SkyRC — IFA 2014 — MC3000 charger-analyzer

[Gauss163]

Well I'll certainly be happier if it costs closer to $50 than $133. Let's hope for some more concrete information soon.

 

[braddy]

As confirmed by Sky office the Gearbest page is a 'fake listing' in every respect. Stolen outdated photo (from Google Images, IFA 2014), wrong edited specs, wrong pic, wrong info, and most of all wrong price. Sky never quoted any price to anyone because it is still unknown.


Safely ignore.

Nice try Gearbest

If you checked with the manufacturer, then you must be correct in your statement. ""the number (price) is a total fantasy number. based on thin air.""

If you checked with the manufacturer

i did:

As confirmed by Sky office

 

[Gauss163]

If you checked the manufacturer...

Kreisl has confirmed above that the only thing he knows about the price is "that it will cost more than 50US$". That implies nothing whatsoever about whether or not GB will honor the price that they quoted (or how that price may compare to others).

 

[braddy]

He has told us what the manufacturer has said about the Gearbest page and price, the manufacturer makes it clear that Gearbest is making it up.

 

[kreisl]

Yet another Chinese vendor with the same stunt: Banggood :fail:
Looks like a copy paste of the Gearbest page. Both vendors have been notified to take down the bogus page (totally made up page with wrong info, wrong specs, outdated st*len photos/pics, bogus price).

(...)

I heard user manual has grown in size now totalling 41 numbered pages aha yes sir

 

[Ferdinando]

41 pages !!
wow !!

... thus the charger is able to accept a whole variety of PSU adapters from your household (12V, 15V, 18V, whatever you got!)

Frequently users have spare high-quality 19V PSU's left over from old laptops. Will it work with them?

It is not clear why 18V (vs 19V) is often specified as an upper limit. Perhaps that is the upper limit of some commonly used component(s)?

 

[Gauss163]

With MC3000 it is now possible to 'produce' LiIon cells with any stable voltage between 2.50-4.25V with 1 or 2 program steps.

Is this really true? To discharge to a stable voltage you would need a CV phase during discharge also. Does the MC3000 have that?

Can the MC3000 be programmed to maintain a cell at any voltage, with user-settable recharge threshold? For example, this would allow the user to simulate the laptop battery-saver feature, e.g. charging and keeping cells at 4.0V in "standy mode".

Ideally a dreamcharger should have a way to (dis)charge to any (safe) user-specified voltage, with user-controllable CV and maintenance phases.

Yes, it has. The option is called D.REDUCE.

If your aim is "charging and keeping cells at 4.0V" you could play with the RESTART VOLT option. The minimum voltage difference between TARGET VOLT and RESTART VOLT is 0.02V, for example 4.00/3.98V, please check my post #300. For LiIon, the TRICKLE C. option is fixed OFF. For NiMH, TRICKLE C. and RESTART VOLT are mutually exclusive: only one the two options can be active.

Information why 18V is the upper limit in the spec is not available. 19V PSU adapters won't work, the screen will give you an input overvoltage warning and the charger refuse to operate properly.

I'm slightly confused. I thought the MC3000 package would include a power supply. Has this changed?

 

[Curetia]

I hope that they will include a power supply, because I don't have one for a charger.

Kreisl, do you happen to know if SkyRC will ship production units directly to reviewers like HKJ at the same time as they ship to the dealers?

In common with many people here on CPF, I wouldn't be buying one until I'd seen a good review from someone like HKJ, so it would be a good thing for the retail packaged production units to land in the reviewers' queues as soon as possible.

 

[kreisl]

I am only aware of SkyRC shipping desktop copy to me and to Third-Party software developer for PC Link software alternative.

Others could ask their preferred vendor (BG, GB, FT, or a local national dealer) for a sponsored sample i guess. Actually it is rather common practice these days that those vendors contact an active forum user or customer and even ask for a review, see for example reviews on budgetlightforum.com .

Anyway.

I am gonna be the first to forum review it :huh:

 

[braddy]

To not send one to HJK would imply a lack of confidence in their charger.


You should instruct them to get one to him as quickly as possible.

 

[kreisl]

oic

 

[braddy]

I have no idea what that means, what does it mean?

Oh, I See, perhaps?
