A battery monitoring system for monitoring cells in a battery bank where the cells are interconnected between output terminals, the system having: a controller having a plurality of current sinks that are operable to supply an alternating current of a predetermined magnitude to the bank such that the predetermined current is caused to flow through the cells; and a plurality of transducers (27-38) arranged in series with one another and coupled to the controller, wherein each transducer (27-38) is coupled to electrodes of an associated said cell and each said transducer (27-38) being adapted to measure cell characteristics and the impedance between an electrode of an associated cell and a link (52) connected to the electrode, at least some of the plurality of transducers (27-38) being powered by cells of the bank, the transducers (27-38) functioning to transmit information to and receive information from the controller, the transducers (27-38) measuring characteristics of the cells when the predetermined current flows through the cells.
