Me and another guy made some good progress on updating the charging panel at our RC airplane flying field.

RC battery chargers work off 12 volts, and over time the solar panels and batteries have been upgraded. As more people are flying electric airplanes, the old charging station would get a little crowded sometimes... not to mention it used small gauge wire and the wiring looked like a rats nest. It had questionable solder joints everywhere, and generally was not up to the task of handling multiple people charging at once.

The new panel about triples the number of charger hookups, and is also about 3 times larger. Lots more room to spread out.

The wiring in the background is much larger. We used 6 gauge wire (~4.1mm) for the rails, and 12 gauge (~2mm) from the rail to each port. Each binding post can handle 30 amps. The combined load for the whole panel could probably go as high as 100 amps... though I doubt it'll ever see anything close to that.

I also installed a display that shows voltage and total current.

We still have some finishing touches to do, but it's already a huge improvement!

There's another member who is more knowledgeable and equipped to handle the rest of the finishing touches. Much larger wires are needed from the batteries so we can have a larger inverter to run laptop computers and monitors during events. He has a big crimping tool to handle the large lugs. He'll come later and install DC circuit breakers, tie everything in to nice bus bars, etc.

Sounds like you've made good progress on making everything neater and safer for your RC club ๐Ÿ‘๐Ÿป
