Yes the YR1035+ is a very good Voltage and IR reader. I own just about every sub $100. 00 IR meter from the humble YR1030 (which built my first 14s80p battery) to my favorite the RC3563.
If you read the complete thread I highly recommend the cell holders to measure the cell with. The probes no matter how you use them are clumsy to use for the 18650. You need to use 2 hands (duh) and you have to memorize the readings if you are going to record the results in a spreadsheet.
So unless you have someone to enter the numbers or have a photographic memory I ended up doing the measurement twice once for Voltage and once for IR. The cell holder will keep the measurement and it is very easy to copy both numbers. The RC3563 with the cell holder, the USB interface with a bit of py and VB code this process can be automated.

The probes on my YR1030 which were chintzy at best but did last and are still useful, Your leads are much better encased in plastic rather than shrink wrap. Still my recommendation is the cell holder.

I really appreciate your enthusiasm and dedication to the testers, I wanted to inform you so that you can expand your collection that BRT808 came out at the end of last year and now the newest thing is YK-VR1220H since it incorporates two more buttons and measures up to 120V

I hope you can acquire them and put them to the test ✌🇨🇱

Hey, I was just about to buy a RC3563, and I get to the end of this thread and see the YK-VR1220H mentioned which seems to be the same thing with a few more features for the same price (or slightly cheaper). @Wolf do you think that's a good choice - or would you suggest the tried and true? I did cobble together my own 1kHz 4 wire AC IR tester (see photo) but it uses two multimeters and it's kind of a pain to use (I have to divide two numbers for each cell I test - lol - you mean I have to do math?) and the battery holders that are available look very nice (my finger tips are getting dented...).

I will say I just recently tried to measure some very low IR on some LiFePO4 cells (0.16 mOhms) and while the 1030 handled it no problem, the 3563 did NOT like it at all. It just kept bouncing around all over the place (all below 0.25 mOhms).

I would stick either with the YR1035+ or the RC3563. There is no need for the additional options and it just clutters up the interface.
The one thing I like about the RC3563 is the USB-to-UART Bridge Controller interface. You can also hack the YR1030/35 by adding a CP2102 chip to the main board. I use it to automatically enter the Voltage and IR straight into my excel sheets.

Hm interesting. Although on the LiFePO4 I am assuming you are measuring 16mΩ did you use the Auto setting on the RC3563?
I had absolutely no problems with at least my RC3563 measuring a 10mΩ reference resistor and it was rock solid. 9.926mΩ
Also testing just resistance between solder/cell holder/busbar 0.946mΩ. Also just a small strip of copper wire 0.069mΩ all rock solid.
Not saying you are not experiencing an issue just curious as to why. Maybe its the difference between the YR1035 using relays to switch modes and the RC3563 using electronics/mosfets rather than mechanical. IDK. I have some LiFePO4 cylindrical cells (A123) I can check just to see.
It of course goes without saying that I have tested the other mΩ meters I have esp the YR1030/ YR1035 etc.

Not 16 mOhms, it was 0.16 mOhms.
I think that is just too low for the R 3563

I do stand corrected 0.16mΩ Nice!
But as stated above ^^^
Also just a small strip of copper wire 0.069mΩ all rock solid.
Which is 0.069mΩ well below 0.16 mΩ

So again not sure what is happening with your RC3563 but in my case it reads low mΩ just fine.
Again not saying your RC3563 is not happy with this low of an ohmage and I certainly don't have as much experience with ELO (Extreme Low Ohmage) nor the Electric Light Orchestra as you have with the LiFePO4 cells.
According to the RC3563 specs it should measure Resistance: from 0.001mΩ ~ 200Ω and they are of course just specs from china which we all must take with a grain of salt.
So in the long run I suppose having an YR1035+ and a RC3563 is a given. Although now with the help and guidance of @Oleksii I have the YR1035+ talking to my PC and can also import that data to excel.
For standard 18650 Li-Ion harvesting I still stand by the RC3563 as my favorite, and with the CP2102 chip mod on the YR1035+ a very close second.

Perhaps mine was just weird. Since I have two RC3563 and YR1035+s. So I got covered whatever I need.

Low battery in the RC3563? I have found when The battery gets low in my multimeters, or YR10330+ the meter readings swing wildly.
