A rechargeable battery has a plurality of cell strings each having a plurality of rechargeable electrochemical cells connected in series, and a plurality of charge regulators each connected in series with one of the cell strings. Each charge regulator is adapted to limit a charge voltage or current applied to the cell string based on a determined top-of-charge voltage for each cell string. In an embodiment, the rechargeable battery has a monitoring system to sense an operating parameter of the cell string and determine the top-of-charge voltage, and each of the charge regulators includes a charge voltage controller in communication with the monitoring system. In another embodiment, the rechargeable battery has discharge regulators each connected in series with one of the cell strings, and adapted to limit a discharge voltage or current from a given cell string based upon at least one monitored parameter of the cell string.
