hyperion duo
 

Do i need a power suply to run the duo in my house ? If so were do i get one?

This is the one I ordered to use with my Duo:

I haven't received it yet...hopefully wednesday.

That PS is good for 14v @ 23A, or 322w. Chargers being around 80% efficient will eat up some of that, but should be good unless you plan on charging high cells counts at high current.

where do i get that one

From the link in ssspconcepts post... :wink:

I have the ofna 18amp ps and its more than enough to charge a 6s 5000 pack which in our hobby is as big as they get

So the max for the Duo is 180w per side, works out to 12.85 amps at 14v, is that right?

To use the full potential of the charger 25-30 amps is needed then....?

Actually, if you wanted the full 180w+180w, you'd need 32A @ 14v (figuring 80% efficiency). But really, what batteries are you gonna charge to reach that level??

I have 2 2S FP 4900s and 2 2S MA 6000s Brian. The FP 4900 say they'll take a 2.5c max charge rate which works out to 12.25 amps, I don't think I'd usually charge much over 1.5c, but I only want to buy the PS once and be happy is all. I don't think I'd go over 1c on the Max(fill-in-your-own-insult) packs.

I saw recently a Pyramid 30 amp PS for $100, first thought I had was "they're still in business?" Sounds like a great deal, but knowing Pyramid's quality from car audio, I have to wonder if it's one dirty (like a cheapo 110v welder) P(o)S...

What would be your pick in the over 25 amp category sir?

BTW I stink at mah/time figuring, but how long would a 2S 4900 take to charge at 12 amps?

24.5 minutes.

4.9Ah X 60min = 294Amp-minutes.
294Amp-min / 12A = 24.5 minutes.

Wow no kidding! That's almost A123 fast.

Thanks Brian. I'm gonna research more on hi amp PS's. I'll be buying the Duo from Mike in the next weeks, I am hung up on a PS tho. Don't really want to pay much over $400 for PS and Duo but my buddy's PolyCharge 4 ain't cuttin it with a 3 amp max lol.

remember charging a lipo at more than 1c you will shorten the life of the battery, and dont feel you need to have the full 180 watts per side...130 watts will charge a 6s 5000 pack

Well, keep in mind that charging 4900mAh batteries at 12A is almost a 2.5C charge rate, which may not be the best idea depending on the particular battery. Plus, if the pack has any kind of imbalance, it would be really hard for any balancer to equalize the cells in that short of time, and you run the risk of one or more cells getting beyond 4.2v before the CC/CV threshold.

Generally, 1C works fine and runs a little over an hour to charge a fully depleted pack, so that's not bad really.

You don't absolutely NEED a super high current PS.

If you are just going to charge a 2s 4900mAh pack at 1C, you only need a PS capable of ~4A @ 14v (or ~4.5A @ 12v).

If you want to charge two 2s 4900mAh packs at once at 1C, you need double that (~8A @ 14v or ~9A @ 12v).

If you want to charge two 3s 4900mAh packs at once at 1C, you need 11A @ 14v or 13A @ 12v.

As the pack capacity and/or cell count and/or charging C rate goes up, so does the power requirements. You could get by with a cheap 12v supply for now, but then upgrade later when you power requirements increase, but it tends to be more expensive in the long run...

Why would you charge it at that? Should never charge over 1c which in your case would be 4.9 amps.

I run a ps from my superbrain 989 and I charge two 2s 8k lipos at 8 amps a piece with ease.

"tends to be more expensive in the long run" - That sums it up Brian, I have wasted enough $ by doing it cheap "for now"- but to answer Jeremy's question.. I just have to push the envelope. :) Really I want to be able to charge 4 packs at once in a pinch with parallel adapters. Obviously I can't balance charge 4 at once, but I have a TP balancer. The Duo is an awesome charger from what I hear, I want to maximize it's versatility, and I'd rather have more than I need rather than just enough, or not enough.

Well then, prepare to pony up the bucks for a decent 40A @12 PS. If it puts out a consistent 14.4v (typical running car voltage), you can get away with a 33-35A version...

If you do not already have the duo, you could get seperate chargers and then use seperate, but smaller, PS units. Don't know how the final cost will shake out...

Ok so it looks like I'm gonna be a bit over budget, ahwell. I did compare various combinations and they always came out more money.

Tower has the Integy 36amp, but it's 2 x 18a outputs, I assume it's ok to bridge the outputs on that?

I wouldn't assume that. Typically in switching supplies, the total current available is somewhat less than simply adding them together, but more than just one. This is due to how the feedback circuit works. But this may be different. I would contact Integy before purchasing to be sure - or download the manual and see what it says.

Why not just use a 450w power supply from a computer they are dirt cheap with fairly clean power I see them on the side on the road all the time, old paper weights.

450w is for all the voltage rails, so only about 1/2-2/3 of that power is for the 12v line. Plus, the output is right at 12v, so any heavy load and it drops to 11.x volts, especially on the cheaper ones, and most chargers error out at or around 11v.

Ok turns out I'm blind....the Integy 36 amp PS has 3 outputs. 2 x 18a and 1 36a. Looks like a decent deal, same price as 2 of the Ofna 18 ampers.

Just got my competition electronics ps today...charged two 5S 5000mah packs with my Duo wonderfully.:yipi:

Yeah that ^

;)

Invest in a rivergate Bulldog 30 or 45 amp spend the money now. you can get them fairly cheap on tower with the coupon codes. These things are brutes. i also use them to charge my marine trolling motors. they are very well made.

I have the 45 and use it to charge my 2 Hyperion 5s 5000's @2c. with a duo charger

FYI: Most of those specialized PS units have a little adjustment pot inside you can tweak the voltage up to around 14.5 (I usually set to 14.8v because most chargers accept up to 15v). This will help reduce the current needed by a little...

How did I miss that one on Tower..... the Rivergate 45 has my name on it. I will spend $20 more just to not have an Integy.

Thanks for that find!

Redshift, cool you wont regret it. I have learned a lot here, most of all not to skimp on electronics lol. The river gates have a little jumper on them to go from 13.8 to 14.2 I just leave mine at 14.2

I use that 36a "integy" one, Its not really an integy, its from http://www.eaglemodel.com/ the directions are in chinese and it doesnt even say integy anywhere, they must have just bought some distribution rights or something. You can use it 18a x 2 or 36a but not both. Its held up well and has a cool blue light lol. It is chinese junk, but works great with my duo. That rivergate looks more heavy duty but never tried it.

Well I have to bite my tongue....... I got the Rivergate 45, and ended up returning it. Too industrial. (never thought I'd say that!)

And I figured out I'll only be charging at 8 amps per port, so it was way overkill. I instead got a 30 amp "Power Force" from HobbyLobby for $80, don't have it yet but I'll report back on that.

As for the Duo, my only major complaint so far is the weakass chime. Not a huge deal, but I was used to using a friend's PolyCharge 4 which had a chime that could be heard about 2 city blocks away over traffic noise....

AND please I need a little help with charge rate settings, I bought the adapters for charging my DX3.0 and my receiver cells, all are 2000 mAH NimH, what would be a good amp setting for those?

1 amp enough for a semi-quick charge? I have the trickle setting at 50mA, the lowest- sound OK?

what do you mean by too industrial?...was it too heavy?

Azjc I was impressed with it, no doubt, but this was a very unusual occasion for me to decide to return it. The weight was not so much an issue as the physical size. Other things that made it not work for me were.. 1. the 120V input and the 13.8 output are on the same end, and it has a short (2 foot) cord, would have made it difficult to arrange with the charger the way I want. 2. no bullet connectors, has large screw lug-type conns with SQUARE HEAD drive setscrew for some wacky reason, the Duo has bullets for input, and I don't really want to cut them off. 3. no power switch- again not a huge problem, but all these little issues combined made me change my mind.

Let me say I was impressed with the build quality and it looks like a very robust PS, but the galvanized case was large and the mount 'feet' are useless to me, this looks like something you'd have a dedicated, permanent use/ mount for, so I decided for a little more than 1/3 what I paid for it, I'd try the HobbyLobby 30 amp and my only concern with that one is it may only have a 12V or slightly higher output, but we'll see.....

Oh, and I originally spotted the PowerForce 30 amp on MaxAmps when I was buying my balance tap adapters- they wanted $109 for it- a full $30 more than I found it at HobbyLobby. highway robbery, didn't feel to good about buying even the balance adapters from MA.... anyway HobbyLobby has a 40 amp version for $100 if anyone is interested. www.hobby-lobby.com/powersupply.htm

when I was looking for a PS the size and connectors were a issue for me, it was plug and play for my 0610i and Ofna PS

How would this go? It's a Manson, and only AUD$239 (which is what - USD$170-odd) but it's 40amp and adjustable voltage up to 15v...

Hope it'll work well, cause i have ordered it - i plan to use it to sync-charge 2x 6S 6000mah lipos (@ 1C) on the DUOII that i have on the way... I couldn't figure out the calculations brianG put up, so just went overkill as best as i could - i've come to the conclusion that maths and numbers are never gonna be my forte -lol-

*edit - there is nothing that mentions the watt rating of this p/s tho... is there a way to figure that out, or does it just depend on how it has been made? The manual recommends a BK Elctronics 15v/40A/600W p/s (#1692) but it appears to look exactly the same.... likely not to be looking at the price, but could it actually be the same thing? Maybe just with a lesser W rating (considering it isnt mentioned on the "Manson" site...)

IMO its overkill for what you need, you can spend $100 @ Hobbylobby and get a 40 amp PS and you will probubly never come close to really needing that much power

thanks man =)

My only gripe with that, is that being in Australia, in need it to be 240V input with a 3 pin plug for the wall...
The 240V requirement is what pushes the price up (from what i had found while searching for a p/s) unfortunately...

I would also like to have comfort in the fact i will have the ability to charge large packs at higher rates also in the future if i ever need, hence the main reason for looking at 40amp supplies =)

Buy a little step-down transformer. They're cheap.

They do sell large project enclosures....you could have mounted it inside a project box and installed your own connectors, switch, longer cords etc. Then you coulda mounted the Duo on top...woulda made a cool charging station.

Like a bull at a gate i am - i really need to start looking into that thing they call 'patience' and the line that goes 'look before you leap' -lol-
