It also is consistently high unless you get down to the very low mΩ cells.

But it's not consistent on how far off it is Confused
Some times it's off by 10, others by 2 or 3, there's even a 13 difference. It may be consistent on reads, but not reliable on accuracy for some reason.   Huh

Thanks Wolf, I've been waiting for it. I'm seeing a pattern that as the capacity increases the delta increases. Maybe it'll be more accurate if you test full charged batteries.

I will do that in the next couple of days I hope. And won't keep you waiting this long. Tongue

OK charged all the cells on my  3 LiitoKala Li500

Here are the results of the test between the ZB206+ and the YR1030.
I have included the Voltages the cells came out of the charger with.

Hi Wolf!
Did you measure the IR right after charging?

Yes I did.

For My next trick I am charging 12 UR18650FM cells.

I will post those results tonight or tomorrow.

For more stable results it's better to take a 15min pause after charging (30min recommended)

Oh that I did, at least 30min for sure.
Takes that long to get setup with the spreadsheet anyway. I wasn't planning on repeating this so I didnt save the format.
Foolish me. Well now I have so bring it on. Big Grin Big Grin

Here is the results or the UR18650FM cells.


And these are in the wings 6 INR18650-13Q high drain low IR cells ~26mΩ
Also 6 ICR18650-20C low drain high IR cells ~75mΩ

Then your voltmeter must be wrong because after 30 minutes the voltage can't still be 4.199 or 4.203V

Really ?

Voltmeters tested with my reference board.


I will check them again.
All of them
