Abstract

A battery assembly (10), in particular for use in an electrical propulsion VTOL aircraft (100), comprises a plurality of battery stacks (12), and a venting system (59) with a venting plenum (62), each battery stack (12) comprising a plurality of battery cells (50) stacked in a stacking direction (V) and a pressure relief safety device (30) configured to discharge gas from the battery stack (12) into the venting plenum (62) when a pressure inside the battery stack (12) exceeds a given threshold, and wherein the battery stacks (12) of the assembly (10) are arranged side by side along a row direction (R) perpendicular to the stacking direction (V), the pressure relief safety device (30) of each stack (12) being provided on a battery stack wall (19) extending in parallel to the stacking direction (V) and to the row direction (R), wherein the battery stack walls (19) are not formed as separate components but as a common continuous wall (21) attached to and connecting all the battery stacks (12) of the assembly (10), and wherein the venting system (59) is a venting cover (60) sealingly attached to and covering the common continuous wall (21).
