SkyRC MC3000 help thread

All of my protected cells trip at 3 volts.

Oh geez. Super annoying :wink: I have some cheap 18650 battery holders with wire leads which I connect in parallel to the battery in the MC3000 to get the charge started.

I’m hoping to find some kind of decent charger online that will give a low voltage liion cell a charge without giving a damn about the starting voltage, since this practice of encountering low voltage cells is rather uncommon, but a huge pain in my ass when it does!

On the skyrc mc3000 you have to hold down the number slot button of the bay that the cell is in, it will then activate that cell.

This is copied & pasted from the manual,

I’ve placed a flat top protected 18650 battery in the bay yet the slot info is stilldisplaying NO BATTERY. How to proceed?- Check if the battery is inserted with correct polarity. Check if the battery terminals do makeproper connection with the slot metal contacts; shift, suspend, or tilt the battery, if needed forsecuring the connection. 0V-batteries are displayed as NO BATTERY, so check if the batteryprotection is tripped; click the slot number button to release the protection

Isn’t that just a feature to reset a tripped protected cell? I’ve tried this on a unprotected 2v 18650 and it just doesn’t work to charge that battery, the charger still aborts with some kind of voltage warning.

It works with mine , maybe the charger is telling you the cell is no good!

Try pressing the number slot button repeatedly.
Edit
Did you hold it down for long enough until it recognises the cell?

I need help. I just received my new MC3000 a few days ago. I’ve saved six charging programs, and I can see why this charger is so highly regarded. The charger seems to be charging NiMH and Li-ion cells correctly. I have a problem, though: I can’t get the charger to copy the program saved to one slot to all of the other slots.

I have tried the following procedure several times: 1) saving one of my programs to slot 1; 2) clicking the Slot 1 button and the up arrow button at the same time. When I complete steps 1 and 2, above, instead of copying the program saved to slot 1 to the other three slots, the charger saves “Program 12” to three slots I have not programmed. I have not created a Program 12. I have no idea what I’m doing wrong, and I have no idea why the charger is doing this. Can someone help?

Thanks in advance.

This mean that the default pgm for slot 1 is pgm 12 instead of pgm 1

To set the default pgm for slot 1 you have to

  • press the stop button until you enter setting
  • scroll down with down arrow and find the "SNB# 1 Memory" line
  • press enter
  • up or down arrow until you reach the required pgm number
  • press enter
  • Long press enter to save and exit setting

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

The cheatsheet is very helpfull and i second downloading it if you haven't done that already but it doesn't explain that, iirc the full manual does

Merci bocoup! Neither the instruction manual nor the “Cheat Sheet” on the SkyRC website explain that! They seem to say you can copy any saved program selected for a slot to the other slots - which is apparently not true, unless the program is the default program for one of the four slots. I appreciate your help.

Edit: looking at the instruction manual discussion of the Global Settings View, I can see that it does talk about setting up the automatic copy and paste of up to eight saved favorite programs with the slot number buttons and up and down arrows. However, in the section on using the Total Overview, it says you can copy and paste programs stored under a shortcut. When I read that, and I looked at the Cheat Sheet, I had the impression that it was possible to cut and paste any program saved to a slot. Not true! Now, thanks to the help you provided, I can see how the process works.

You are welcome :)

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

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…

That was it exactly, cheers!

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.
