please describe your equipment? most epia power supplies, like the m1/m2-atx and opus can survive cranking. how new is your battery?
if you're running an inverter you should look into tank circuits (adding a wheel chair battery to help survive cranking)
I'm using one of those mini E-Vectra PCs being power directly from the battery by way of an inverter.
What I really want to do is locate the pc in my trunk, but I don't know how to connect a start up shut down controller.
I use an 700 watt (1000 watt max) vector inverter with an diehard gold battery and I survive cranking no problem. I just brought a startup/shutdown controller, but pretty confusing to me. I asked around about hooking it up but no one seemed to want to help. Here is a link to my thread...
