Question
So, what ELSE can I do with 3000 watts of 12v - 30v dc?

I've finally got my two JD200 server power supplies all modded up and finished proper. So I can now charge at full speed with two PL8s at the same time. But what else can I do with such a powerful DC supply? Seems like there ought to be something cool to do with it besides charging batteries. I came up with HAM radio, and not much else. Any suggestions?

Wow! Perhaps you could process aluminum or do some arc welding.

Trust me, it comes in handy in the summer time. My case has 4 external USB ports so I can keep my phone charged, WiFi hotspot powered, etc. In the summer though, it is nice having that much power because as an example, I might be flying my 700 heli (using 2 x 6S 5000 packs for one fight) and my friend might be flying my Carbon Cub (another 6S 5000 pack) so you can charge about 7 of those packs in about 15 minutes. Translated no waiting for batteries to charge

As far as I know, you can't arc weld with 30v DC. Not sure about processing aluminum. I'll look into it.

And, yea, great for charging batteries. No doubt.

Excerpt from above:
Q: What voltages are used in the arc welding process?
A: Arc welding involves open circuit (when not welding) voltages which are typically from as low as 20 volts to as high as 100 volts.


And, yea, great for charging batteries. No doubt.

You can run a whole lot of LED Christmas tree lights and your doorbell too.

Power your electric motors directly from power supply.

Get a high power 90 mm edf to max out the power supply.

Cut your own foam cores.

Cutting foam cores sounds interesting. I'll have to look into that.

You can weld with 24 volts dc... you can weld sheet metal with 18 volts, but those power supplies wont do either, not nearly enough amps....
