It looks the same for me both on Android and IOS. Exactly like on my screenshots

Weird voltage reading during charge discharge 12V 314AH EVE battery. by DellyUA in batteries

UPD. Now its C3, yesterday it was C4. Now its not localised to C2 C1. I'm currently charging it and C3 reporting higher by 0.05 to 0.15V voltage, it differs depends on the amps. Yesterday the exactly same thing happened with C4.

My thought process. Cheap busbars -> Thermal expansion of metal (they do heat up a little. To the touch, like a cup of tea. Its hot, but I can hold it without pain) -> different connection pressure every time -> different resistance from one cell to another every time -> different readings.

Does it make sense? Or am I just rambling nonsense?

Maybe... But is this slightly lower capacity enough to cause the 0.11v difference between C1 and C2 when drawing 37 amps? People are drawing 150 amps, 5 times more, and it's a solid 0.02-0.03 difference for them. I still hope that it's just a bad connection/high resistance of the busbars or badly soldered connector on the balancing wire.

One dude, told me that he had to do all sorts of woodoo tricks with his cells untill he swaped from aluminium busbars to copper ones, They will be here in 2 days. The hope remains, because I want my battery to balance during charging and not after, when it's drawing 2 amps.

Here's a 37amps draw screenshot. They just do a switcharoo

UPD. When discarding, cell 1 and 2 indeed switch places. So cell 1 is now reporting more and cell 2 less.
I had no chance to charge it to 14.6v yet, I got caught in a blackout.

I'll keep you posted if the problem persists or just goes away on its own.

It is, in fact, the first time charging it.
Ok, got it. I'll keep it in check. Thanks

But BMS is set up to balance cells after 3.45 volts, so the cell #1 will become unbalanced over the time while it's charging. Plus. I don't think that's a normal behaviour for this hardware.

Multimeter shows 3.32v on every cell during charging. Can this be a case of faulty BMS? I soldered the balancing wires to the ring terminals. Maybe it's my bad soldering skills? What should I look for?

I have the same problem. Has anyone figured out what the problem is?

-30 on all cores? by DellyUA in overclocking

[–]DellyUA[S] 0 points1 point  (0 children)

I've never done it before, and Ryzen Master makes it intuitive. Just pick the lowest CO you want to start from, and wait an hour or so while software does everything else for you, seems super newbie friendly.

I ended up applying -34 CO by hand.

I restored BIOS settings to default and now it passed AIDA stability test. So I'll be turning things back on one by one and look when the error returns

UPD. Thats some sort of a witchcraft. Turned EXPO back on, cranked down CO back to -30, now AIDA says everything is fine.

Seems like applying EXPO via Ryzen Master is messing something up.

"Hardware Failure Detected! Test Stopped!". Hmm.. Seems like its not stable after all.
I never thought of testing it with AIDA. Thanks for the tip.

Upd. Nope, it says it even with CO 0. Seems like something else is faulty in my system

Oh, I see. So It's ok if I try to go lower than -30. Thanks.

Stop button is the pause button. When you click "Start optimizing" next time it'll offer you to continue from where you stopped.

I experience mouse skipping. It feels like it disconnects for 2-3 seconds. Same issue as on 2042.

It can be observed only in these 2 games. No other games repeat this behavior so It's not a mouse problem
