I'd not recommend that, unless you have a separate battery for starting the engine. You might shut off the car with just over 10v in the battery, and not have nearly enough juice left in the battery to get it to start again. So, either a separate starting battery, or a supercap and some circuitry to charge it higher than the 10v it would get from the deep cycle battery.

DJ: Nice, well-thought through mod you have done. I was considering something a bit more simplistic to do a similar job, but with a proper schematic in front of me to follow, I could more easily just duplicate your work and tune it to my needs. Love the idea of tricking the alternator to put out less than full charging voltage. Thanks!
