PowerPoles are neat little modular power connectors used commonly in amateur radio. But often, you’ve got one power source, for example, a battery, and want to power more than one piece of equipment from it. You can make a separate set of cables for each piece of equipment and run it all the way to the battery, or you can use a power splitter. Much like a standard power strip used for AC power in your home.
You can certainly buy power splitters from various retailers. There are several manufacturers with a variety of products to suit different needs. I didn’t really want to pay for one, and my needs were very simple, so I made one. Here’s how.
Take a small piece of double sided copper clad PC board. Easily found a radio shack. Run short wires from a few sets of powerpole connectors, and solder them to the board. (Obviously making sure that one side of the board is for one polarity) I for the wires, I used small chunks of standard house wiring (Romex). Tape it up so you don’t short anything out or shock yourself. DONE!
This method lets you connect as many devices as you want. Just make sure not to overload the current rating of the powerpoles themselves or your wires feeding the splitter. Make sure you throw some fuses somewhere in there too!
