Battery cell deviation

[TimN23]

Hi,
It would be nice if, for each battery, the cell voltage and cell deviation could be obtained in comparison to each other, instead of the total voltage.
Dead or damaged cells are important in terms of flight risks.

@TimN23 This is a feature request, please open a new feature request from here with this idea. Closing this thread.

My friend, you're definitely owed a coffee.

My Pleasure @TimN23

Developing this takes a lot of my free time, and some late nights, but I enjoy it a lot :) working on something cool for the community is a rewarding feeling. You guys are so nice and supportive :)

It has already been implemented and tested, the exports will have this data too moving forward, just note that you need to re-import because the parsing logic has changed and we were not pulling this info to the database earlier. if you don't delete and re-import, this feature will not be available even after upgrading versions if you had existing data in the database. just syncing without deleting won't work either as it will skip all the files as duplicates.

can you please link me the drohnen-forum.de post? would love to have a look or even interact (can use translator)

Edit: I have a future plan to add like a warning feature based on simple data analysis (like sudden deviation etc) in the main dashboard which link to the actual flights. you can import and check back which flights has such issues and maybe save your drone from disaster.

Hi Arpan,
Today I installed 2.18.1 on MacOS.

First, I deleted all imported logs. Then I copied 25 new log files into the import directory and tried to find the voltage deviation or cell voltage value in the newly imported logs. Unfortunately, I couldn't find them.
Do you have any idea what I did wrong?

@TimN23 If you have reimported or synced them, they should be available. You are looking for them in the wrong place though.

Your image links above are mis-formatted as well

You will find the cell voltage plot in the telemetry panel under flights option, when you select a specific flight from the menu. Check the release page to find a screenshot.

You're right, I selected the wrong field.
Works well, an advantage could be a calculated maximum permissible deviation/cell, e.g., 0.4 V as an adjustable trigger warning.
It would also be nice if you could perform a user-defined sort in the Telemetry Panel, e.g., battery cells at the top.

I will test it for a few days and possibly write a feature request.

this is how same logs look at airdata com

@TimN23 I gave you the ultimate flexibility regarding the telemetry panel in the latest 2.19.0 version release, check it out :)

@TimN23 I did leave a comment there :)

But it says suspected "spambot" lol

Thank you so much for the support btw! I will put a public message on Ko-fi as well.

Hi Arpan, Nice to here. I'll check that out tonight, and I'm excited to see the options you've added for 2.19.
