Hi,I'm looking to hook up a car battery to a portable power pack e.g. something like this
Well, yeah, since that is what the power pack is designed to use, your car battery THROUGH the cigarette lighter, a car battery COULD be hooked up directly to it. But instead of using the vehicle cigarette lighter adapter, you'd simply wire the bare ends directly to the battery. Kind of defeats the portability of it, though, since car batteries are pretty hefty. And you'd need some way to recharge the car battery. Car batteries, by the way, are not designed for discharge and recharge. They are designed for momentary heavy surges, or short term continuous use, and constant trickle charge. Deep discharge batteries, such as those used in golf carts, etc, are much more expensive.
