Those datasheets show creating a series pack/cell. They don't show the circuitry to then parallel the packs together.

I guess I need to do more research on this.

You seem to only have looked at the TI one, the Diodes one is for a single cell.

& if the cells are "permanently" connected in a pack, you wouldn't have individual cell protection and just have them properly balanced before connecting them in factory.

> parallel the packs together

You parallel cells, not packs.
