Great catch there Wiffles and an excellent question.
I am swapping the PDB XT60 with the XPW. It has a true sensor. Right now the FC is using some funky algorithm to calculation since I'm feeding the FC power via the J11 5v pin. It's obviously not perfect but it's close enough for freestyle flying, coupled with a timer.
It's not sexy but it works until I swap the PDB xt out for the XPW.
I reason I mention it is I used the Omnibus on my last build and made the mistake of powering the FC with the 12v BEC. When I took it out to fly I started to wonder why my OSD always indicated 11.8v :|
Interesting. Mine moves/depletes. I'm almost certain, but I don't watch it like a hawk as I'm too busy trying to avoid cutting my own head off.
I'll pay really close attention tomorrow. Also, I'll alter the build the moment I swap out PDB's. I do t want to confuse anyone or give them unreasonable expectations.
Well if you're feeding the true battery voltage to the board then you'll get an accurate reading, but if you filter the battery it'll stay at the voltage the BEC assigns it to.
True but there were reports of the FC getting really hot on VBat. Accurate OSD was less important to me than potentially cooking something on my first scratch build.
Don't get me wrong. I appreciate and am grateful for your advice. And I will resolve the issue shortly. Just explaining why I made the decisions that I did.
You powered the FC via the 5v BEC, but what about the vbat for monitoring the voltage?

Thanks for asking!

No problem, I just wanted to share my experience and mistake concerning this board :)
It's truly welcomed!
I have so much to learn.
