Seems like a very inefficienct system. If you want heat, just run resistance heat directly from the EV voltage. That is 100% efficient and costs nothing in complexity. Just series whatever number of 120v heater elements in series is needed to reach the pack voltage. And of course switch to DC fans. Or if you like the existing housings, just run a cheap $25 25W inverter to still run the fans on AC, but the elemetns on the DC. And of course bypass ALL switches, and contacts, and cutouts, and themrostates with RC sunbbers so they don't burn out on the first time they are used.

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.
