The present invention relates to a battery stack arrangement () comprising at least one bipolar battery. Each bipolar battery comprises a plurality of battery cell arranged between endplates (). Each battery cell is provided with a seal () arranged around the entire periphery of each cell, and a sealing pressure Fseal is applied over the seal to prevent electrolyte leakage between adjacent cells. The battery stack arrangement further comprises a mounting frame () including: at least two mounting units () and at least one tie unit () holding said mounting units together. The bipolar battery is arranged between the mounting units (), and the battery stack arrangement further comprises at least one spacing element () arranged between the mounting units () and each spacing element () abuts against at least one endplate () and is held in place by said mounting frame () to create a stack pressure Fstack, independent of the sealing pressure Fseal. The stack pressure is controlled by the tie unit.
