Abstract
A quick low-voltage rechargeable battery is switched between a charging mode and a discharging mode. The battery includes plural battery cells and a power management circuit. Each battery cell includes a battery positive terminal and a battery negative terminal. The battery positive terminal of each battery cell corresponds to the battery negative terminal of another battery cell sequentially, so as to constitute a battery cell sequence. Respectively, the battery cells connect the power management circuit. The power management circuit includes a loading positive terminal and a loading negative terminal used to connect to a load. In the discharging mode, the power management circuit switches the battery cells to a series connection state; in the charging mode, the power management circuit switches the battery cells to respectively connect to a charging source and to be charged, and the battery cells are not connected in series.
