  "textContent": "A battery system includes a plurality of battery modules each including a plurality of battery cells. One battery module includes a main circuit board, and the other battery modules include auxiliary circuit boards. The main circuit board includes a cell characteristics detecting circuit that detects characteristics of each battery cell and a control-related circuit having a function related to control of the plurality of battery modules. The auxiliary circuit board includes a cell characteristics detecting circuit that detects characteristics of each battery cell, and does not include a control-related circuit having the function related to control of the plurality of battery modules. In a battery module of another battery system, a first printed circuit board, a board holder and a second printed circuit board are attached to one end surface frame. A voltage detecting circuit that detects a voltage between terminals of each battery cell and a communication circuit having a communication function are mounted on the first and second printed circuit boards, respectively.",
