Charging 2 lifepo4 batteries of different SOC..what happens??

A lot depends on the type of battery. LiFePO4's usually have a BMS built into the battery case.
Thank you for adding "usually." I've noticed that nowadays an assumption can creep in that LFP have built in BMS's as a rule.

I would add that those in-battery BMS systems work entirely on voltage, unless there is a shunt in the battery. When voltage becomes disconnected from SoC relying on voltage only becomes problematic.

That's exactly what happened in the experiment

You dont have any idea what you are talking about and I cant let you spread false information. Literally everything in the above post is wrong...completely wrong. All of it. And every sentence continues to show you are WAY over your head. Please, I implore you to research more before making these proclamations.
 
You conducted two experiments with hand-written results. We disagree on the interpretation of the observations.

I've suggested several further experiments that can resolve our differences. We don't have to start insulting one another.

Is this wrong? Tell me how/why

We know that happened because of your first experiment, when battery voltage changed rapidly and permanently without a fast corresponding change in SoC.

Tell me where I'm wrong.

You have been told for 9 pages but you insist on making up your own conclusions. You are way off base and keep posting incorrect information that someone later may read and take seriously.

You haven't discovered an angle that no one else sees. You are incorrect in your interpretation and your conclusions. You might want to let this one rest.
 
I hijacked one other thread in my attempts to understand all this. Sorry to ksanders. It also solves my puzzle over SoC, and my assessment of twistedtree's system. Sorry if I insulted anyone along the way.
Problem with Balmar Mc614 and LiFeP04

I have. You haven't told me I'm wrong, let's discuss further. Or not.

I'm not trying to convince anyone. Run one of the tests I've suggested, come back with the data and we can reconvene.

My explanation fits perfectly with the data presented so far. I'd be happy to be proven wrong, here. It doesn't take a lot.
 
If I'm contradicting a bunch of professional YouTubers that doesn't convince me. Sorry. Show me the data.
 
I thought we'd switched to BMS talk before the rude interruption
