Provided are a battery controller, a wireless battery control system, a battery pack and a battery balancing method. The battery controller is for a battery module comprising a positive terminal, a negative terminal and a plurality of battery cells electrically connected in series between the positive terminal and the negative terminal. The battery controller comprises a voltage measuring unit to generate a voltage signal indicating a cell voltage of each of the plurality of battery cells, and a control module. The control module wirelessly transmits sensing data indicating the cell voltage of each of the plurality of battery cells while the control module is operating using a first cell voltage of a bottommost cell of the plurality of battery cells as power for operating the control module.
