Test/Review of Charger SkyRC MC3000

Depends, customs do not catch everything!

hkequipment.net still sells for the promotion price of 95.95 …
can order now - but it will be shipped mid jan

I had to order the UK version because US and EU were both out of stock and relisted as pre-sale. Since I have a dedicated 13.8v power supply for all my chargers I won’t be using the included adapter.

I also ordered 2 small fans 4.2cm wide to install the on the back of the charger, pointing to the heatsink. I hope the stock output is 5V and provides enough current to power 2 additional fans. If not I will wire them to the USB output and use a mini relay if necessary. I suspect the heat generated with 1A discharge across all 4 bays will deteriorate the components inside the charger.

USB powered fans sound good… :beer:

The charger is quite good but the price is killing me :smiley:
unstable bluetooth is a let down

Bluetooth is not unstable, but the phone program do not work. Hopefully they will fix the phone program and everybody will be happy

I see
But if it can connected to smart phone can all control from the charger switched to the phone?
Or it can only monitoring the charger?

It can control, it looks like you can define "charge" programs on the phone and execute them on the charger.

We are all very lucky someone with your knowledge and expertise will take the time to do so complete a review.
Thanks :exmark:

No surprise to see they falsify CE and UL and FCC labeling.

Sad though.

Just received this charger today, this thing is actually much larger than it looks, see how the tiny the opus is besides it.

I’ve been playing a bit in “Simple” mode and so far it performs as expected. I have set my first mode to charge 4.2v cells at 1.5A with termination current of 10%, this is for all my 3,000-3,500mAh batteries. The Simple UI only takes a couple minutes to learn how to use even without the use of the manual. I’ll use it some more in this mode before jumping into advanced.

But one thing I can’t do is to select the same program for all 4 slots at the same time? Right now I have to select each slot individually and the program for it. (I don’t want to mix different cells in the same charger).

In a program move down to "Save to", press "Enter" and "Arrow up", then hold enter down.

Thanks! that did the trick. :slight_smile:

I also find it interesting that this charger will limit the current to 0.15A for all fully discharged cells until they hit 3.2V undear load, some kind of a “soft charge”, I guess this is to prolong the battery life. For healthy cell this did not take long, from 3.05V to 3.20V only 30mAh were induced to my Sanyo GAs.

I hope in a future FW upgrade the program can be selected for all slot together when all 4 are flashing with either arrow, because with the current 1.2 FW these buttons do nothing.

The Bluetooth function worked fine for me, I find it amusing that it doesn’t require searching and connecting the device to your phone, just turn on bluetooth, open the app and it will connect automatically.

Thanks for the detailed review HKJ. I hope to study the whole review soon.

It took me a while to figure out that “RAM cells” must refer to rechargeable alkaline batteries. Is SkyRC or anyone else selling a RAM cell which would be interesting to us?

In regards to being able to “hide” chemistries: I agree, by itself this feature isn’t very useful. I think that I would like to see something similar though, or maybe it’s already present. I’ll examine your review in detail soon, but what I’d like to see is a way to lock down the charger to a specific charge profile . I’d expect that the PC interface could be used to create the profile and lock down the charger. This would be good for those who like to sell a few custom flashlights as turn-key solutions and not worry when we fall asleep: “Will my customer burn their house down tonight?”.

Several years ago my boss got a medical device destroyed by leaking RAM cells to furnish an opinion.

Kids, don’t use them @home. They might occasionally destroy unattended flashlights.

I’ve never heard great things about Rechargeable Alkaline. I have experience using them in graphing calculators… they nothing special. What I used back then was certainly well eclipsed by LSD NiMH. If things change I’d like to know about it though…

MC3000 Firmware V1.02, Hardware V1.04:
App V2.5 is working here, since i have altered the language setting of my Samsung Galaxy S5 (Android 5.0) from German to English (UK) !
With german language settings fixed point values (e.g. 4.20V) are displayed as “fixed colon values” (e.g. 4,20V) in the app. And the app will crash saving such a setup.

I’ll have to test if the app is still “congesting” after some hours. With german language settings i had to stop app, remove app in android task manager, clear cache in android settings, (cycle charger power off/on), restart app …

At least they are making improvements. Another case of user debugging.

Whats the right voltage setting for charging nimh? The stock setting is 1.65V and I think it’s a bit too high, I set them to 1.55V instead and got ~2450mAh capacity from a pair of eneloop XX. Haven’t touched any of the other settings as I’m not very familiar with ni-mh chemistry. I’ve been using a maha 9000 in auto setting for the last 5 years and it seems to be doing ok.

There is no right voltage for NiMH when using -dv/dt termination, but it must be high enough to not interfere with the -dv/dt.
