  • the presence of a protrusion on the PCB and the fixture allows the device to produce a lever effect on a battery module, thus providing a high pressure, through the mechanical urging, on the battery module. This ensures that a good electrical contact is made between the electrical contacts of the device assembly and a battery module.
