FNIRSI HRM-10 Battery Internal Resistance Tester [ & Milli-Ohmmeter] Review
Paul T:
I am starting a topic on the HRM-10 Internal Resistance Tester - not currently one under Test Equipment. There was a brief discussion in Beginners to briefly discuss what the readings mean.
I just posted a review at: KeepOnTesting, please check it out.
As I said in my review, and on the other sub-forum, I felt the usefulness of this device to check the condition of old batteries was poor. I do capacity tests on rechargeable cells all the time, and the information it provides is much more useful, including the IR test it does (which needs done several times due to poor repeatability).
However, I found this to be an excellent device for accurately measuring milliohms up to 200 ohms. I haven't seen a good 4-wire resistance tester for about $35 before.
I wondered if anyone is using this meter for anything in particular, and how well it works for what you are doing? Has anyone made their own cable for the product? :popcorn:

I'm using one with firmware V0.4, although on their site there's only V0.3 available to download.
i use it to test battery cells in packs, and it's working nicely, it shows consistent results within specs. What I don't like is the short cable, and the clips come a little offset, but i will build some extra probs when i have some free time.

Fnirsi have sent one to me to review, it should arrive very soon, so watch out for a review on my channel within the next couple of weeks, if I remember I will post it here too.

Also got one, first impressions are mediocre.
Purchased it on sale from a store on Aliexpress (36$ delivered incl.25%EUVAT)
Dont like the connector, there is likely a reason why they tend to use specialty connectors where some seem to originate from aviation on cheap resistance/milliohm meters.
Is it a GX12-4pin on HRM-10?
Trying to find heads & tails of the different models.
* Yaorea 1030+ USB-A 4pin
* Yaorea 1035+ XS10 4pin?
* RC3563 GX12 4 pin?
* HRM-10 GX12 4pin?
* Yaorea 2050 USB-A 4pin
Correct?

Why you say yours is mediocre? in what scenario's? I find mine really competent in diagnosing lithium batteries health, it's easy to find a failing or bad cell in a pack. The cable is really not good, and the clip solution is not adequate for bare cells, the pin type is better but the device reads fast and comparing to hioki BT3563A and BT3554 it does not disapoint.
