Finally got DC/DC charger fully installed to keep my 3 new Lithium batteries and alternator safe and sound. Below are pics of finished battery compartment. 3rd battery went to right of partition wall.
DC/DC charger went on far wall since it produces alot of heat and didn't want to close to batteries even though they are not lead acid. Previous owner or someone drilled a 1 1/2 inch hole which was perfectly placed for heat to dissipate or cool air to get in. I have heard that putting a small temp controlled fan blowing on dc/dc charger improves performance. I may be looking to do in future.
Also, cleaned up lines by putting a bus bar with cover to take some load of direct battery terminal. Also added extra lenght to wires so I can take out charger or batteries without disconnect anything to get space to work in area.
HOWEVER, I made one mistake, I forgot one final step in picture of DC/DC charger, any guesses?

You forget to heat-gun your shrink wrap?
Winner winner chicken dinner. Was rushing to finish up. Also used red ferrel on black line, will just wrap the red peaking out in black tape to avoid any confusion.
Camaro, Is the "IN" wire fused all the way from your chassis battery? I see the breaker in your photo, but if that's the only protection, then that's not an ideal location...

Scott, the "IN" red wire is connected thru the Spartan fuse to a buss bar where the alternator wire is connected. The "Out" wire goes to the coach battery bank. The Victron Manual has a schematic recommending this.
I also kept the Chinnoks Eaton isolator under the hood in place as well.
I was curious if the Spartan breaker is the only protection between the Orion and the chassis battery. If so, you don't want it where it's shown in your photo. Ideally you want the protection as close to the power source as possible. I can see very little of your system, so I wanted to ask rather than assume.

Fair question, I also have the Eaton under hood isolator inbetween as well
Moving the Spartan is easy enough now that I have the tools to make my own wires. Next time I need project to play with this will be on the list.
