So I'm buying a new charger sometime this week, haven't decided which one I've been looking at icharger, powerlab mostly. But I'll need a good power supply, 1000w to get full power oit of the charger I want. Iv seen how to videos on doing the big Hp power supply, and also hooking them up in series. I've seen on ebay a guy makes them for you, with bullet connectors and wraps them in carbon vynil and they look good. Rating are 12v/75amp/900w that runs about $55 bucks. There amother box that's ratings are 12.4v/85amp/1025w for around $75.

What I've researched so far is you can't get over 500w out of 12v so are the ratings listed wrong on the listing? This supply is also just a litter bigger then a dollar bill compared to the big ones I was reading about with super loud fans.
If somebody could give me some advise here I'm new to this next level of charging and want to buy a 1 time charging station I won't have to ever upgrade. I shouldnt be charging anything over 4s and I want to be able t charge quick atleast 25-30amps

I have the Team EAM power supply and have no issues charging at 40A with my iCharger 406 Duo. I run the power supply off of 120v A/C plugged into a wall outlet. I believe it is similiar to the ones you described looking at.

The mod on the hp power supply is not difficult at all if you want to do it yourself. I've done a couple of them and they work great. They only run about 25-30.

I use the carbon vinyl wrapped one from ebay with a icharger 406 duo and have zero issues charging at 40 amps.

Take a look at http://lipoconnectionsolutions.com/

Great price, great service, fast shipping. A lot of the high power rc airplane guys use his power supplies and are very happy with them.

I have one of his 12V power supplies, but am not sponsored or employed by them, just a happy customer. I also have friends charging at 40 amps on their 12V supplies.

These are the same DSP1200 supplies everyone uses, I have converted several dozen myself. Will put out 12v/60a without breaking a sweat. I charge 2x2s@40amps at the same time regularly with mine.

I've been using this for my icharger406 more than a year without any problem.http://www.ebay.com/itm/Powerlab-8-6...gAAOSwbYZXVmSY

I picked up two of the HP DPS-1200FB for $40 shipped on eBay. Took me 20 minutes to solder on bullets, and adjust the potentiometer inside to get a solid 12.8V. I spent $10 on a pair of computer power cords, and 2 1000ohm resistors. I already had the bullet connectors.

To confirm that it was working properly, I hooked it up to the electric tongue jack on my cargo trailer, and used a clamp-on ammeter to measure current during operation. I got a maximum of 68A @ 12.8V (870W)......the power supply didn't limit the amperage. That's just the max it took for the motor to lift the trailer tongue, while hooked to the hitch on my truck.

I won't do a fancy wrap on them because they'll be mounted in their own cabinet in my trailer, but for less that $60 total, I've got enough power to handle any charging needs I'll have, plus have enough surplus to power the car stereo and amp I'm putting in.

Here's a link to an article I found that gives really good instructions on how to set them up for RC, or other use.

You may already know, but this is the "pre-configured" HP DPS1200-FB power supply that we've been talking about.......

Answer - Note: as I do not know that particular power supply, but- a 12v power source can deliver those kind of amps and much more.
Look at a real car charger, it can have a setting to start a car straight from the battery charger. It is not a regulated power source, but I have used one as a charging power supply myself.

Buy This One !!

That's a beast!!
I'm actually buying a supply from a website mentioned above,
http://lipoconnectionsolutions.com/
They have the exact supply I was asking about and they have it in series at 24v and even up to 48v, but it's only a little bit more money to just buy the two of them already wired up from that site vs me buying the two power supplies and a new soldering iron, wire, connectors, ect. Lol I will buy a new soldering station after I buy this icharger tho.

Awesome power supply!! Of course I think that because I have a very similar one, but mines only rated to 600 amps lol.

In principle that is correct, the big chargers are power limited with a 12V power supply, regardless of how big it is. Actual value varies some by charger model. Ratings aren't wrong, just need to consider all of them.

It's not a power supply limit, the chargers have an input current limit. Need more input Voltage to achieve full power output. The big chargers need 24V or more, even some of the mid size chargers need ~18V for full rated power.

But if only charging 2S packs 12V supplies are usually enough. The high Voltage supplies are needed for larger packs at high Amp rates, say 6S and up.
