@brassmonkey001, it's not quite as simple as that. The BatteryProtect is a one-way device only, which means that if you want to use it as a charge disconnect, you need to connect it in "reverse" - that is, with the charge sources connected to the "in" post and the battery connected to the "out" post; you may then configure it to disconnect in the event of high voltage.
To use it as a low-voltage load disconnect, you need to attach the battery to the "in" post and the loads to the "out" post. You cannot have a single BP serving both purposes. Current applied to the "out" post flowing to the "in" post will immediately and irreparably damage the BP, and can pose a very significant fire hazard.
It's also worth noting that to configure the BMV relay to trigger based on temperature, you will of course need either the BMV-702/712 temperature sensor connected to the shunt PCB or a Smart BatterySense on a VE.Smart Network with the BMV.
Please see the updated BatteryProtect user manual here: https://www.victronenergy.com/upload/documents/Manual-Battery-Protect-12V-24V-65-A-100-A--220-A-EN-NL-FR-DE-SE-SV-PT-TR-IT.pdf
I've done that, but only with my DC-DC charger and MPPT. I have a basic BMS with no temp control so I run the 'allow to charge signal' through the 712 relay and have that configured for temp control. So when the 712 temp sensor is too cold, it shuts off charge by disconnecting the BP100 I have for the chargers (50 amp DC-DC and 300W of solar through a 100/50). For the AC charger, I have a multiplus, so I use the two wire assistant to turn off the charger. I wired in an optoisolator to the same allow to charge signal after the 712, so it can also shut off when it's too cold.
Always have a BMS, don't use the BMV low or high voltage alarms for lifepo4 as that doesn't account for individual cell voltages. I'm only use the BMV to make up for the shortcomings in temp control on my BMS.
