This is my first version of a portable 12v power source for use with a DC capable RC battery charger. These ten can be charged back to full using a battery chargers lead battery (Pb) setting. This should be great for weekend camping events and gets you away from using your vehicles battery. Not sure on price yet. I need to add up parts costs but expect it to be in the ballpark of about $80-$100 for what you see here.
These are very adaptable and could be put into other types of cases that could allow room for the charger in the same case or even the possibility of adding a solar charging system for long remote usage. Obviously costs would vary.
Here are the links to most of what I used here if you want to make one tryout self.
