    I couldn't get any results for any keywords at all. Thank you for taking the time to find it for me. (Now the charger says low input voltage when connected to my computer. I will need to figure that one out or just use another computer)

    Thanks again

    After some weeks of using, there΄s one annoyance left for me:
    The fixed contacts of the slots are not far enough out of the case. When using flat-top 18650, there is no contact made, unless i am putting in the batteries at the upper limit of the spring-contacts. So no more temp-control..
    I don΄t think, that this is due to compatibility issues, I have most problems in slot number 2, where the fixed contact is completely in-line with the case.

    Yeah, that would be possible, but I don΄t like to work ON the charger, but WITH it
    Besides there would be a simple solution and just get the contact 2mm out of the case..
    And no problems with resistance when using magnets?

    You just have to wait for a future version if the contact solution is simple. The magnets is the simple solution I use

    Same resistance reading. I just tried with a button top cell with and without magnet.

    Question Re: SkyRC — IFA 2014 — MC3000 charger-analyzer

    The SkyRC MC3000 webpage has just been updated.
    The firmware update has been removed (?) and in it's place is a file called MC3000.apk which I assume is the MC3000 app for an Android phone.

    Quite bizzare.

    I never received a response from Progressive RC, but it appears that the units are shipped from there since they are in the US and Sagertronics is in China. I never received a response from Progressive RC, so I ended up ordering from Gearbest.
    The unit received is FW 1.10, HW 1.4.
    Curiosity got the best of me, so I had to open it up and check the spring posts. I dont know if its an improved design/material, but if it breaks I'll embed some stainless rods in it.

    Looks like you received the newer version. I took a chance and ordered one from Amazon. Just received it today. FW 1.03 and the sticker section not recessed. So not the newer version. It's going back unfortunately. I'm not going to shell out $100 for a charger and then have to worry that it may break. Since it was Sold by Sagertronics and Fulfilled by Amazon, Amazon's return policy is used.

    When you order it says by ProgressiveRC but below, sold by Sagertronics. Yes they are in China, but apparently have a warehouse in the U.S. Return address on the label.
    Sagertronics
    172 Trade Street

    I was wondering how they would deliver it in two days.

    How long did it take to get it from Gearbest?

    So I came home from work yesterday to find my MC3000 playing "Pong" on the LCD with the backlight on and making beeping noises as the ball bounced around. Why on earth would someone program a charger that's plugged into the wall but without batteries in it to do that? I pressed a few buttons on the front, but it didn't want to stop, so I just unplugged it.

    Well, I put in the feature request for a screensaver. But the beeping I didn't request! You can turn off all beeping (and/or the screensaver) in the SOV.

    Why can't it just turn off the LCD like a normal charger and act like it's off? There were no batteries in it.

    Because no one requested it as a feature, I suppose. Why not request it? That's how so many bugs got fixed and little features got added in v1.11, user feedback.

    Default Re: SkyRC — IFA 2014 — MC3000 charger-analyzer

    Here's a feature request/fix: Currently accumulated current over time (mAh) is always counted positively, even when the current is negative (discharging). On the display energy (Wh) is correctly counted as negative when discharging, but positive in DEX. The expected behavour and what I'd like to see:

    Discharging: mAh accumulates to a negative number, both on the display and in DEX. Same for energy (Wh).
    Charging: Remain as today, positive values on display and over USB.

    A second related request: I'd like the option to count energy in it's SI unit Joules (J) rather than Wh. Wh = (J/s)*3600s = 3600*J so it's a simple scaling factor but for me a more sensible way to count energy. A NiMH AA cell kepps around 10kJ of energy for example. As I see Wh being common around batteries perhaps this should be a user option to choose his or her preference.

    i am very pleased to announce that beta testing of FW1.12 (beta) and DEX3.2.8 (beta) has been completed, they work beautifully together. of course all versions are compatible with each other (1.11 1.12 3.2.7 3.2.8).

    the GIF shows how i'd test the function and look for bugs, i can't expect everyone to understand what exactly i am doing there, my extended testing procedure.
    yet some might find it interesting just to watch

    Hi Kreisl,
    Thanks for your dedication to this thread and charger!!!
    One question. I can see from your gif that you are still using Windows XP. Please tell me that this all works in a modern and fully supported OS such as Windows 10 including updating the FW. I've read quite a bit of this thread and have seen some posts that make me wonder if its supported.

    Thanks

    Has anyone measured the charging efficiency of the MC3000 in terms of Whr consumed to x Whr put in the batteries?

    Like a AA Eneloop has about 2.4Wh. So, if you're charging 4 of them with the MC3000, at say C/2 per battery, how many Whr does the charger use to put 9.6Whr into the 4 batteries?

    Similarly a 3500mAh Li-ion is about 12.5Whr, so how many Whr does the charger use to charge two of them at say C/2?

He told me all units shipped had the posts strengthened with epoxy to prevent breakage but are not the newly designed post. So in my mind this is not the newest version. Would or should this be of concern?
    I saw the insides of one of these, and there is a LOT of epoxy around the posts, so I doubt the posts would break.

    It doesn't play terribly nicely with W10 for firmware updates. I tried two until I found one that worked to get the FW update done from 1.10 to 1.11.

    I just bought SkyRc MC3000, and I got FW 1.03 and HW 1.4. Its from Sagertronics in Amazon. Is it not a pre-June production model with messed up pins? I don't wanna return it but I don't wanna sit on a $99 item which would go brick in few months or so. Help me decide, should I return it? Or am I being too paraniod? Seems like Amazon Sagertronics is crapshoot, u have no idea which version you gonna get and they still got 1.03 version.

    I calibrated my two units today - voltage and current. It was worth doing as some values were a little high, some set a little low - probably components settling in. Only thing, the instructions says to use a Fluke meter, but not a model number. Instead I used a Gossen Metrawatt M249A - link here https://www.reichelt.com/?LANGUAGE=E...FeEV0wodtzQBkg but I am not sure if this is as good as the Fluke mentioned in the manual. What model Fluke is suggested?

    @jaywalk,
    thanks for the input! although your ideas were already considered and decided against at an early design stage, i have relisted them as (UNCONFIRMED) instead of the stronger (NOT AGREED). both ideas would 'add' to the user interface and they're 'inoffensive': they wouldn't harm, that i agree!, and most people wouldn't care or even notice. The main reasons for the missing negative sign were iirc: 1) they are uncommon from a mass consumer's perspective, and other analyzers/softwarez/products/data publishers/reviewer/etc don't do it either, and it makes direct visual comparison of capacities harder in PCLS and DEX, and 2) afaik there is a space limitation on the LCD screen with a resolution of 18chars per line: "1∂4.19 -2.00 11000" fills out 18chars already, so where to squeeze in the negative sign? Next, multiplying Wh with 3.6 gives us kJ, very simple. If we discuss units, shouldn't we then also question the units of all other quantities (capacity, voltage, current, power, time, resistance) and consider alternatives? For 1 physical quantity one can find hundreds of physical units, e.g. for energy we have: J, kJ, MJ, etc, Wh, mWh, kWh, cal, Cal, kcal, Btu, thm, Ry, Ha, eV, ft·lb, hp·hr, l·atm, erg, sn·m, dyn·cm, and more exotic ones plus the Χ10³ engineering multiples. Upon every physical unit the maker's team took a decision and that was that. Since i am not strongly behind your idea, when i'd bring it up, it'd be off the table in no time. Also, since man-hours are limited, i'd rather have them work on other to-do's, see (k#71) or (k#61) which are both already existing options in GSV with 1 fixed parameter only and i'd love to see an expanded parameter range; again, most ppl wouldn't care or make use of the expanded range. Yet at least i'd feel motivated to motivate them to make time for that implementation task

    @ssalb,
    i have no personal experience with Win10. Some Win10 users get DEX and the FW update working on Win10, some don't. DEX site does not list Win10 as officially unsupported.

    @xdriver,
    firmware update through mac is not offered. but maybe(?) the maker will consider firmware update thru bluetooth app in future? the NC2500 allows firmware update thru bluetooth app, which is cool.

    @Stereodude,
    Design spec is:
    blank LCD = no power, or something's wrong
    when connected to power and no batteries = LCD displays NO BATTERY, with backlight on or off
    Charging efficiency is something which reviewers of charging equipment rarely look at because electricity is inexpensive (grid, mains, solar). And if someone measured 80% efficiency, such a number imho wouldn't mean much without a comparison to other similar chargers. It would be more instructive to measure the charging efficiency of the many different Nietcore i4 and D4 revisions

    @Minimoog,
    congrats to the user calibration! In the geman manual version it is called "Feinkalibrierung" (lit. fine calibration). Beautiful multimeter you got there! Never heard of the brand before. But with that price it's got to be better than any fluke dmm which the manual writer had in mind
    By the way the calibration is vely stable! After months of mc3k usage my user calibration points did not shift a bit. If your factory calibration proved a bit off, then it was like that ex factory

    Or apparently a rectangular block labeled MC3000 moving around the screen with a ball bouncing around off the edges and the moving block as well.

    Yes, I agree. If you're on grid the charging efficiency is a who cares. If you're off grid working out of a backpack with a small solar panel and Li-Ion powerbank you might care that your NiMH charger is only 40% efficient. FWIW, that's how efficient my LaCross BC-700 is. It uses ~25Whr to put ~10Whr into 4 AA Eneloops. Obviously the MC3000 is a little big to stuff in your backpack and use as a mobile charger in that scenario, but I'm curious of the efficiency and I will be measuring it shortly.

    Edit: Can't measure it today. The power jack isn't a 5.5/2.1mm barrel and I'm not about to cut the end off the power supply. I guess it's a 5.5/2.5mm barrel and I will need to buy one.

    I'm in the same boat as you. Ordered from Amazon beginning of the week. ProgressiveRC sold by Sagertronics and have the box sitting here. I only opened to check which version it was. Same FW 1.0.3 and the old case. Packed it back up nicely. I could have gone to the Post Office today to send it back, but its still here in the box. The fixed design has the pins for the spring perches integrated into the case vs just plastic pins going through the PCB of the charger. I suppose its always going to bug me.

    Maybe Kreisl can talk us out of sending it back.
