I need help with cell balancing

[FriedRice90]

Hey, guys! I really need your help.

Tomorrow I want to go for a long drive, but unfortunately, I have some issues with the charging part. Last week I had to buy another charging cable because the original one (110V) failed. So I bought an after-market one (240v). The car charges fully, but I am concerned about the cell balancing. So I used the AlphaOBD and I noticed that the cell with the highest voltage at 100% was the same as the one with the highest voltage at 4%. Also, the cell with the lowest voltage at 100% was the same as the one with the lowest voltage at 4%. So, this means the cells are not balanced. I tried to do it using the OBD. But it didn't work.
Am I missing something? Do you know if the car needs to be in a specific state for the balancing command to function?
Also, could be the charging cable a factor?
I really need your thoughts because tomorrow I have to go.
P.S. The car is a 2018 Fiat with a range close to 100 miles.

I stumbled upon these Imbalance Check instructions online and thought they might come in handy for you!

Just a heads-up, the pic isn’t mine - credits to the original owner for that! Hope it helps!

Looks like the car is always trying to find its sweet spot when it goes from 99% to a solid 100%. Little hiccup usually pops up with those aftermarket cables, which sometimes just don’t cut it when it comes to getting that full charge. Btw, what’s your battery sitting at when it’s maxed out? And have you taken a peek at it when it’s lower?

And just so you know, AlfaOBD is set to save logs automatically on the device you used for the scan.

Charging it up to 100% every now and then isn’t really cutting it for balance, yeah? Feels kinda pointless, doesn’t it?

Hey, everyone! I managed to get everything balanced and ready for the long drive. Turns out the aftermarket cable was causing some inconsistencies with the charging. After switching back to a higher-quality cable and running another balancing cycle, the cells leveled out much better. I am sorry it took me so long to come up with an update. I really appreciate your responses!
