This would work well I belive. It will do 2 batteries at once. Plus I t had its own power supply built in with 200 watts of power on each side. It is on your higher side though. Might be worth a look. Chuck

Take a look at either icharger or Powerlab combos at
buddyrc.com
or progressiverc.com

Get the most Watts you can afford. This one is 500 watts for $250
http://www.progressiverc.com/the-su...500w-combo.html

That is both charger and power supply. 500W is a decent amount of power for 6S 5000's.

The only other thing you'll need is charging and balance cables to fit you batteries. I use the 6-way parallel cables and charge two 6S 5000's at once. They have cables for most every battery connector out there.

Power supplies aren't just for helis.

Don't they have electronic equipment suppliers in Europe?

Once you figured out what you want you may want to take a look at the used sections to save some money.

You choose a power supply by looking at the specs for your charger. The 3010B has this spec.
Maximum charge power capacity: 1000W (at >23V; 500W at 12V)
Input voltage range: 4.5-38V DC

So notice that you need more than 23V to get full power but you have to be less that 38V.

Basically you need a 24V, 1000W power supply which would be rated for up to 42Amps. Power=Amps*Volts so Amps=Power/Volts so 1000W/24V=42Amps.

Once of the reasons I suggested getting a combo is that your store will pick a matching power supply for you. Hopefully you have vendors in Europe that do this. A lot of people find "server" power supplies. Maybe you can ask other guys in your country where they buy stuff.

Here is a source in Germany for the Mean Well SE-1000-24
http://www.mouser.de/ProductDetail/...4YTAQMbSQ%3d%3d

That is the same 10000W power supply Progressiverc sold me in my 1000W combo. A slightly better supply would be the Mean Well RSP-1000-24.

Mouser is a major worldwide electronic distributor. Not a Hobby oriented company but they are fine to buy from.

Should take 35-50 Minutes depending on how low the charge is when you start.

Local Hobby Shop sells this setup in the 110V power supply version and a friend has the Double Tap charger he uses with the PS.

Being new to the charger topic , maybe I can help with some random stuff.

A lot of great suggestions above, might not see where there coming from.

Dis-Charging rates.

Packs will have a discharge "C" rating, for example 6s5000 35c. This means you can discharge that pack at 35 times the "c"apactiy of the pack. 5000mah = 5amp x 35 = 175 amps.

Same goes for the charging rates, these are typically much lower. Good packs (gens ace , etc ) will typically be rated 5c charge. That means if you have the charger that can do it , you can charge that pack at 25 amps.

In reality charging and discharging at max C ratings will result in lipo with a short lifespan.

I like to pick a lipo that will do the job at half it's rating, charge at 2c mark (all the power I got on tap)

Now lets get into the charger stuff.

Dang .. more math lol

Amps x volts = watts.
watts / volts = amps
watts / amps = volts

Worth noting that there are some losses in real life , but there not huge and it's makes it easier to see the train of thought.

Typical charging times :

charge at 1c = about 1 hour
charge at 2c = about 1/2 hr

(I don't really have the power to go past 2c myself but from what I've read you need to go with a 4c charge to get 15 min. This is a bit rare as going much past 2c is hard to supply power to do and typically hard on batteries)

So lets get that 6s 5000 back out and hook it up to the power lab mentioned earlier ( 500watt charger )

500 watts / 22 (6s) volts = 22 amps. ( about 4.4c ) - 15ish mins

Lots of folks like to parallel charge 2 packs at once

500 w / 22 v = 22 amps (10000mah now ) = about 2.2 C - 30 ish mins

The power lab is a popular choice for it's high output. Most will parallel 2-3 6s5000 packs with reasonable 1/2hr to 1hr charge times. I don't own one myself but I suspect to get 500w charge rate you will need 24 volts input (typical for high output chargers). Worth noting it can still be run on 12v car battery but the output drops to 250w. Also worth noting that charging off the car for any length of time on a high output charge may result in a long walk home.

Same math on the power supply.

That meanwell mentioned above is a good unit. 1000 watts at 24 volts. With the above formula you can pull 41.6 amps out of that supply.

This is where your going to see the worst losses. 40a going into charger = about 20 coming out. Gets worse as you go up in cell count. I charge 14s packs and it takes 24 amps to charge a 14s pack at 8.

The meanwell is a good supply , but with all good stuff comes a good price tag. There expensive.

There are other hobby grade supplies out there (efuel /charger ) that also fetch some good money.

If your a little handy with some basic soldering tools and such you can use a computer server power supply to power your setup. These are a lot less to buy and deliver a lot of power.
A nights research and poking around the forums (rcgroups has server power supply thread covering a lot of models and how to get them up and running) will save a lot of cash to get a better charger on board.

My server power supply setup is a bit old as I did it a while ago. Since then there have been better ones come out. Mine are working great and still will do the job.

I bought 2 of the dell 6650 server supplys on ebay for $100 Canadian shipped to my door. A nights worth of tinkering I had them up and running ( solder some power leads on , make up a little switch harness to turn on supply). Now I have 72 amps to play with for $100.
The dell 6650's are a bit larger and heavy (8lbs each).

Last winters project was to further mod the power supplies to up there voltages to a total of 28 volts and I fitted them into a stanley fatmax toolbox with fans , amp and volt meters for ac and dc side. Looks nice. Then I fitted 3 of the hyperion 1420 chargers on a shelf in the toolbox. Now I can charger 3 14s 5000 mah packs in about 35 mins. Works great , 35 mins gives me a chance to look over the heli's ,check and charge up rx packs, and clean up hobby room as it's always a mess.

Hope this helps with some background info to select the right parts for now and the future.

My charger of choice is the hyperion 1420. Will charge up to 14s. I run all 14s packs and don't do the parallel charging method.
I got them for $135 Canadian , sweet deal for a 500w charger (on 24 volts of course )

What goes up will come down.... one way or another !
