Abstract
A rechargeable battery pack supplies electrical drive power to an electrically driven machining device. The rechargeable battery pack has: a plurality of rechargeable battery cells, wherein the rechargeable battery cells each have cell contacts; a housing, wherein the rechargeable battery cells are arranged within the housing; and a potting compound, wherein the potting compound protects the cell contacts from contact with water from outside the housing. The housing has a housing top part and a housing bottom part. The housing bottom part overlaps the housing top part such that the housing top part defines an outer region and an inner region of the housing bottom part for the potting compound. A casting level of the potting compound in the outer region is above a casting level of the potting compound in the inner region.
