Description

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 power to the video transmitter, along the whole discharge curve of the battery.

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.

 

I’ve tested quite a mouthful of modules of various sizes and specs, and thought I had found the best one at a time,

But it had its quirks and when I started noticing the quality going down over the batches I thought it was time to make my own.

 

I then went on to select the best-suited power IC for our specific 1S need and found this outstanding chip, boasting impressive specs that fit exactly our use case.

Then designed the circuit around it from the most reputable component manufacturers,

And out came this remarkably capable piece of gear that I can definitely trust to supply consistent, reliable power all the way through our 1S batteries.

 

Successor of the Boostyboi, the Boostybaby retains all of the performance in a now much smaller footprint, less than half the size and weight, at not even 0.4g!

Making it a viable option to add reliable video to any 1S digital or high power video build, from nano long range to tiny whoops.

 

It also retains the remote disable pad added in the BB Rev-02, 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 /ENI call it /EN for inverse enable; the IC enable pin is pulled up to VIN through a 100k resistor; it will always be enabled by default unless the pad is pulled low pad.

 

 

Why would you need one:

  • 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 lightweight of only 0.4g; fits most whoop builds and I’ve made it to fit perfectly between the wingman rear standoffs. (old pics of boostyboi for now 😅)
  • Built from top quality components from reputable manufacturers (Kemet, Samsung, TDK…) with high reliability in mind; rigorously tested to the limits.
  • High efficiency, low noise down to 2.5V and still useable way below
  • 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!
