    All i have to say is hkj's review is spot on. I been going over his review as a recap and as a guide to make sure i did not miss anything or to get a better clear understanding in case i run into any issues. Thanks for a well done review.

    However to answer your questions:

    1) You still haven't mentioned what your criteria for a charger are. The BC1000 will still charge and discharge your batteries just fine. But as detailed in the review to which you keep replying, the MC3000 is extremely flexible and tweakable. Are you ever going to want to tweak things to that level is what YOU must ask YOURSELF. We can't help you with that. I would suggest before even posting again you read HKJ's reviews of both chargers. And some other chargers too. He is considered "the authoritity" when it comes to reviews. Then you can decide what things are important to you in a charger and then you can make your own mind about what charger you want to own. Asking us to decide for you isn't the way to go.

    2) This charger was only released ~2 months ago. They have only just received FCC certification. Maybe that's why it's not on Amazon yet. Why this is a deciding factor for you I can't fathom. Again, HKJ's review makes it clear this an excellent charger. It doesn't get any less excellent because you can't buy it from Amazon.

    The charger you want to own is a decision you have to make. There is more than enough information on CPF to make this decision, you just have to invest the time to do some reading then come to the decision yourself.

    Or at least start a new thread to stop cluttering this one.

    [Mods: I am happy for my post to be deleted too if you're cleaning up this thread, ta]
    Thanks for the reply. I plan on making my own decision was just looking for opinions on what y'all would do since you know more.

    It not being on Amazon does not affect my decision. I just didn't understand why it wasn't. Simple question. I'll be sure to start a new thread if I ask for more info in this form.

    Sorry for cluttering this thread. But I thought I did read a few posts comparing this charger to others too.

    Thanks.

    Now that the device got official FCC accreditation retroactively, it can from now on be sold freely to the USA without restriction. Before, the factory could sell to national vendors only and also didn't mind. Apart from that, Sky does not have a dedicated Skyrc brand distributor in the US, they like to do OEM's and ODM's for that country.

    With this product, the company does not push to make it a profitable success, knowing that it's an expensive product and a niche product. To them it's a fun side project, and to bring joy in the scene, also to get their name out as original designer, not OEM.

    In business, it's not always about making money

    The charger may become available on amazon or amazon marketplace but Sky isn't behind it, not their priority.

    @kreisl Perhaps David is giving us a hint that it will be available through his shop ProgressiveRC. That may help alleviate concerns about US warranty service, since ProgressiveRC has a stellar reputation for customer service in the RC community (which agrees with my experience, e.g. recently they quickly and painlessly replaced a defective Junsi PowerLog 6S which was under 1 year warranty). Hopefully the price will be competitive.

    Here some observation. In my own review , I would include such, of course.

    For testing purposes, I am 'lucky' to own a super poor Eneloop AAA cell, datecode Summer 2011. Very high internal resistance (~1000mΩ lol), and hardly good for any application. All my chargers have trouble charging it. In the MC3000, a charging rate of 0.50A or higher (e.g. the 0.70A default in Dummy Mode) will return a "Connection Break!"-error when the charging current ramps up to the 0.50A charge rate. Probably that's because the on-load voltage has surpassed an internal threshold (protection) at which the slot cuts the connection?

    Anyway, the error is interesting. Unexpected.
    ( i would have preferred a BAD BATTERY error message, i am listing it under k#23 )

    However, charging that poor battery with a 0.40A rate or lower will not produce that abnormal program termination. Also interesting, charging the poor cell with 0dV parameter terminated properly at that rate, sweet!

    What's the point of this very post?

    It is to inform the reader that an unexpected "Connection Break!"-error does not mean that something's wrong with the slot. Of course, people would eventually come to such a conclusion on their own, once they try to charge other batteries in the slot or experiment with the charge rate on their own.

    In summary, if a battery is really poor, not only MH-C9000 (HI6H error) and other chargers will have trouble charging it but also MC3000. Beware.

    Good point. Thanks kreisl. Welcome.

    ( Inversely, something similar could happen with super low IR very good Eneloop Pro batteries, the slot could throw a SHORT CIRCUIT error message. Falsely so. )

    I think this is a grand idea. I believe that things should be simple to operate and have clear messages, this certainly seems like a better message than connection break.

    Is that what connection break is. I was testing some seriously abused energizer cells that was in my multimeter, which give a low batt status on the meter. Thought would test how the charger reacts to bad cells. I would start the charging process, charges for a few seconds and not long after the charger will do 2 following things. The snb led would turn green or would see connection break on the lcd.. I ended just tossing the cells.

  11. #101

    Default Re: Test/Review of Charger SkyRC MC3000

    yeah, green snb led would mean that the program finished normally. a program on a bad cell can finish very fast, see MH-C9000 behavior on bad cells . termination criteria like cut-off voltage or target voltage are reached fast due to the high internal resistance which causes a high voltage step at high charge (or discharge) rates. so that's explained by that.

    the connection break is not easily explained by me, the maker would know the internals (code) and the explanation. but it is something like what i said. when the onload voltage surpasses an internal threshold, the slot breaks the connection (for 'safety reasons') and throws a Break Connection message.

    If you try to charge with a low current, you'll see that there will be no Break Connection message.

    Yeah, i tried that, even went as low as it can go. This only makes it last longer before the connection break error occurs. I am surprised how the DMM was able to function and it has lasted pretty long time too. The meter is a radioshack brand 2 AA's. so efficient that i even forgot that i had enegizers left. Very impressed by this digital multimeter.

    HKJ I wanted to take a moment to thank you for your technical review. I can only imagine the time that you spend to create reviews like this one. It has helped me to select this as my next charger.

    The more hardware faults you find in this charger the less i want to buy it.

    On another subject.

    The £(UK Pound) is lowest against the $(US Dollar) in 9 years, So now is the time to buy anything from the UK, like Crumpets or English Mustard.

    They may not be faults, but issues:

    1) Not all cells make contact when placed at the bottom of the slots.
    2) Charger cannot do a full power discharge, it often has to reduce current (Fixed in current production version).
    3) USB is unstable, this may be a hardware issue (Especially because a very good cable will mostly fix it).


    1) Is probably difficult to fix for all cell sizes/types.
    2) Is fixed and can be fixed on first generation chargers with a hardware modification, but do not really matter in most cases.
    3) Can be problematic for people that want to log.


    None of it prevents it from being a very good charger/analyzer.

    Thanks.

    I got a premium-like 1m data cable the other day and my Tomo powerbank LCD showed 1.75A transfer rate, which i found amazing for a 1m cable being a data cable! But the more often i plugged and unplugged it the rate dropped significantly (compared to 30cm charge cables), down to 0.30-0.50A. My only logical explanation for the performance drop is the degradation of the USB connectors on the "premium" cable. What a shame!, since the cable itself (=everything but the connectors) is premium, i can tell and i know it. I am in contact with the seller and the cable manufacturer.

    Now for logging data and transferring firmware with mc3k i use a new FT braided USB data cable. It has high resistance, slow transfer rate, but at least that slow rate is stable, now matter how often i repeat the plug test. Before ppl point at my cable recommendations when they brick their chargers with the cable, i better **** the **** up and don't recommend any cables on the forum haha.

    But i guess it's true .. one could mess up things (interrupted data logging, bricked chargers) with a poor quality USB cable. Especially during firmware transfer one needs to make sure that the transfer happens in a reliable stable way. Ppl should gather much experience with PCLS data logging (with their USB cable) first, before they decide to use that particular USB cable for firmware updating. And, to be on the safe side, no other USB device (like USB printer/fax/scanner/copier/etc) should be connected to the PC and or mc3k *during* the fw updating procedure.

    Last night i submitted bug reports re 1.04c fw, all of minor nature (k#33-37), and if it continues like that, 1.04 will never reach final release status lol. Maybe when we reach the end of the alphabet, 1.04z, we'll think 'ah wth **** **' and release that as final 1.04.

    Anyway, 1.04 is nice. So many little things which got corrected. AUTO fan works now as expected, finally

    It appears this is the newest and "best" charger currently out there for a consumer but I would like advice on purchasing a charger if possible. I Have about 50AA eneloops that I typically charge in a maha c808m and have no problems with it. I let the charger do its thing and am happy with it. I purchased that charger because it was easy to use, and was a high quality charger that I could walk away from and not worry that something may catch fire. I now have about 100 18650 batteries that have been pulled from various laptop packs and I would like to go through. I intend to use them in a few flashlights and give them to friends for their lights or vape gizmos. Even on the most simple, press the button and forget it, charge mode of the MC3000, is it the best charger out there for the needs of charging and checking 100 18650 batteries? The cost is not an issue, I simply want a proper charge from a safe charger. (I own an Ultrafire WF-139, and would classify that as not the right charger for my needs). That being said, there is mention in this thread that possibly two Xtar VP2 chargers might be a good option if you need 4 bays of charging. Any insight would be much appreciated. I am also willing to provide any additional information that may be needed in helping to make a decision. Thank you.

    Edit: While I prefer not to have to dive deep into making my own programs for every battery, I am capable of doing so with instruction, as I am not a "battery guy," but semi technically inclined.

    For just charging this charger may be a bit too much, a couple of Xtar chargers would probably be a better solution.
    But for checking batteries it is very good. Just make a "test 18650" program and assign it to all slots, then it is just putting four batteries in the charger, press the button, wait, read the result.

    Thank you for all the time you take to review chargers and batteries and everything on your site. Do you have a link to a test program for 18650 batteries using this charger, or how you would create one based on knowing that the cells I have are unprotected cells pulled from old laptop packs? Would you put an over discharged cell into the MC3000 and let it determine whether it should charge it or not, or would you test it with a voltage tester first? -As now we are digressing from the review, where should I post these questions to get answers. Thank you.

    I like to cycle the cell a couple of times, i.e.:
    Capacity: a bit more than the cell is supposed to have, for known good cells it can be off
    mode: Cycle
    C current: 1A
    D current: 1A
    Cycle count: 3
    Cycle mode: C>D>C
    Termination: 0.1
    D Reduce: off
    Cut voltage: 2.8
    Cut time: Off

    The 3 final values will be close.

    Put the battery in and read the volt on the MC3000, if it is below 2 volt it goes to recycle bin (i.e. I will not try to charge it).

    I don't think it's THAT expensive though, for what it is.
    A dedicated XTAR charger that just does Lion is what, half the price of this?

    This not only does charging, it discharges/analyses, you can tweak every setting perfectly, set high charge currents for faster charging, plus it charges AAA/AA's, NiZN. It's firmware upgradable so it's future proof (as long as the new battery fits into the slot)

    You're getting 5 times the functionality for 2 times the price.

    Makes perfect sense I think.
