Radically extend your flight time and improve your video reliability on 1S Li-ion builds with this 5V voltage booster
One of the major challenges with digital or longer-range 1S builds is supplying enough voltage to the video transmitter, along the whole discharge curve of the battery.
Checkout our BEC/PDB section and our Fractal Engineering Products!
In most cases, Li-po batteries can be discharged down to 3.5 or even 3.3v.
That is already edging the limit of the HDZero Whoop Lite VTX (which tends to completely brownout below 2.8V and will not restart unless power-cycled)
But even more so on Li-ion builds whose batteries can be discharged down to 2.5v – All while showing higher voltage sag under load, which can turn off your video under the slightest punchout past mid-battery capacity
That is why I use a voltage booster on my digital and discrete analog VTX Wingman BNF builds.
This is a remarkably capable piece of gear that you can definitely trust to supply consistent, reliable power all the way through our 1S batteries.
For this new Rev-02 I have also added a remote disable pad, allowing you to switch off the output from the FC when pulled to ground.
That will allow you to turn off the connected VTX remotely, from your radio, whether be it to save battery, cool it down or simply reboot it in the event it got wonky
To use it, I suggest remapping vtx power resource in Quicksilver to your Buzzer pad, and wire it to the /EN pad.
Why do you need one:
- It will boost its input voltage from as low as 1.8v to 5V, 2.1A.
- It will power your HDZero Whoop lite or Walksnail VTX all the way down to 2.5V and below, even at full output power.
Small package and light weight of only 1.3g; fits most whoop builds and I’ve made it to fit perfectly between the wingman rear standoffs.
Built from top quality components from reputable manufacturers (Kemet, Samsung, TDK…) with high reliability in mind; rigorously tested to the limits.
Added in Rev-02, a remote disable pad to turn on/off your vtx from the FC to save power or reboot the VTX
It is in my experience a vital element in building a reliable 18650 1S build, whether be it with a digital or a high-power analog VTX
Entirely removing the video brownout bottleneck and enabling you to experience flights upwards of 20 minutes on a digital Wingman!
