Abstract: A cassette (1) for a battery stack (3), comprising a casing (2) for a battery pack (4), which casing (2) is made of a non-conducting material. The casing (2) has a front side (5) with an opening (6) for receiving the battery pack (4). Preferably, the casing (2) has a back side (7), opposite the front side (5), the back side (7) being provided with electrical connections (8, 9) lead-ing into the casing and arranged to connect to the poles of a battery pack (4) when a battery pack (4) is inserted into the casing (2) through the front side (5). Arrangement of the cassettes (1) is also provided, wherein the cassettes in the arrangement is placed in mechanical connection on top of each other.
