I would be very surprised if DeWalt does not have a BMS on their Lithium packs, all power tool packs with Lithium that I have opened always come with a BMS which both checks every cell and turns off any current flow above max and under min voltage levels.
The last DeWalt lithium pack I saw open did indeed have a BMS. It was the usual switchable shunt across each cell. In fact, most of the controller was inside the battery pack too, rather than in the tool.
