to the medical device. ## Claims ### Claim 1 A medical system comprising: a medical device configured to be worn by a user or implanted in the user;
