On the battery positive and negative terminals in the unit there are two nuts per terminal. Is the intention here to sandwich the M8 ring connector between the two nuts or should the M8 ring connector be placed directly onto the PCB contact and tightened down with the two nuts?
In the datasheet it looks like the M8 ring terminals are sandwiched between the two nuts as in the below image. Does having a nut below the M8 ring terminal not just introduce extra resistance in the circuit? Possibly very little resistance which may not be an issue. Maybe the idea here is that the two nuts offer more surface area for current to flow when the sandwich method is used. Anyone able to offer advice on the correct way to install the M8 ring terminals on this device?
