    Default SkyRC MC3000 "capacity" Reading - Conflicting Info

    I've had the SkrRC for a week now (latest version), and for the 1st time did a refresh (capacity) test. There seems to be a conflict on how the main unit, app, and PC link are reporting "capacity". The example below is for a 5,000mah Powerex C Cell.

    When the refresh test is completed, the main unit shows both the:

    "capacity": 4817mah
    and
    "charged": 5183mah



    .
    OK, I understand the difference between charged/discharged capacity, nothing unusual there.

    However, both the PC link and app show "capacity" as the higher value - what the main unit is calling "charged".


    .


    .
    Would this not be confusing? It appears the main unit is defining "capacity" as the discharged capacity, and the app/PC Link are defining it as the charged capacity.

    Shouldn't there be consistency between main unit, app, PC Link?

    After more observation, I now see that the app and PC Link are showing the results of the last phase of the 3-part test (C/D/C), in other words the charge portion. I think it would have been better if the app and PC Link labeled it "charge capacity" or "C capacity" for clarity.

    Edit update: Found this issue discussed by someone who noted exactly the same thing HERE:

    So what gives with the reporting of capacity on this charger?

    I ran a refresh cycle overnight on 4 batteries: 2 AAA Eneloops and 2 18650 LiIons.

    Slot 1: Eneloop AAA
    Charger reported capacity 742 mAh
    iPhone app reported capacity 867 mAh

    Slot 2: Eneloop AAA
    Charger reported capacity 767 mAh
    iPhone app reported capacity 906 mAh

    Slot 3: LiIon 18650
    Charger reported capacity 3153 mAh
    iPhone app reported capacity 3125 mAh

    Slot 4: LiIon 18650
    Charger reported capacity 3086 mAh
    iPhone app reported capacity 3069 mAh
    Also, from one of the MC300 developers in that thread:

    Whatever the LCD displays is the correctest. Correcter than PCLS (a software which sometimes fails to log the very last 4-6sec of a test run, missing in the CSV dump) and correcter than APP. The LCD is your friend. She doesn't lie.
