A distributed battery power system having a battery pack and a battery controller. The battery pack has: a plurality of cells configured to generate a plurality of cell voltages; a voltage current temperature module electrically connected to the plurality of cells; and a plurality of isolation switch sets electrically connected between the plurality of cells. The battery controller is in communication with the voltage current temperature module, and operable to: send a status request to the voltage current temperature module; receive the plurality of cell voltages from the voltage current temperature module in response to the status request; determine if the plurality of cells includes one or more problem cells in response to the plurality of cell voltages; and perform an action in response to determining that the one or more problem cells are present to prevent damage to the one or more problem cells.
