I would NOT recommend pulling 180A through any of these.
Having read the data sheet (and consulting electro engineers gut feeling) the spec wrongly assumes that heat will be dissipated through copper in the connectors. Look at how the shunt resistors are stacked on to each other in the 180 version - anyone seriously believes these resistors will allow for 2 W each?! Maybe for very short moment, some seconds. If not extremely well cooled, the entire board will soon become severely overheated.
Sorry, but I cannot believe these sensors has been tested at 180 amps…
No public wish lists :(
