A battery system having at least one battery string of more than two batteries connected in series, a charge equalization circuit, and a relay matrix. The plurality of battery strings each comprise more than two batteries connected in series and are connected in parallel. The charge equalization circuit is capable of equalizing the charge on any pair of series connected batteries in any one of the plurality of battery strings. The relay matrix is operatively connected between the charge equalization circuit and the plurality of battery strings. Based on at least one of a voltage and a current of any one of the batteries, the relay matrix is operated such that the charge equalization circuit is connected across any one of the pairs of series connected batteries in any one of the plurality of battery strings.
