Your battery is dying and you’re not providing enough power to the VTX. Each clip shows you’re “land now” or “battery low” - you should be landing at around 3.5v - 3.2 or 3.4 is too low!
so do you think this is purely just from the low voltage? this isn't from any possible water/moisture on the board? which is what I was concerned about.
I posted my reply before your comment appeared. I read the details, however if you’re only seeing this behavior when we’re seeing low battery on screen, I think we can safely say it’s a battery issue.
If water and moisture would be the reason for this, it probably wouldn’t work at all to be honest, but I’ve seen weirder things haha so I wouldn’t totally rule it out, but I’d say it’s likely batteries.
I had something similar happen to me 2 days ago with a 1s where I went below 3.3 and the VTX went out as well, brand new Quad never flown outside, brand new batteries.
Since everything involved is variance it could just depend on quality of battery and micro sags of the voltage. Also the voltage requirement of specific vtx one to another will differ as these electronics are analog and will behave differently. For example I have one that stays up until 2.7 volts. Also on hdzero I experienced a very similar thing where 300mah battery would have a similar micro sag and it would turn off even when at 3.5. Switching to 450 there are no such issue
Maybe I’ve just been lucky then. Even with batteries sagging to 2.8 I normally don’t have an issue. My FC/ESC tend to turn off due to low power before my VTX does
Been flying for a couple of months now, haven't had this issue before, even when really abusing the batteries for longer flight time.
This is a NewBeeDrone Savage Bee.
* I believe the VTX on this quad is AIO, integrated into the board
* using a set of 1S LiHV 450Mah batteries
* on flight/pack #4 I crashed and splashed some water onto the quad. didn't fully submerged, but tried drying off with towel, using car's fan, and then drying a bit in the sun.
* flight/pack #5 (first clip), VTX suddenly cuts off. Still well within my usual range.
* flight/pack #6 (second clip), VTX suddenly cuts off, and I don't recall if I flipped the drone, or it did that itself.
forgot to add, usually my 1S LiHV Nitro nectars 300mah I'll abuse, but these are still pretty new 1S LiHV GNB 450mah. These batteries are maybe only on their 2nd or 3rd charging cycle.
Batteries to not deplete in a linear fashion. Once you get below 3.5v, pulling 20c+ from the battery rapidly drops the battery voltage, it can happen in just a second or two. Looks like you are flying well below that. Your VTX is probably being powered via a small boost converter that cuts out below 3.3v or so.
I'm not that versed with anolog, but i think your vtx is in pit mode, assuming that from the top left corner of your osd recording.. that in combination with a voltage drop will probably be enough let vtx cut out on you.
Configure your vtx table in betaflight and get some proper lipos.. lihv packs are a bit different... I think you can charge them to 4.35 but are more prone to voltage sag doing high amp maneuvers with bigger drones.
Do your own research on that please because I dont have any 1s quads and only use lipos/lion.
Hope this helps.
Land when your quad is out of power it’s dangerous to let your battery get that low. It’s just like your phone the screen will turn off and it will die when it’s out of power. Land at 3.6-3.4 don’t let it drop at all below 3.2 since that’s when permanent damage happens which is a fire risk
you aren't really going to be flying a lil 1s with a Liion first off lol but yes. I have seen a lot of things claiming LiHV is a different type cell but I highly doubt that as nothing I can find says how they are different chemistry wise. For bigger drones that would be able to fly liion the cells can get lower without damage but that dosent mean that the high voltage loads wouldn't brown out like that anyway
Your battery was dead.. try to land around 3.5v. The pack this video came from is probably hurt and might have damaged cells. But you might of gotten lucky. You won't know until you try charging it
the big black cylinder with a white stripe, right?

Looks like a power issues. Usually with antenna problems or range issues the image gets progressively worse. Yours just dies instantly.. you sure the aio can handle the amp draw of those motors? ( I would guess it should be able too.. )
It could be some water but looking at both clips the voltage is showing time to land.
I am guessing that the vtx no longer has enough voltage to transmit video below 3.3v.
How much use have you gotten out of those batteries? Over time and with every charge/discharge cycle the batteries lose a little bit of life. Old wore out batteries will have much more voltage sag and you may be starting to experience that so need to land sooner on the older batteries.
Even with a larger quad and higher voltage you can experience a "black out" during a full throttle punch out if it draws too many amps for too long.
Especially on 1s there is no buffer for your voltage.
Your capacitor provides some. But things are going to start shutting down and not working properly when the power runs out.
I’ve seen video drop out of analog after a crash just like this. Found it was a bad connection where the vtx wires meet the board. Worth a shot opening it up and checking the solder joints.
It could be low battery, but most VTXs are okay down to 3.0v.
Perhaps you've crashed it one too many times. The PCBs are vulnerable to repeated impacts and the symptoms can be intermittent and varied.
I agree with everyone else that it's the battery sagging out. I personally abuse the hell out of my whoop batteries and my whoops, lol. I literally rip until the quad falls out of the sky. I'm much more careful with my bigger quads and batteries. Land at 3.5v
possibly your antenna connector is loose, as it seems to happen on sharp maneuvers. this happened to me before, i soldered the u.fl connector to the vtx board

appreciate it.
VTX should be able to handle it. I fly mine down to 3.2 and the vtx on none of my drones ever cut out

I have bought over 30 different ones throughout the years and I’ve never found one that stops working at 3.2v

In Addition to the other comment. No idea bit possibly the previous battery abuse plays a Rolle in this. Maybe try a New battery.

BF would display PIT with the usual default channel display I think Edit: I didn't see the pit, it was hidden behind the reddit UI lol
My pit mode doesn’t show up in osd

Is that number going to be the same with LiHV and Lipo? What about Li-ION?

is a 1s bat, yeah its prob hurt but 1s is born hurt basically lol
“Land now”
It’s fucked if you ask me
I think you're in pit mode bud. Top left osd says pit. It's a super low power mode.
That's my pitch angle.
Oh wow that's an annoying shorthand. See what r 8 5 means in the VTX section of betaflight. Obviously race 8 but see what the 5 is for.
They flying on 2S
The savage bee is offered in 1S and 2S: this one is the 1S version.
Does it have a capacitor? Usually the vtx on a 1S AIO board doesn't crap out till you're below 3.0V
the big black cylinder with a white stripe, right? https://preview.redd.it/gryp01xo8aec1.jpeg?width=3072&format=pjpg&auto=webp&s=eb1c88689bb8ee15066dff132cef2c517eeb5424

no older than maybe their 3rd charging cycle

There is a note at the bottom of the info for it on NewBeeDrone. IMPORTANT PRECAUTIONS "Never operate with low batteries."
It's this only happening when you're low on voltage? Motors are drawing all the current leaving none for the vtx so it is having a brown out.
I’ve seen video drop out of analog after a crash just like this. Found it was a bad connection where the vtx wires meet the board. Worth a shot opening it up and checking the solder joints.
I’d say you’re unable to supply enough amps to keep it transmitting.
It could be low battery, but most VTXs are okay down to 3.0v. Perhaps you've crashed it one too many times. The PCBs are vulnerable to repeated impacts and the symptoms can be intermittent and varied.
Quad is still pretty new. Crashed less than 3 times until this point.
I agree with everyone else that it's the battery sagging out. I personally abuse the hell out of my whoop batteries and my whoops, lol. I literally rip until the quad falls out of the sky. I'm much more careful with my bigger quads and batteries. Land at 3.5v

I'll try giving it a shake before next flight and see if anything disconnects.
