im going by the battery label ....

Yes, I think that may indeed often be ... optimistic

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.

cool i was wondering about that now im back to loveing this charger i also love my 14500 cells they test at over900 mah. i ordered 10 more of them

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

Thanks

got them here im new to this place but so far so good https://www.18650batterystore.com/14500-batteries-s/179.htm

im going by the battery label and a Zanflare C4. so i guess the labels could be cheating or at least they only get that mah under perfect conditions .

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.

Why do you mean by it "still" uses v1.14. What's wrong with that FW version, it is to all intents and purposes pretty perfect. Esp compared to the original FW release!

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".

But the MC3000 charger with 2 fan display this version : HW v2.2 ??

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

Re: 2nd gen dreamcharger presented on IFA Berlin 2014…

welli tested some new samsung q5s in the skyrc and they only showed like 2800 mah under the normal test. same battery's on my xtar dragon showed like 3004 mah. im thinking a returning the skyrc

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.

Re: 2nd gen dreamcharger presented on IFA Berlin 2014…

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

Re: SkyRC — IFA 2014 / CES 2016 — MC3000 charger-analyzer

How is your volt metre measuring capacity?

 

[raggie33]

Re: SkyRC — IFA 2014 / CES 2016 — MC3000 charger-analyzer

it isnt i was compering voltage at the time

Re: SkyRC — IFA 2014 / CES 2016 — MC3000 charger-analyzer

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.

Re: SkyRC — IFA 2014 / CES 2016 — MC3000 charger-analyzer

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

Re: SkyRC — IFA 2014 / CES 2016 — MC3000 charger-analyzer

ty for the input you 2 man i sure wish the battery makers was more honest

 

[almoped]

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.

Re: SkyRC — IFA 2014 / CES 2016 — MC3000 charger-analyzer

How accurate is the MC3000 with measuring internal resistance ?

 

[Nev]

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.

 

[fmc1]

The charger does not support delta temperature termination. It does however support negative delta voltage termination and the value is adjustable. I set Eneloops to 3mV, non LSD NiMh cells to 5mV and NiCd's to 12mV. They all come off the charger at about the same temperature using those values when I start with fully depleted cells.


It's been a few years since I used the PC app but If I remember correctly you can do some rudimentary functions with it like stop and start charging and set some parameters.

Hi,

Hope one of you kind folk could please help me out with my new mc3000

I'm trying to use 'refresh' mode to test the capacity of my ageing Samsung 30Q 3000mAH rated cells. I've set the cutoff to 3.2v and put 3000mAH in the program setting.

When i do the test, the cells don't reach 3.20v. It seems to get within 0.05v then in the rest phase, it creeps up and shows anything from about 3.25 to 3.3v before starting to charge again.

Firstly, is this normal behaviour for the charger or have I received a lemon here?

If it's perfectly normal, could you please recommend the correct settings for the capacity test?

Thanks
