Has Miboxer C4-12 been upgraded with new flashware, fixing the C3 Error, restart problem, overcharging, inconsistent resistance measures and with upgraded sliders, etc.? Should I order at Banggood, Gearbest or Fasttech to get the most recent version minimising the risk for any of these issues?

Only one person can answer and he might not be watching this thread anymore.

Maybe someone ordered recently and can say something from experience?

I still got no answer from them about my faulty charger Sad

Sorry, but the recent buyers are not going to be able to tell you anything other than they bought it and it works or doesn’t work. They can’t take it apart and see any internal changes or see software changes.

Maybe they can measure the height of the lowest bump on the outboard slider to see if it’s been raised slightly?

To get of those other questions answered you need to ask Leo-Miboxer and even he probably can’t tell you what store is selling the most recent version. He might can say who has bought a recent batch, but that store might still be selling an older version.

You are probably right. I guess I expect too much…

I’m just trying to lower your expectations. Big Smile

I don’t think they can fix all the things you mentioned since some seem to be very rare events, but maybe they have made upgrades in a few areas. I think the vast majority of buyers, like myself, have had zero issues. I bought mine in November.

Does Miboxer sell direct? Maybe you can get one of the latest versions from them?

Well you did Smile

I just wish to have upgraded sliders, on my unit I had to use magnets on negative side to be able to charge 26650 batteries and I don’t like that. All other problems are less important to me as I believe they happen only sometimes or not at all.
I bought C4-12 mainly for charging 26650’s and it was annoying to deal with magnets to make it work.

I still wait for some answer from them, will see if I ever get it.

I took a razor and trimmed the tubing of my 26650 cells that had an issue. That fixed that.

Another good charger for 26650 is the Xtar SV2 Rocket. Sometimes they are on sale for under $20 (Currently about $23 on Aliexpress). They are 2 × 2A. A lot simpler. 1A is default, click the button once and both slots go to 2A. Done.

I still use 2 of them as backups.

I will check SV2, thank you.

I have to order something, now I only have one Lii-500 and nothing else to charge cells.

On the most recent Miboxer C4-12 package, there is no 3 years warranty mark. I found two Youtube movies with that package. Seems like it has been on the market for at least 3 months. I’m not sure if it got new firmware or if sliders are modified, as it is difficult to see small changes of 1-2 mm in the movies.

I’m trying to figure out where to buy it for a reasonable price at maximum $40 incl. shipping, and not found where yet. Amazon will not ship it to my country. Has anyone here receive that charger without warranty mark, where did you buy it for a good price?

C4-12 New version Movie 1
C4-12 New version Movie 2

Can you see any difference? New (and 2:28) vs old C4-12 sliders

Chris review on Amazon also has some good pictures of the newest.

Have you checked with Freeme or M4DM4X? One of those two had a coupon code for it that was under $40.

Update on my problem. I got in contact with manufacturer and we will try to work things out.

@RapidLux
I can actually see difference (or I believe I can). Most visible is slider part that contacts – of the battery when charging should be at 90° angle, on my is bent backwards.
Picture to show how it looks on my charger (not my picture). Look at slot 4, on my charger all 4 slot are like that.

Question is, if they will ship the old or new version. Fasttech has a good price too, but replied they couldn’t answer my question. I’m waiting reply from BG and GB, we will see what they have.

I just got replacement unit from Miboxer. They have great support (you just have to be patient to get answer) and sent me replacement by DHL at no cost.

You can see upgraded sliders and difference below:

I forgot to mention new sliders are perfect fit for all cells I had problems with before, all have good contact. Thumbs Up

Btw. sorry for dust in pictures, taken in garage and we have roadworks in front of house so there is dust everywhere Facepalm

BG confirmed they now send the new version without warranty mark, that, I’m pretty sure has new sliders. BG said even without warranty mark, they will solve any problem. Miboxer works on a new firmware for C4-12, it hasn’t been released for market yet, there will be no change in functionality. I think very few had firmware problems anyway, you will probably not notice any change.
