For Sale
New 47A 12.1V power supplies from Featherpower.

These are like the 42A power supplies I sell on my website:
http://www.feathermerchantrc.com/
and here:
http://www.rcgroups.com/forums/showthread.php?t=1051873
They are about the same size but they are 47A and the fan is louder.
I am selling them for $40 + $10 shipping = $50 in the Contenital US.
They'll go USPS Priority.

I accept PayPal to feathermerchantrc@sbcglobal.net

How are the supplies wired in relation to the casings and ground? In other-words, is the 12V side floating or tied to the case on the negative side of the 12V?

If floating, or able to make floating, this would lend itself to wiring two supplies in series for 24V output to power those higher watt chargers (such as Hyperion) that can take advantage of higher watt output through higher voltage input without having to take measures to stop 'ground loops'.

Thanks

The grounded side of the power supply is tied to the case and the ground wire of the plug. See my blog where I connected 2 similar power supplies in series for 24V. There is also a thread in Batteries and Chargers about putting 2 power supplies in series for 24V.

OK, thanks for the heads-up blog. I understand how you configured the supplies.

my set up

I just copied someone else's idea. Went to Radio Shack and bought a small project box, two sets of female banana plugs, some wire, connectors, and solder. It took all of an hour to put it together. The box is stuck using double sided tape, with a round of filament tape to be sure. I wired it up on the box end, tinned the wires on the other end, flattened them, and then soldered them to tabs on the power supply.

I don't see the 47amp on your website and the 42amp says $55.00 shipped not $45.

I'd like the 42amp for $45 shipped if still avaliable. Thanks.

I'd use 13ga minimum. You'd be surprised at the voltage drop.

I'm going to use 12G Deans Wet Noodle wire I have already and some EC5 gold bullet connectors. Then cut my CellPro 10 feed wires and make it interchangeable with the EC5's and the battery clips for the field battery.

Deans 12g is an excellent choice.
I prefer a polarized connector like Deans.

I got mine today and got everything setup. So far so good and it takes up much less space than the old Pyramid 10amp box. I used Deans 12g Wet noodle wire and EC5 gold bullet connectors.

Thanks!

The smoke detector is for the powe rsupply. LOL
Nice setup. Large guage wire is important now that we're charging more than 3S 2100 packs.

Record fast shipping!!! Thanks bro you are the best.
I picked up a project box and some banana connectors. Going to follow some of you guys. Looks good to me
Has anyone successfully put a power switch on this power supply yet? I really want to do it.

A dedicated power strip could get the job done easily.

A 7.4V pack @20A will draw 8.4 X 20 / 10 = about 17A No problem.
An 18.5 pack @10A will draw 21 X 10 /10 - about 21A Noproblem.

I have plenty.

Why 4Ga wire?

You could strip it back about 1", split it into 2 then tin those, flatten them with pliers and push them into the terminals and solder them in. With wire that large and stiff you may need some sort of strain relief to keep from breaking the terminals.

I want the option of not having the charger and PS in the same area and I read that big cable is needed depending on the run length.

Big cable is needed of you want to run a long distance. It would b a lot better, cheaper and easier to just use a 120V extension cord.

You saying to use the cable for its wire between the charger and PS or to move the PS closer to the charger?

DC current has great losses over distance. AC does not. That is why those huge transmission power lines are all AC. Just ask Mr. Edison. He tried to do the DC thing without much success.

So yes, PS close to charger with short leads. LONG AC wire to power the PS. Life is good.
