The present disclosure discloses a battery equalizing circuit, which comprises a first battery unit, a second battery unit, a current detecting resistor, an equalizing inductor, a first control switch, a second control switch and a feedback control circuit. The first battery unit is connected in series with the second battery unit. The first battery unit, the current detecting resistor, the equalizing inductor and the first control switch are electrically connected with each other to form a first circuit loop. The second battery unit, the current detecting resistor, the equalizing inductor and the second control switch are electrically connected with each other to form a second circuit loop. The feedback control circuit is connected in parallel with the current detecting resistor to detect a voltage drop across the current detecting resistor, and switch between the first and the second circuit loop so as to make an equalizing current substantially constant.
