    usually the cell manufactures state the capacity down to 2.8volts & sometimes 2.5volts, so if you only discharge to 3 volts , the capacity will be less.

    Can you please comment on the source for such batteries?
    I am also looking for reliable 14500 batteries.

    Thanks

    What are the settings on your program?


    If you set the capacity to 1000MAh for example and left everything else as default you will get very conservative results. Discharge current will be .25A, cut volt will be 3V and d. reduce will be off. All of those settings are conservative. If you want the best numbers lower the current to .2A, lower the cut voltage to 2.5V and set the d. reduce to .05A. If after doing that and your results are unsatisfactory you more than likely have a bad or fake battery.

    I agree, FW v1.14 has been flawless in my use after I figured buttons to view graphs had changed.
    I had impression FW v1.14 could not show higher HW version number, that's why "still".

    My two fans version don't show HW v2.2 in setup, but ≥1.3. It is bought from NKON at last June.

    Consider that charging current, discharging current, and end voltages can differ, resulting in different values for capacity.
    I'd rather return the X-star as the source is a better rated charger.

    yeah but i have 2 chargers who agree with each other and they are very close to what is on the battery label and my volt meter says one thing the skyrc says another thing

    How is your volt metre measuring capacity?

    I would be very careful about how you're measuring and what, before you return your MC3000. It's much more likely your other devices are inaccurate, not the MC3000.

    The fact you are "Seeing the values on the label" is an instant red flag, Batteries almost never match their label except under extraordinary conditions.

    On the MC3000 it is easy to verify calibration and do you own calibration, at least if you have a good DMM.

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

    Does the charger support temperature based, dT/dt, termination?

    Is it possible to control/stop charging of a battery over USB? I wonder if nongnu DataExplorer could be used to implement dT/dt functionality.

    How accurate is the MC3000 with measuring internal resistance ?

    Default SkyRC — IFA 2014 — MC3000 charger-analyzer

    on the molicell 26 I get 17 , on 30q I get 28 on LG 3000mah I get 19, I would say it's one of the best & it's very consistant on every bay.
