Installed the Victron Orion-Tr Smart non-isolated DC to DC charger... removed my Blue Sea 7622 ACR. just a quick question: In the settings. Default is LiFePo4 

Is there a specific voltage to set the Input Voltage at? As it is adjustable (as is the shutdown detection voltage).

I looked at those too when I installed mine.  Set it low enough so that it would never try to engage if your starting battery was draining... anything less than 11.5V looks dangerous to me, so that is where I set the bottom number.  Top number I set to something above my fully charged Optima Yellow top sits at... so that if it is higher than that, the alternator must be running.  13.8v works for me.

 

I'm not really sure why victron has two settings here. The engine shutdown detection setting would suffice I would think?
