In a compact Li-ion (lithium ion) secondary battery pack system, a voltage detecting terminal for detecting a recharged voltage of this battery pack can be is omitted. This Li-ion secondary battery pack system is constituted by employing: an Li-ion secondary battery; a case for storing thereinto the Li-ion secondary battery; recharging terminals exposed from an outer surface of the case; a shortcircuit preventing diode used to connect the recharging terminals to the Li-ion secondary battery, and capable of blocking a flow of a shortcircuit current when a shortcircuit happens to occur between the recharging terminals; a resistance element connected in parallel to the diode; a recharge and an output terminal connected to said Li-ion secondary battery. |
