I say for a power supply, buy a used Compaq or HP or DELL server power supply off eBay for cheap cheap and use that.

I personally bought these two DELL power supplies for $15 off eBay. They are 550W each. I thought I would run them in series as to get me 24V at 1100W but once I got my charger and did some research, I didn't need all that, so I just keep the other as a spare.

Here is the basic HowTo I followed. His site has info for tons of other power supplies. I feel confident that the power supply is QUALITY, compared to some of the ones that are for RC use are just Chinese crap. These sell for cheap because they are used in obsolete servers. They are still great power supplies and when brand new and the servers they went in were state of the art, these were insanely expensive.

Here's the link to my auction I won before and a stock image of a power supply.

I use a Hyperion EOS 720i Super Duo3, which is their flagship dual battery charger. It has a maximum 500W per port (totally independent of each other) and 20A per port. Charging 2S (what I run), I can charge 2 5600mAh Turnigy Nano-Tech LiPo's (8C charge rate max) at 20A each and it takes about 27minutes per battery to charge and balance. Probably 5 minutes or more faster to eliminate the balancing ,but I am in no rush.


I foresee an issue within the 12V at 550W not being sufficient if I was charging 4S or 5S etc. batteries at the same time. I only own 2S anyhow, so it's not happening now. IF I get to that point, I'll take the other one and make it 24V 1100W in series I suppose...
