Auto Releasing ML-Series Remote Battery Switch with SPST Switching Provides 500A switching and features of current ML Remote Battery Switches, but can be controlled with SPST or SPDT switch for applications where a normally open relay is desired.  This feature means that if you are looking for a 12 volt heavy duty mechanical relay to control from a BMS this would be the one to use. Note that an intermediate relay may be required since most BMS's would not support the 13 mA coil current required.  Note also that there is an 8mA current draw when the switch is off.
