Hi guys,

i am a proud owner of a nazgul 5 v1 6s. Last week i noticed in the OSD that the battery voltage was 33v, pretty strange!!! I watched some tutorials online on how to tune the BF battery readings and all seemed solved, but than i noticed that after a long flight now the battery never went below 24.8v, and this doensn't seem normal too.
So i tried to tune BF with 2 lipos, one of which is full (25v) and the other at storage voltage.
I can't figure how to properly set the values in BF correctly, because when i tune BF for the full battery and shows the correct voltage, when i connect the other battery (at storage voltage) BF shows completely incorrect values, nearly 24.8 instead of 22.2. And the same happens when i start tuning with the storage voltage battery and then connect the full one.
In this situation i can't have realiable voltage readings in my OSD.

Do you guys have some advice on how to fix my issue, Thanks
(BTW sorry for my bad english i tried my best)

That sounds like a really weird issue, especially on a BNF quad. The voltage calibration should just work as it was configured from the factory. Did you try going back to stock settings as were supplied from the factory to rule out any changes you might have made?

Can you please run both the "dump" and "diff all" commands in the Betaflight Configurator CLI tab and copy/paste the results back here.

I changed FC and ESC but i don't think this is the issue because they worked fine until last week. I bought the exact same components that were in the nazgul originally.
Btw those are the dump and diff all:

While I don't have the Nazgul, have different readings in Betaflight, by goggles, a battery checker and a multimeter. Not sure which one is right.
