Customize The OSD
In the OSD tab, you can choose which values you want to see on screen while you are flying. Enable and
disable individual elements using the Elements toggles on the left.
The Video Format section lets you choose whether your camera is NTSC or PAL. Betaflight defaults this
value to Auto, but Auto sometimes picks wrong. If this happens, you might not see any OSD text, or the
bottom o
f the OSD text might be off the bottom of the screen. In some cases, you won’t see any video
at all
—
just the OSD. Because of this, we recommend manually setting the Video Format to NTSC or PAL
depending on which type of FPV camera you have.
You can rearrange the individual OSD elements on screen by dragging them with your mouse.
Some individual OSD Elements of note are:
Main Batt Voltage:
This is probably the single most important element to use. Your battery must never
go below 3.3 volts per cell under any circumstances, or it will suffer damage. For a 3S battery, this would
be 3 times 3.3 = 9.9 volts. For a 4S battery, it would be 13.2 volts. Any time the battery goes below this
level, it is likely being damaged, at least a little. More importantly, you will have very little power and
may crash if you are doing aggressive maneuvers.
Although 3.3 volts is the recommended absolute minimum, you will get the best life out of your
batteries if you keep the voltage above about 3.5 volts per cell
—
10.5 volts for 3S and 14.0 volts for 4S. If
you are flying and you notice the battery going below this level, it might be time to land, or at least go
easier on the throttle. If your batteries consistently drop to this level when you try to fly, it might be
time to get new batteries.
When you are using the battery, its voltage will drop. This is referred to as “sag”. After you land, the
battery will recover a small amount and its voltage will rise. Our recommendation is that, the battery
should be at no less than 3.75 volts per cell
—
11.25 volts for a 3S and 15.0 volts for a 4S
—
after it has
been allowed to rest at the end of a flight. If your batteries are consistently resting at below this level at
the end of a day of flying, then you might be shortening their lifespan at least a little.
