It looks like RS485 and CAN have the same connector unless I am missing a key or something. I don't need the box, but I would get a cable for $7.
@Haugen -- did you manage to get the connector and its protocol? I have a similar variant (0.6A balancer/100amp bms). My unit also has both the CAN/RS485/GPS ports but not sure where to get the connector box or how to get its protocol.
Any help is great, thanks.
