Abstract
A battery-powered system includes a battery pack () connected to an electrical equipment (). The battery pack includes a first positive electrode terminal (), a first negative electrode terminal (), a first communication terminal (), a first data input circuit (), and a first limiting circuit (D; D; D) that limits a flow of electric current in a direction from the first negative electrode terminal to the first communication terminal via the first data input circuit. The connected equipment includes a second positive electrode terminal (), a second negative electrode terminal (), a second communication terminal (), a second data input circuit (), and a second limiting circuit (D; D; D; D) that limits a flow of electric current in a direction from the second negative electrode terminal to the second communication terminal via the second data input circuit.
