Thread: SkyRC — IFA 2014 — MC3000 charger-analyzer

  1. #1

    Popcorn SkyRC — IFA 2014 / CES 2016 — MC3000 charger-analyzer

    IFA 2014, one of the world's relevant trade fairs for consumer electronics and home appliances, did not only unveil Galaxy Note 4 but also premiered a demo of a new advanced charger for us flashlight, ecig, RC toys, camera, charger, electric tools and appliances fans. It is rather big and heavy with its integrated metal heat sink and smart cooling fan, supports multi-chemistry, 73mm long cells, up to 2×26650+2×32650 out of the box, 3.00A for a total of "12 amps" charge rate so to speak, also applicable to 12×AA or 16×AAA NiMH parallel charging via holders, and with its pixelated LCD screen and eight buttons shares UI features of a Turnigy or iCharger (just without their balance charging functionality, of course).

    if you will - it basically compares to a (non-balancing) hobby charger with 4 independent channels in an integrated battery tray, the good looks of a Maha, and the build quality of a premium. I got some preliminary specs at hand but much is still in the works. And who knows .. i might turn this thread into a review/test thread when the product becomes available, a final test version or so. Ever since the Maha C9000 was released to market in 2006, i've been dreaming of such a multi-chemistry machine. The Maha was very good, build quality, accuracy, but it lacked LiIon support. A first type of "dreamcharger" on the market was the Intellichage battery charger and it went into the right direction but this one, designed and manufactured by SkyRC, goes imho further: sort of a 2nd gen dreamcharger, i am dubbing it "DC2" for now, to be released in 2015

    You want?

    Since the charger maker may listen to our discussion while continuing with the development , please everybody share your thoughts whether you'd like the idea of a hobby charger with integrated battery tray and what kind of specs and features it should have; at least this new type of round battery charger sounds intriguing, doesn't it?

    Q. Hey squirrel you nuts is this another vaporware thread?
    A. No Johnny dis ain't another i-want-a-dreamcharger thread, **** just got real!

    Q. Btw haven't seen you much around lately. So that's what you've been up to in the recent past?
    A. You could say so. I still use my flashlights everyday, i just lost interest in new lights, that's all. The DC2 project has become my new motor in the scene. Genuine joy.

    Q. Good for you. The device looks like an expensive overkill but i'd still be interested in learning more about it. Can you provide info, news, or updates on the development?
    A. Sure i can, thanks for your interest. Stay tuned, i'll keep you posted. Overkill?, maybe. But also much fun. And things keep getting better, you'll see….

    Very interesting. I remember reading about this some time ago, and held off buying the Opus. I'm glad I did, as the Opus has needed a few releases to deliver the goods.

    I assume the RC crowd and the fast growing vaper industry will be the biggest market, but I'll be interested to see the final specs for this.

    No idea on price yet?

    I'll grab some specs for ya, no problem. Just lemme know what kind of detail you'd be interested in.
    Price? No exact idea. Prolly more than MH-C9000 price, obviously. Because it does more than the Maha

    For our reference there are 5 extensive MH-C9000 threads (last updated 2017-10-20):


    For the MC3000, several youtube and discussion threads on forums exist. The following lists some written reviews or similar contributions on the net (last updated 2016-05-27):

    Nice.

    The below comprises a redacted filtered list of reasonable realistic feasible likable serious strong or urgent suggestions, nothing too distant from the present state of things. On another note, if you experience "trouble with something", we need to discern whom/what to really blame. For example in 'my PC is dirty and freezes when working with DEX!' or 'my *****y batteries don't get charged properly i hate the charger for it!' or 'my Mcafee antivirus automatically deletes the PCLS *.EXE this needs to be fixed!' or 'my flat is located in the Sahara and i get over-temperature error message 3x per week!' or 'i don't like the charger because it doesn't fit into my favorite pink desk drawer!' … whose problems are these tbh yours or Sky's?

    The below list, items k#1…k#62 regarding firmware v1.03, was covered by the current firmware version which is v1.11 (June 2016), the changes from v1.03 to v1.11 are the following:

    CONFIRMED = the forum-reported bug/issue/suggestion/idea has been confirmed by me, it means that i was able to reproduce it on my test sample, it is something real
    UNCONFIRMED = i was not able to reproduce or understand the forum-reported bug/issue/suggestion/idea, maybe it's not real
    FIXED = the confirmed bug/issue has been fixed in the firmware v1.11, says the maker
    BEING FIXED = the confirmed bug/issue will be fixed for the v1.11 release, says the squirrel
    DONE = the confirmed suggestion/idea has been implemented in the firmware v1.11
    PENDING = not submitted. not tackled yet, topic will be looked at in future
    FOR FUTURE RELEASE = submitted. not tackled yet, topic will be looked at in future
    NOT AGREED = submitted. no agreement achieved, topic needs to be revisited in future
    TESTED = the fixed bug/issue in v1.11 has been tested OK by me ('bug is gone!')
    NOT TESTED = i have not tested the allegedly fixed item yet sollie hh

    List of PCLS (PC Link Software) suggestions for improvement, or bugs (in arbitrary order):
    - see Tim's thoughtful list (UNCONFIRMED)
    - Win10 support (NOT AGREED)
    - not a bug: PCLS window is too big for 720p screen resolution (UNCONFIRMED)
    - not a bug: PCLS should disable Windows OS sleep/standby mode otherwise logging gets interrupted (UNCONFIRMED)
    - bug: CSV log appears to be 3-10sec shorter than LCD logging (CONFIRMED, FIXED, TESTED)
    - bug: displays NiMH load voltage during RESTART charge routine (CONFIRMED, FIXED, TESTED)
    - bug: Refresh mode does not have fixed Cycle Count. it should be fixed to N=1 (UNCONFIRMED)
    - bug: CUT TIME parameter range too restricted compared to SPV (TESTING)
    - idea: save the 30 programs to computer file, and also reload them by overwriting altogether (DONE IN DEX)
    - idea: save User Calibration data to computer file, and also restore them by overwriting present calibration data (UNCONFIRMED)
    - idea: should save data to file all the time, instead of just at the end (UNCONFIRMED)
    - idea: separate independent Start/Stop buttons for each of the 4 slots (UNCONFIRMED)
    - idea: a 'Clear Graph'-button for each slot (NOT AGREED)
    Note: PCLS has demo and ref character and also serves to inspire independent third-party software developers to build their own PC software. In terms of likability, utility, stability, flexibility, compatibility, functionality, etc PCLS has already been surpassed by free open-source software such as DEX, see below. With the existence and regular updates of DEX, which is obviously a very serious piece of MC3000-compatible PC software, there is imho little point left in using PCLS anymore. If you use and like PCLS, do consider switching to DEX anyway. PCLS has gone obsolete kinda. Btw no external driver needs to be installed, once you connect the charger with the Windows PC (e.g. WinXP SP3 or Win7 with .NET Framework 4.0) the necessary driver is installed internally/automatically and it is recognized as USB-HID in the device manager.

    without adapters: 4xRCR123, 4x10440, 4x14500, 4x18650, 4x26650, or 2x32650+2x26650, and all NiMH sizes: 4xAAA, 4xAA, 4xC, or 2xC+2xD. as mentioned, the device is rather big compared to the tiny XTAR XP4/XP4c

    lowest possible user-set charge rate be 0.05A, lowest possible user-set discharge rate -0.05A. Of course, during the CV-phase of LiIon charging/discharging the rates can get much lower (0.01A, 0.001A, 0.0001A) depending on other user-set parameters such as termination current.

    for comparison purposes, iCharger lowest user-set rates are 0.05A/-0.05A, same thing!

    Thanks for the info,Kreisl! What's the maximum charge rate when charging 4x18650? Can one charge them at 4×3.00A?

    lol man, that's exactly what the OP stated

    each slot is controlled individually, you can set each to 3.00A charge rate, that's the maximum possible for LiIon charging. with 4 batteries and each at 3 amps at the same time simultaneously, the total is 12 amps, yep - no problem with this machine

    the preliminary specs seem to limit NiMH charging to 2.00A (per battery). of course you can mix batteries, e.g. M1=Eneloop 2.00A, M2=NCR18650B 3.00A, M3=26650 3.00A, M4=Eneloop 2.00A, for a total of 10 amps.

    you'll need some good external power supply for such heavy load charging. because of size and potential thermals, an AC/DC PSU (power switching unit/power supply unit) is not integrated in the machine and the user must connect the charger to a 12-18V DC source. any simple power adapter would do the trick, e.g. with 60Watts OUTPUT DC 15V 4A. i don't know if such a power adapter is included in the retail shipping unit of the product and maybe this question has not been decided upon yet. please note that Turnigy, iCharger, etc don't come packaged with a FREE PSU adapter. i, for example, run my iCharger 106B+ with the old version(!) power adapter (MODEL:KYT1200300AV) of my Opus BT-C3100 v1.0 charger.

    OK, a few more questions.

    Can this new charger measure cell resistance?

    Will I be able to use it for data logging easily? Not that I do this at the moment, but if I'm going to invest in one of these beasts, that would seem to be something worth doing.

    Finally, how future proof is this charger? Will the firmware be easily updated?

    Thanks again for bringing this charger to our attention. Oh, and what date is the IFA?

    Yes, it can measure IR on each cradle.
    Yes, it gives out charge and the more important discharge capacities, but no usb out for data logging to a pc.
    Future-proof? These days, it's either you stay with the times or sleep behind. The firmware is not upgrade-able digitally by the end-user.
    Now available at gearbest.

    Edit: I assume the OP means the current and the latest v2.1.

    tatasal dear friend, i think i am in the wrong thread

    Dubois you have some clever questions there! Firmwarez?, Updating?, the BT-C3100 dreamcharger doesn't have such a possibility so how come you think …

    Someone's ahead of my specs sheet


    Oh, IFA starts this Friday, Sept 5th:


    Check out Hall 28 and look for Booth #525. Xtar is in Hall 26.

    I am not into vaping, but personally I believe something that can measure the discharge capacities of cells, specially to vapers, is a very good feature to have. It eliminates the guesswork about the health of your cells, a compared to just a straight-up charger.

    currently the implemented chemistries are:
    • NiMH
    • Eneloop
    • NiCd
    • NiZn
    • LiIon
    • LiIo4.35
    • LiFe

    simply because these are chemistries for which round/cylindrical batteries do exist and may still be found in old stores, shops or homes. when you go shopping for recent production stock, you'll have a hard time to even find round NiZn, NiCd or LiFe batteries. cylindrical LiPo or cylindrical Pb batteries practically don't exist or are extinct, that's the main reason why these 2 chemistries are not implemented at this point of time.

    however, implementing new future battery chemistry technologies is a piece of cake, since it is all a matter of expanding the firmware only. And yes, it will be possible to update/upgrade the firmware FOR FREE . Rather easily.

    I know that iCharger supports Pb and LiPo, non-cylindrical batteries. But it doesn't have dedicated modes for Eneloop nor LiIo4.35

    This is a very different beast from the Opus, and looks better from what I've seen so far.

    I bet the vaper crowd would look at this and say "a bit overkill for those silly flashlight people. They don't need all that functionality".

    i checked. Yes, the charger measures cell resistance on the fly, that is when running a MODE, and the LCD screen displays the miliOhms-value when you switch to the SOV (slot operation view). SOV shows quite some details about the slot/battery, not only voltage, cell internal resistance and elapsed time, lol

    ok, so basiccaly will be made by the same company what created the opus c3100. but the new version will be much more premium quality( and at higher cost) and with 3a charging current.
    however for normal people also 1A or 2A(wuth 1 and 4 slot) of actual opus would be ok....... so basically this new version will be only for "PREMIUM" people........

    For what I undertand in this thread the upcoming device has nothing to do with the OPUS company. I have my own idea about it, but I'll wait to see if the folks visiting berlin IFA confirms my suspicions.

    Hello Dubois,

    No...

    But you may have a "premium" tool to measure the performance of your batteries with.

    Lol, fair point. The only "premium" label I normally see is on a beer bottle. Even then, I rarely trust it. I might drink it .....

    Getting back on topic, I am looking forward to see some real world impressions of this charger.

    1. External user supplied power supply required
    2. Charge Rate: 100mA - 3A (Lithium) (2A NiMH) (subject to powersupply) *****
    3. Advanced Info display includes Cell internal resistance *****
    4. Will charge LiIon @ 4.35V (some adjustment possible on actual cutoff level) *****
    5. User Upgradeable Firmware *****1/2
    6. Supported Chemistries: NiMH, Eneloop, NiCd, NiZn, LiIon, LiIo4.35, LiFe
    7. 4 Independent Battery Bays

    Hmmm... looks pretty good... why did you list Eneloop as a separate Chemistry from NiMH? Is the charge program any different for these LSD cells?
