Buddy, You can use one of the Schottky diodes that is ideal for this architecture, typically they come in a block with 2 diodes integrated and ready to mount to a heatsink, the only thing you need to take care of is to insulate the diode housing from the chassis of your vehicle as the housing has the output to the + of your battery while the chassis of your vehicle is always connected to the aux battery negative. You can find these diodes searching Ebay with "Schottky 200A" or "Schottky CNQ" Examples are the IR 203CNQ100 (100V, 200A) or 301CNQ045 (45V, 300A)

I am attempting to hook up two DC to DC in my car along with a battery for my Aux 12volts. Yes, I know that seems excessive but I need the extra to run my 12dc to 110vac inverter that runs my heaters. It has been recommended here on the list serve that I place a diode on the output as to not give feedback to either of the DC2DC. My problem is I don't know what specifications I need to use. Plus if someone could also tell where I could purchase it I would be most appreciated. I know that there are quite a few of you on the list that would probably know this off the top of their head. Here is some info that I know. Battery is a Durcel AGM SL34M (20 amp hour rate - 55, Reserve Capacity:120 DC2DC #1 Zivan NG1 - 50amps DC2DC #2 Azure DC-DC750 - 56amps DC2AC inverter Cobra 2575 - 2500watts cont. - 5000watt peak 110vac - 1500 watt Heater Thanks for your assistance, Buddy Mills buddymi...@cox.net Look mom, no gas. http://www.evalbum.com/2887 Disclaimer: No animals were harmed or killed in the process of writing this email.
