A voltage enhanced battery module and a voltage enhanced battery assembly with the same are described. The voltage enhanced battery module includes a battery cell and a voltage enhancing circuit. The battery cell provides an original output voltage, and the voltage enhancing circuit generates a predetermined voltage difference with the power of the original output voltage to output an actual output voltage to a load. The predetermined voltage difference is superimposed on the original output voltage so that the actual output voltage equals the original output voltage plus the predetermined voltage difference. The battery cell is preferably a rechargeable Li-Fe battery cell. The voltage enhancing circuit can stop superimposing the predetermined voltage difference on the original output voltage when the original output voltage is lower than a predetermined value so that the actual output voltage equals the original output voltage. The voltage enhanced battery module is preferably used on a motor, a power tool such as a power screwdriver or drill, or an electric motorcycle.
