(1) Cell balancing must be controlled to limit the current based on the absolute maximum allowed current, and to avoid exceeding the recommended device operating temperature. This can be accomplished by appropriate sizing of the offchip cell input resistors and limiting the number of cells that can be balanced simultaneously.
