Like this? https://secondlifestorage.com/t-LiitoKala-Nitecore-Opus-XTAR-Zanflair-Chargers-Testers

Wolf: Mind if we download the spreadsheet so we can have the attachment local? You would just need to inform us of any updates so we can replace the file.

Please do. It has some other info on it. Kinda playing with guessing capacity of reclaimed cells and the YR1030 Tester results.
But yea I will keep you up to date if any changes happen.


Thanks :)

but what about cutoff?

I'm sure that liito stop at 2.8V , Zanflare 2.7V and Opus 2.8V (or near)

I know that in 0.1V there are not much mah, but that can be some.

In my test, opus/liito give more or less same result - zanflare 5% more (on average)

My tests for these charger /analyser was out of the box with a brand new set of 4 cells.
There was no analyzation of the analyzer as per say.
The purpose of this test was to see what differences there are between these units as far as mAh, IR and just general usability.
I have taken my Zanflairs (3 of them) off line as in my testing they were consistently high 8 to 11 percent. same 4 brand newbatteries in all the charger / analyzers.

I have just purchased 2 more LiitoKala and 2 more Foxnovo chargers as they seem to be the closest to the rated cell capacity.
After running over 300 salvaged cells through the Zanflairs and getting over rated capacity readings with a moderately high IR cell I am questioning the accuracyof these units. If I had all Zanflair units I would never be the wiser and go merrily on my way without a second thought.
Same goes with Opus, LiitoKala, and all the others. If I had stuck with one brand I would never have done this test. I guess that will teach me to have an inquisitive mind.
I should have just stuck with the Opus. :(

So I say again anybody want to buy 3 Zanflairs cheap?
I will post them in the marketplace this weekend.

That's why it's recommended that what ever testers you have, always use the cells tested in 1 brand/unit to make a string, and use the other cells in another tester to make another string. Don't mix the two together. That way the whole string is built with similarly rated/tested cells using the same algo and equipment.

The XTAR Dragon VP4 seems like a good swiss knife. I looked at ebay and I'm not really sure with the pricing. Top results is USD29.99 with free shipping, then 39, 49, 59, 89, 99. I wonder which is which.

I bought mine fromhttps://www.18650batterystore.com/Charger-p/xtar-dragon-vp4-plus.htm
I am not affiliated with them but they seem to be a reputable company and their prices are reasonable sometimes they even put them on for the deal of the day if you have patience.
I have also seen the price differences but you gotta be careful.
Some of them charge shipping like $30 or so and some may be fakes I don't know.
The real ones come with a Scratch and Check validation serial number on the box. Mine had one and so it was a true one.
Also the ones from China or Hong Kong take forever to get here and it's tough to negotiate a return if it's not what its claimed to be even with ebay buyer assurance.
My 2 cents buy from a US dealer and be happy.

have anyone tested voltage reading accuracy of this tester? i've find that 4.20V cells in Zanflare is 4.22v in Opus and Liitokala, while on multimeter is 4.19V.

Quite interesting to see your OPUS chargers being so accurate. My 3 units have 8-12% inflated values. And these are the best 3 units if found. Placing 4.20V cells into the units they show, 4.17, 4.20 and 4.22 V (at least the same on each of the 4 slots). I had a unit that showed 4.11V and one that showed 4.28V, both of which I returned.
Interesting is also that your 2 OPUS units have consistent results while on all 3 of mine the right most slot always has another 2-4 ish% percent inflation over the other slots.
Starting to think that maybe the 110V units are more accurate???? is that even possible?

The Foxnovo 4s I have also found to be very accurate.

Thanks for the tests!!!!
ive considered changing dischargers but I have 2000cells here all labelled and marked, cant be bothered adding new ones with more accurate readings and then they dont match other cells.

Hello The-J-Man,

Testing the chargers is an interesting thing and you may be right the 110 may be more accurate. Why?Itwould not make any sense though as the input is just 12V DC coming from the wall transformer that shouldn't matter whether 220V @50hz or 110 @60hz. But I have seen weirder things. :)

I am constantly running different test on all 3 of the major brands here is my latest sheet of that. It appears the slot to slot difference is marginal at best

There is more analysis on my google sheets share with the harvested cell analysis.xlsx. the last sheet in the file "Tester Comparison" The Zanflairs i just use for charging now as its too cold in the shed to fire up my 40 cell charging board.

Hello all been really busy on my IR project and have 1175 cells entered nowon the road to 3000.
Results as to percentages of cells over 80% remaining capacity. Cell count is a little different as 1175 have been entered and 1144 have completed the test.
Just in case you wonder why the numbers don't add up :p

image_ihebcg.jpg


The current cells that I am testing are the previous 700 that I already ran through the testers but never recorded so that is what I am doing now.
Recording theIR and retesting them so the results are going to be pretty good as these cells have already been checked for SD and did meet my 2200mAh lower limit.

As soon as these get done I will get back to cracking batteries as I got 150 or so still to go before I pick up another 200 at the end of the month.
In the meantime I have been dedicating some chargers and slots for a slot per slot and tester to tester comparison and here are the results.
Hope you find it informative and interesting. :)

Update:
I was going to ask Korishan to add this to the FAQ on Charger tests but I see its gone.

So here is the newest update

I have just finished my analysis of the RC MC3000 Charger/Analyzer and boy am I impressed. I guess I should be for $110.00.

image_jtrkbr.jpg

The SKYRC MC3000 is a beast it is heavy and big substantiallybuilt and it looks tough.
It took me all weekend to figure out all the settings and options but I like it a lot.
The great thing is that all your charging and discharging parameters can be adjusted to the cell spec sheet.
Like CC/CV mA charging cut off. Cell discharge cutoff V and mA. Obviouslyvery granular charge and discharge settings.
The sliders feellike there made out of half inch channel iron and you have to use your finger to slide it back and insert the battery. You really can't insert a cell just by pushing back the slider with a cell. All slots are totally independently programmable and give detailed information at any time.
Not like the OPUS which doesn't give you a mAh reading till its done that has always bugged me on the OPUS. All the others do this why can't they?
So the results.
IR is eh OK not on the money as 4 wire is the only way to go but acceptable as a "reference".
The mAh tests areright on the money especially if you set up all the charge anddischarge parameters according to the battery spec sheet.
I like this Tester it's the price I do not like but hey I guess you get what you pay for.
It has a great PC interface were you can program each slot load it and run it and it graphs to boot. Temp sensing of course etc etc.
Bluetooth is also there but I haven't done anything with that yet.
It has a reasonable fan underneath that is temp controlled and comes on as needed. It is not the quietest but it doesn't scream at you either.
Beeps can be turned on and off for a multitude of announcements and octaves can be changed.
I tested my new control cells the Samsung INR18650-25R and theresults were well.... excellent right on the money.
I took this opportunity to test 4 Sanyo UR18650FM cells that had been tested on my Foxnovo (modified by removing the annoying speaker)and popped them into the SKYRC. Well I can say that the Foxnove is not bad. I will check the OPUS and LiitoKala also. The Zanflair I will do if I have the time but I know the outcome.
I am waiting on the return of my iCharger X6 and will have those results as soon as possible.
Well that raps up my charger testing report for now pictures attached.
