SkyRC MC3000 Charger. Post your thoughts. Better than average?

ARsee, using my iCharger (pretty much the same UI as the SkyRC’s B6 and the others) was truly simple and straightforward to use, that’s why I decided on getting the MC3000, on the assumption that it’s just like a hobby charger but with four channels and bays. Oh boy, how wrong I was.

I know you got a defective C4-12, and a replacement is on its way, but if you like its UI, then you’ll be amazed how simple can a charger be designed like the C4-12, literally a “just put the cell in and off it goes” UI.

You can’t have that in the MC3000.

I have not given up on the C4-12 just yet. I’m doing a little research. There are many many threads regarding chargers. The problem is (for the most) the info is dated. I’m sure if I took the time to read, some of them I would find the answers I seek. The problem with that is, the forum search function pulls up 10+ pages of them! I wonder if there’s any review pages like Consumer Reports? That would be nice.

Thanks for the reply, tatasal :slight_smile:

I have an order at GB for a SkyRC MC3000 after I read all the good reviews. Are you saying you can’t just put a battery in there and charge but instead have to toggle a bunch of settings? You’re already giving me buyers remorse.

Technically it’s highly rated, good graphs, etc. however,_ a good ’technical spec result’ should not be an ’end-all’ as our only basis for conclusion because, in the case of _the first generation of the MC3000, no review ever showed that, IIRC, it shuts down when discharging 4x1A because of over-heating, the fan was blowing in the wrong direction, the pins of the plastic casing that retains the slider springs broke easily, the fins of the heat sink should have been in a vertical position instead of horizontal, and numerous other bugs that continue to show up every now and then.

No need to go far, just read this link, it’s all documented in this humongous thread: SkyRC — IFA 2014 — MC3000 charger-analyzer | Candle Power Flashlight Forum

…but since you already have it coming in, let’s see how will you find using it.

Don’t get scared off of the opus. I have the 2.2 mine literally runs day and night. I bought the back up replacement fan because I was worried about it. But several months of 24/7 usage it’s going strong. Between my wife going through 4 to 8 powerbank batteries a day, me using 4 or 5 between vape and light at work. And sorting pack pulls from recycle bins. It’s charging or discharging non stop. Fan is holding up fine. In a quiet room its a little noisy. With a TV on or something it’s not bad. My ps3 is much louder then the opus fan. I plan on purchasing a second opus when opportunity allows.

I like the 1 amp discharge rate. The lii 500 only does .5

The one thing I’d want a skyrc for is the 2 amp discharge rate. But I think I maybe better off getting a real hobby charger.

But big thumbs up for the opus instead of sky rc. But it’s what your needs are. For that price could probably get a really nice hobby charger

Nice post :+1:
I’m curious since your v2.2 has been doing well. have you looked into the newer versions at all?
I would like to know what has changed since v2.2. There’s nothing listed on their website.

The v2.2 is still the latest. There are two model designations (BT-C3100/BT-C3400) v2.2 but they are basically the same, only some parameters was changed (like maximum discharge voltage, from 2.8v to 3.0v). It was requested to be changed by an Amazon dealer of Opus.

Like in my case, in my Opus I only charge sometimes 2x18650, then on the remaining bays either I charge or refresh some Eneloops…they’re a breeze to use.

Try doing that in the MC3000….

A user suggested the SKYRC MC3000 to me over the Xtar Dragon. I usually like to look up reviews before I invest money in a product. Ultimately I didn’t choose the SKYRC as it is littered with issues anywhere from firmware bugs/slider pin breakage to cheap buttons. I also read allot of people requesting what firmware/hardware versions before buying.

The SkyRC is the most flexible and precise charger on the market. To improve precision people with precise equipment can calibrate their own chargers very easy.
The first batch had one hardware issue (Sometimes a pin breaks inside). At the same time this was fixed the fan was also turned around, this improved the cooling, before that the charger had to automatic reduced the discharge rate to avoid getting too hot.
The software has been updated a couple of times, but all the basic functions works in all software versions. The newer versions has fixed some obscure details and added a lot of new stuff to the charger. Because the software is user upgradeable all owners of the charger can upgrade the charger.

Opus and Dragon is nowhere near the functionality and precision of the SkyRC charger.

Better than average is an understatement, this is the best charger there is for this hobby. Build a cell shaped contact holder with external leads and you have a powerful charger/analyzer for all sorts of batteries.

After getting the MC3000 you won’t even think about spending money on other chargers. I followed very closely the MC3000 development thread on CPF and was an early adopter, the details they took into account when making this charger is amazing.

Of course, it is now time for them to launch a V2, few things can be improved specially an easier UI and more efficient cooling system. But that’s the only complain I have after 1yr+ of use.

All things considered, I would like to have the SkyRC MC3000. I feel it would be beneficial to me in many ways. The UI /programming is a bit much though. If they update the charger to a more simple interface, I may consider purchasing at that time.

I just ordered two Opus BT-C3400 V3.1’s.
If I come to not like them, I’ll gift them to my kids (they’re vapers) for the flashlights I gave them for Christmas, and move on.

Thanks for responding to my post! :slight_smile:

The SkyRc is the most flexible and precise charger — I never disputed that, nor posted anything contrary to that, and at almost 3X the price of the Opus, it should be more precise.

On the other hand, my point is about the UI of the SkyRC —- the SkyRC is nowhere near, not even close, compared the Opus and the Dragon when it comes to UI. :beer:

The charger has 3 modes, two of which are simpler and easier to use. However, to unlock its full potential one must go with advance mode and manually program each charging settings to suit a specific group of batteries (it memorizes 30 settings). After the initial steep learning curve it gets relatively easy to use.

The opus is a good charger, but not for people who look for absolute accurate readings.

My MC3000 has been pleagued by all the hardware problems of the 1st generation but they have all been solved in later iterations.

My biggest pet peeve is the UI, i have nothing against UI that you have to practice and memorise (was a fan of the M43 UI) but this one is poor, i don’t think it has any internal consistency or relatedness to intuition, it’s just bizarre and clonky., i master it but i don’t like using it.

Exactly…I was at loss for the correct description, and you got it right….not intuitive, just bizarre.

I have an Opus BT-C3100 v2.2 already and A SKYRC MC3000 in “packed” status on GB. I’m a newbie when it comes to batteries. Should I stick with the Opus BT-3100 or use the MC3000? I have a bunch of old eneloops that have been used in my solar lights for years that I want to refresh but I also have a bunch of 18650 batteries. I read from HKJ’s review that the Opus uses pulse charging and I’m afraid that might not be good for the batteries.

Good question, too bad nobody answered it. I want to buy a new charger too but still on the fence about which one. If a simple charger can help me identify fakes by letting me know the capacity of a battery, I would be happy. I think it would be too much to ask for if a charger could check and verify protection circuits on protected batteries as well, but that would be really nice.

I’m really happy with my mc3000.
I didn’t program the charger itself, but have set al different charge and discharge settings i have on my phone.
So yust put in the battery, select what i want to do on my phone and of it goes.

I’ve had the Opus v2.2 for a few years, and has always served me well, and the fan never bothered me. However, I was always looking for a way to discharge or “store” batteries. I have close to (60) 18650, 350’s, 340’s, 26650’s & 14500’s. Was going to buy the MC3000 because of this function. Then decided to just use 2 Miboxer C4-12’s, and dedicate the Opus to discharge cells for storage. Set the switch on the bottom of the Opus to 3.7v. Discharge the cells, then charge. They stop at 3.67v which is perfect for long term storage.

I do it all the time no problem. In dummy mode the MC3000 is just as easy as the Opus which I also own but have no reason to use any more. If you are satisfied with the preloaded charging amps value then its a one button start. The Opus is beaten by the MC in every single aspect but the price. I can afford $85 so quality and features won over value and I’m very satisfied.
