You are welcome Smile

To be exact "up or down arrow until you reach the required slot number" should be "up or down arrow until you reach the required pgm number"

i correct it in my previous post

Google skyrc mc3000 cheat sheet and download the pdf.  The info you need is on the first page under “copy your favorite program”


 

Thank you. I have the cheat sheet, but it doesn’t explain that you can only copy a program that is the default program for that slot – you can’t copy a program that is just assigned to that slot and not saved as the default for that slot. I’m grateful for the quick responses on the forum to my request for help.

Edit: now I can see in the instruction manual the separate Global Setup View section where the default program selection and copy/paste method are discussed. I was confused by the Cheat Sheet and the other section in the instruction manual discussing the copying and pasting of a program from one slot to other slots, neither of which make clear that you can only copy programs set as the default for one of the slots. Thanks again for responding to my plea for help.

Has anybody had the graphs disappear from the LCD Display after updating to FW 1.4 ?

The way to access “graphs” view has been changed in FW 1.14 compared to previous versions — you now have to hold down (longer) either the Up or Down button to access Graph View.

I believe there are a few minor changes in accessing some other stuff in FW 1.14 compared to earlier versions. Can’t remember exactly which were changed — I also had to find out those information by reading the FW 1.14 documentation or check online to figure that out though..

Hello,
I have just received my Skyrc MC3000 from Banggood.
There is one problem. Some strange sound. When ventilators spinning faster it disappears.
I have done video of it:

Thanks

As I understand MC3000 doesn’t display SoC percentage after accumulator insertion. But my Ansmann Energy 8 Professional shows this information and it’s very convenient. Are there any tables for accordance Voltage-SoC% for LiIon and NiMH types?

Li-ion different chemistries have different SOC relative to voltage, sometimes very significantly different as can be seen in the bottom of this page

How “convenient” is that for you don't know, but one thing I can say for sure is that such estimation is inaccurate.

As JamesB says, depending on the mind patterns which define each battery (chemistry, construction and etc.) its voltage to capacity and energy curves vary. Therefore, for a device to optimally predict or know the actual battery SoC it must be designed with some specific battery in mind. Otherwise its accuracy will on average be acceptable at most. For example I have built lots of DIY powerbanks with different sorts of cells, and I can tell you their SoC percentage meter very often @#$%.

You can also use Henrik's cell database to check out hundreds of different battery discharge curves.

I know about different curves because of quality, age etc. Ansmann also shows only 6 stages on charge (0-20-40-60-80-100%). It’s not about accurate values but approximation.

Does anybody know why a single slot, in this case slot 3, will not read internal battery resistance? This MC3000 is brand new. Manufactured this year, bought from 18650batterystore, dual fans, newest firmware and I just got it a couple weeks ago.

Everything else about this charger is fabulous except this one slot does not display internal battery resistance. Either on the unit or in the app. Slot 3 seems to function normally in every other way. Tried multiple oem liion cells that the other slots display IR with fine.

Any insight would be jist peechy keen.

Thank you so much.

Some small manufacturing flaw can bring about such annoyance. Likely a reflow soldering defect somewhere in the board, or something like this.

Thank you sir. I'm not qualified to chase something like that down and whether I could solder it or not would depend on where it is.

Get this though. I restarted it and the slot is reading the internal battery resistance now undecided That's not a very encouraging sign, but maybe just a software glitch or something.

A quick update on this. It appears that sometimes I wasn't waiting long enough for the analysis to finish and or not getting a 21700 battery seated in the slot cleanly/quickly enough and the unit wasn't able to properly read the resistance.

Hi, I need help, I have a MC3000 for a few years and channels 1 and 2 have stopped working, not even detecting the battery when inserting it. Is it a known bug? Is there a solution?

I am sure the manufacturer has extensive support on this product.

I have 25 AAA Eneloops of varying age and most test under 100 milliohm, but three test above 200 using a 750mA (1C) discharge. Not a huge concern as I don’t use these in high-drain situations. Still, I’d like to play around with my MC3000’s cycling functions to see if I can improve these batteries.

Is there a recommended program for this? I don’t mind if it stresses or even risks further damage to the batteries as this is mostly to satisfy my own curiosity.

Thanks!

So I just bought one of these a week ago and am trying to learn to use it (I overbought for my needs and level of knowledge) Right now I’m just using it to charge Samsun R25 batteries for my vape mod but I plan to expand to using more rechargeable batteries around the house. I’m trying to create a refresh program for the samsung R25s. Can anyone tell me what the setting would be and how to figured it out so I can create my own programs without having to take up other people time every time I get a new kind of battery. Any help would be appreciated and thank you in advance.

You generally don’t refresh 25Rs or any other Li-Ion battery, there’s no point. Do you mean you want a charge program tailored for the 25R? If you’re thinking about NiMH (like enloop) batteries, the default “Eneloop Refresh Std AA” (or AAA) programs look fine to me. I did a little research since my last comment Smile

Understood on not needing to refresh. Is there any point to a tailor made recharge program then?

The Battle Pumpkin, if you want them to last the only care li-ion batteries need is to put away or store them not fully charged (short answer: don't go much above 3.9V). You can read about this and many other battery knowledge here: BU-808: How to Prolong Lithium-based Batteries @ Battery University.

Sure I can recommend a custom 25R program. First, you need the tech specs for your battery. 18650batterystore.com and others often have links. Yours is here:
https://cdn.shopify.com/s/files/1/0481/9678/0183/files/samsung_25r_data_...

So I put those numbers into a program exactly as those specs recommend:
BATT TYPE: LiIon
MODE: Charge
CAPACITY: 3200mAh
C.CURRENT: 1.25A
D.CURRENT: OFF
C.RESTING: 0min
D.RESTING: OFF
CYCLE COUNT: OFF
CYCLE MODE: OFF
TARGET VOLT: 4.20V
TERMINATION: 0.10A
RESTART VOLT: OFF
D.REDUCE: OFF
CUT VOLT: OFF
CUT TEMP: 45C
CUT TIME: 240min

Note “CAPACITY” is a safety number a bit above your actual capacity, in case you were wondering. CUT TIME is also a safety maximum above how long it should actually take.

You could change these (or add a second program) for faster, still safe, within specs, and get you like 90 to 95% charge in about half the time:
C.CURRENT: 2.5A
TERMINATION: 0.25A
CUT TIME: 180min

If you have other 18650s and you’re not sure what to use, these will be slow, but safe:
CAPACITY: 4000mAh
C.CURRENT: 0.75A
TERMINATION: 0.10A
CUT TIME: 360min

Sorry, I didn’t actually answer your question Smile

The point of a tailor made recharge program is to get full use of your battery so it runs the longest every day and performs well over hopefully several years, while charging safely and quickly. It’s a balance between these factors. Honestly any decent charger will be fine in 99% of cases but the MC3000 allows you to tweak things.

Hope the programs are useful anyway!

There is no point to refresh LiIon cells. You can run C>D cycle as per manufacturer recommendations (charge current, end of charge current, discharge current, end of discharge voltage), only to measure discharged capacity. This may be useful if you want to follow the state of wear of your cells. If you have a reference on the new cell, you may want to do it once every 30-40 cycles.
