Hello manipulators. Is there a way to use one 12 volt battery and make two seperate/isolated 12 volt power sources from it with some sort of circuit? Or is it best/cheapest to just use two batteries? It just seems more practical to use one battery and some sort of circuit to turn one power supply into two, to use as if it were two batteries. Any ideas or suggestions leading to a practical, cheap, easy solution is welcomed. Thanks
