I ran my 12 volt electric blanket as well as gaming laptop the other night. Woke up to 11.8 on the deep cycles according to my inverter display...the start module fired it up like no bodies business. I've been impressed with it as it's approaching 4 years old and the deep cycles are 3 years old.

I took Waterloo's advice and went to Batteries Plus and the knew Batteries and was very helpful. He said that they did like 90 some percent of what a deep cycle did but was also good for cranking. How did you isolate that cranking Battery from the rest as far as wiring? I do want to install a small solar panel just to keep them fresh when I'm off.
