Need help on the charger setup I want to buy

[R1Ryder]

I need a good charger setup since Im hooked on 700e size helis.

Here's what I'm looking at- 24v 57amp 1400w PS for only $75.00 with free shipping
For the charger I'm looking at the iCharger 308Duo

Questin is will With that power supply I be able to get 30amps for each side or is the powerlab8 better to go with that PS

and will this generator be fine to run this setup I want at the feild, 4HP OHV 4 stroke gasoline engine, 1650 Watts,2000 Watts surge, Produces 13.75 amps at 120 volts





Thanks

Everything looks good, but only expect about 25a x 2 on the charger. Probably more like 22a. But that is still plenty. Plan on about 20% drop from the genny to your charge leads. Real world I am dropping 18% with a 30' extension cord, 3x47a ps, sound amplification and a duo4010. In fact, I just measured it again today.

1600 - 320 = 1300 va. / 25v = 52amps or 26a per side, but you will be right up to the circuit breaker trip level on the genny. So 22a will be the safe region. Your genny is going to be the weak link, not the psus or charger. But certainly enough for unlimited flying on a 600, and around 4 flights per hour on a 700.

308Duo has a 60A input limit. And at the full 60A, at 24V, you can get 1300W out.

For 6S, that means 51A total output (worst case, at the full 4.2V/cell, the current will start higher when the pack voltages are lower). So you won't hit 30A+30A regardless, but you can get 25A+25A.

The PL8 is an outstanding choice. But it's a single channel, and 40A, 1000W max, for 6S. So you know you'll be getting less total output. There's the new Dual PL8, if you need almost-obscene power

For the generator, let's assume 90% efficiency for your power supplies, as well as for the charger.

1300W output from the charger / 90% efficiency pulls 1445W from the power supply.
1400W from the power supply (since that's what they can actually produce) / 90% efficiency pulls 1556W from the generator.

(using these assumed efficiency #'s, 1400W supplies could feed about 1260W to the charger)

I hope the power supplies you're talking about have Active Power Factor Correction. If they're server supplies, they almost certainly do. If they don't have APFC, the effective load on the generator will go up significantly, by maybe 25% or more. Reducing the output you could get from the PS and charger, before overloading the generator.

What kind of generator are you looking at? An inverter is nice, if possible. Less weight, less noise, and less fuel consumption. Plus clean output power.

I am very happy with my 4010 Duo and two deep cycles (also have a 24v47A PSU for home).

And you will notice sometimes I use 3 deep cycles for 36v for max output and for funflys.. you cannot do that with the 308 Duo.

this is the power supply http://www.ebay.com/itm/24v-57-Amp-D...item3cd4d121f4

now im looking at this bigger generator http://www.ebay.com/itm/Quiet-Genera...61268513268%26

heres the other gen I was intrested in http://www.ebay.com/itm/Portable-200...item4ab30c133f

Im looking to charge 2 6s 5000mah packs in atleast 20 mins max , so if theirs another charger I should check out let me know

I really like this charger from progressiverc http://www.progressiverc.com/the-dou...00w-combo.html would I be able to get 20.0A off each charger with the 2500w generator

Thanks

Thats cool no gen needed , so how many 6s 5000 packs can I charge off of 2 deep cycle batterys

what PSU are you using for home

[Slyster]

I fly a Goblin 500 and Goblin 700 both of which 6s5000 packs (2 of course for the 700). I can charge probably 13-14 packs... so depending on how many flights I want, I decide how many flights I put on each heli. It works out well for me, as my perfect number of flights on a typical day is 8 (typically 4 on each heli). Sometimes I pre-charge my two stick packs and 2 single packs in advance for a longer day.

The deep cycles cost $85 each. I use the feathermerchantrc PSU ($110)

Deep cycle looks like the way to go


Thanks

[R1Ryder]

Sticking to the plan on using a generator, so will the charger adjust it self to how many amps it can charge a Lipo off each port when running it off of the generator
Or do I have to set the amps
Thanks

For the 308Duo (or most chargers) you can configure a max amps it's allowed to draw from the source. To avoid overloading your supplies/batteries/generator.

As far as generator choices, personally, I'm more comfortable sticking to brands with more-established history & support. I'm not sure I'd include the ETQ in that list (though at least it's an inverter). I definitely wouldn't include the red one in that list.

The Champion 2000W inverters are used by a lot of folks for RC use. They're almost as quiet at the Hondas, still very fuel efficient and light (~50lbs), and have a good reputation for reliability. And while they haven't been on the market as long as the Hondas, I'd feel better about the Champion than the others you mentioned, personally. New, they're somewhere around $550. You can buy refurbished ones on eBay for $400:

I was fortunate enough to find a good deal on a used Honda EU2000i, but I had to watch Craigslist for a while. If you could find a used Honda or Yamaha in that sort of price range, I'd suggest one of those, but I wouldn't have significant reservations about the Champion (I was going to go Champion if I couldn't find a used Honda/Yamaha).

The 2000W inverters are all 1600W continuous. So, see the same charger output numbers I'd listed in post #3.

Oh- with the Progressive 700W combo you listed, no, at 6S, you will never get above ~12A output on those chargers. They're 20A/300W. And at 6S (25.2V), 300W is 11.9A. So you could get 12A + 12A.

Ok Champion it is..
So what charger would you recommend the Hyperion duo 3? Looking for something easy to run that charges 2 6s lipos at 30 mins max

for sure a duo charger (IMO) that leaves the 308, 4010, and a few others.

[Diviner]

Icharger 308, 4010 or the pl8.

Avoid the hyperion. I had 4 of them.

A Champion and 308 is a very prudent choice. Your link to that power supply setup is a great value. Your might be leaving 200w or so on the genny. If you go the 4010 route (overkill) you might just want to request a third psu unit. But I have stress tested my psus, and I can pull 20% over their rated value. Not ideal, but it can be done for a short time.

So for around $650, a value conscious buyer can get a full genny field charging setup.

$400 refurb Champion
$30 psus do it yourself
$230 308 at 15% off

Its really remarkable how affordable high powered field charging has become in just a few years. Three years ago that setup was double.

[RedOctobyr]

Diviner, where do you get 15% off a 308Duo? That's intriguing.

R1Ryder, another vote for 308Duo, 4010Duo, or PL6/PL8.

To charge a pair of 6S 5000 packs in 20 minutes needs 2C to 3C, depending on how far you're running them down (3C for my packs is about 13-14 minutes, though I tend to use about 55-60%).

3C would be 30A. Any of the 4 chargers I listed could give you that.

The PL6 can give you about 32-36A for 6S, running on 24V. The PL8 can do a full 40A. The 308Duo can do 50A total, or 25A+25A on each channel, if running flat-out doing 6S. Or 30A on one side, 20A on the other. The 4010Duo can do even more (maybe 70A total?).

The PowerLabs are outstanding chargers, with great support, and a proven track record.

The 308/4010Duo chargers are newer to the market, the 4010Duo came out around January, I think, and the 308Duo has been on the market for around a month. They have had some reliability issues, some being firmware-related. The manufacturer has been working on the firmware stuff. If you buy from a good vendor, like ProgressiveRC.com or buddyrc.com, you know they will help support you with any issues. The flexibility of the Duos is really appealing for me, 2 channels gives you a lot more options, and you can fly continuously with fewer packs.

I bought my 4010 from Mike.

[R1Ryder]

That's what I want fly more with less packs

Thanks for the info on the discount

[R1Ryder]

So I'm set on the Champion Genny and PSU, now doing research to see if I should go PL8 or 308, I like the screen on the 308 its more high tech
