This is definitely not a review, but just my first impression from the MC3000 (It was supplied by Gearbest).
If you are thinking about preorder or not, this might help a bit.
The charger looks like any other analysing charger at first glance, but it is considerable more robust and the functions are not exactly the same.
It has multiple user interfaces, the simplest is a "dummy" interface that is very useful for people that ordered the charger without realising what it is. To really use the charger you need to select advanced user interface. This also means that you cannot just drop a cell into the charger and charge it, you have to fill in a specification on how to handle the cell. You can save these specification (Up to 30), but has to remember the number.
It looks like the charger can do a lot of stuff, but I am not very far in my testing yet.
I have two charger curves ready:
This is a perfect LiIon charge curve.
This is also a very good -dv/dt charge curve.
I do expect the final result will be very good, but it is some weeks away, where I will charge/discharge/test many more cells. I.e. do not take this report as my final conclusion.
Until now the only negative impression is the user interface, but with all the functions in the charger it is very hard to make a easy to use user interface.
I am thinking very hard about replacing 6-7 of my most used charges with two of these, the only hold back is the user interface.
PS. I have not played with the computer and phone interfaces yet, maybe they are easier to use.
Some comments about the user interface (I have not really looked at the test data yet):
I do still not like the numbers, when looking at the charger I just get four numbers for the slots, no information about what the slots will do.
If I want to see what is hidden behind a number it is just one keypress, then I can see the program, use up/down to change program number and enter to confirm program number.
To start the programs only a short press on enter is needed. I.e. if you put in a new batch of batteries and the shows program numbers are correct, just press enter to start.
When you change a program, like selecting another charge current, some other parameters in the program will also change, i.e. to get exactly what you want it is a good idea to check the full program, when you do a change (Selecting a program will not change it).
My guess is that I will need 6 LiIon charge program, 4 for 4.20 volt with different currents, one for 4.35 volt and one for 3.6 volt. I might need one more if the charger can charge at very low current, but there might be problems with termination (I will have to look a bit more on that).
During charging I have sometimes checked my voltmeter and the charger display and they always match within 1 digit when charging LiIon.
