LiFePO4 cells can expand during operation, causing them to bulge. Incorrect or insufficient bracing of the LFP cells promotes this expansion. The expansion increases the distance between the cell terminals.
When using rigid connectors with fixed screw connections, the connectors may pull on the cell terminals, which can lead to damage or destruction of the LFP cell. The distance between the terminals of the cells is 72 mm. Our connectors have a hole spacing of 75 mm, which provides 3 mm of play to compensate for cell expansion. This keeps the terminals free of mechanical tension throughout their service life.
