Smart Battery Protect Relay voltage range

What is voltage range of the relay H on the 12v battery protect? I would like to toggle the battery protect on/off with the load out of a 48v Smart Protect.

Anybody? I tried connecting the L terminal from the MPPT load terminal to the L terminal on the Battery Protect but that seems to enable the Battery Protect permanently, I.e. even if the load terminals are disabled the Battery Protect remains enabled.

Have a feeling, could be corrected.

Since the remote h/l was designed for a signal from the battery it is protecting. It would be the voltage range of the battery it is connected to.

Max operating voltage in 24v mode is 35v.
