Switching the Orion DC to DC charger

I would like to control an Orion DC to DC charger with the auto's battery voltage. I'm charging a 24v battery with a 12v auto system.

I want to turn on the charger when the auto battery voltage gets above 13v, thus indicating a running engine and a near fully charged battery. I don't see a recommended product anywhere on Victron's site?

I was thinking of using a mosfet switch like this

Anybody used a similar type switch with success? Anything I need to look out for?

I just found the engine run signal under the drivers seat. I will use a relay to send that signal to the ORION. Much better than detecting a voltage change.
