Suddenly wrong voltage

[DUKE40]

Hi,

Last week i went flying and everything was fine.
Today i wanted to start and the AQ is always reporting a voltage of around 9.4V for All my charged 3S lipos.

I checked the lipos they all have definitively 12.6V.

What can be the reason for this behaviour? FW is the right rev.

Hi,

I have the same problem. I use a 4s Lipo with 16,8V and the voltage displayed (Ground Station) is 14.2 V The board should be r1, becauseI bought it 2 weeks ago.

Thanks in advance!

Hi,

anybody an idea what I need to check?
Currently I am unable to fly due to this issue and I really would like to get my Quad back in the air.

Which FW and QGC version are you guys using? AIMU or DIMU?

I am using r403 from Menno for Rev1 Board, I did not check in QGC up to now, it was on the HoTT Telemetry.
I will check with QGC, but I do not expect anything different. Checked QGC shows 7.9V my lipo-checker simultaneously attached shows 11.47V so quite a discrepancy.
QGC is v1.5 Alpha 6 self compiled, as I work on Linux.
I am using DIMU.
And as already mentioned, everything was fine a few flights, and when I wanted to fly again last week suddenly the HoTT telemetry showed a much lower voltage than the current voltage of my accus.

please check your voltage by multimeter
maybe your connections going wrong (patine, rust, wrong solder or sth)
