I think I will rent a space and sell some power supplies if there is any interest here in this thread.

12V 12 amp - $20.00
12V 41 amp 500 watt - $50.00
24V 41 amp 1000 watt - $110.00
All units are used server supplies that have been modified for RC charger use. The 41 amp server power supplies' datasheet shows an expected life expectancy of 200,000 hours at max watts. Outside of lightning striking your house when you are charging, these should outlast you.
Also, all pictured supplies are plug-n-play. Just plug your charger to the 4mm connectors, plug supply/supplies into your outlet and charge away.

Why 24V? Some chargers like my FMA Direct PL8 are rated at up to 24 volts (or higher). I can charge batteries with a 12 volt input at half the amps of what I can charge with a 24V input.

Also have about 110 of these:
NEW - 12V 17 amp 210 watt- $30.00 (not pictured)
These will come with a power cord but you will have to screw it to the supply and convert the screw outputs to accept your chargers connectors (usually 4mm bananna type connectors).

I own one of his power supplies and LOVE IT. My Hyperion 730 can take 24v and I use it to charge large 4s packs parallel and run my GT Power Quad charger on the 12c only at the same time. I can charge for a day of flying in about 1 hour.

Good money spent on these

I can vouch for Rampman's power supplies as well, I have the 24 Volt array, and power 2 Hyperion Duos charging 4 6S batteries at 10 amps, and two more Common Sense balance chargers plugged in on the 12V side, charging Rx and Tx batteries at 2 amps each, at once, and it doesn't even break a sweat!

I can make one out of server power supplies. Have to float the ground like on the 24V ones; its just safer that way.

You WILL need a dedicated 120V 20A drop or two 15A outlets, one from each leg of your panel.
41A x3 in series = 41A and >1500 watts.

Can a household outlet handle that much?

Will settle for a 24V setup. Don't need to charge a 14S battery at 30 AMPS. Rick you want a Christen Eagle don't you.

Bob, your home probably has 20 amp at the garage outlets, and would be OK as long as your not running something like an air compressor on the same circuit. If Rick makes up a 36 Volt power supply, I have a meter that will read actual amperage of the draw.

Is there a way to test for this besides licking my fingers and sticking them in the outlet?
