The device has a carrier for supporting a set of power cells (2a-2d) e.g. batteries, connected in series with each other. Each power cell has a positive terminal (3) and a negative terminal (4), and an electrical contact (7) is provided for each terminal at the carrier. The contact connects the power cells with connection points for power extraction. Each positive terminal and the corresponding negative terminal are electrically connected with each other by a switch (8). The switch is designed such that it is automatically disconnected when inserting the power cells. |
