1. A structure for a battery pack for supplying an electrically driven work appliance with electrical drive power, the structure comprising:
a number of cell holder parts, wherein the number of cell holder parts is designed for holding battery cells,
wherein
the number of cell holder parts comprises at least two cell holder parts,
at least two of the cell holder parts are designed for arrangement together in a holding arrangement and, in the holding arrangement, for jointly holding the battery cells,
the cell holder parts, in the holding arrangement, jointly form at least a predominant part of a filling mould,
the filling mould is designed for filling with a protective material for enclosing at least a part of a battery pack electronics unit, and
the structure has at least one cast assembly, wherein the cast assembly unites one of the number of cell holder parts and at least one casted-in cell contactor, wherein the cell contactor is designed for contacting at least one cell terminal of at least one of the held battery cells.
