Orion TR Negative/ground same for in-/output?

Hello,

I just bought an Orion TR DC-DC charger isolated with 9amps to charge the lithium batteries of my trailer using my tow vehicle.
Is it possible to use the same negative/ground for input and output? My tow vehicles ground runs to a ground bar in the electric box of the trailer and is therefore shared anyways between tow vehicle and trailer.

Also, what would be the best output voltage to charge lithium batteries?

Thank you,
Christian
