    Hello Jun,

    455 can support 16 cells in series; For daisy chain, it can support 8bits device ID in theory.

    16 devices which can support 16x16=256cells should cover most of application.

    To be frank, 455's daisy chain is data-pass through architecture not reclocking as our new device bq79606, so we don't

    recommend to adopt full daisy chain by 455 devices.  Multi-drop architecture is preferred for 455 design.

    Thanks!
