Then place the {{fname|while}} under comment to disable it.
Proceed by placing a '''//''' in the front of the {{fname|while}} instruction.
When done, the code should look to this:
<syntaxhighlight lang="c">
void setup() {
Serial.begin(9600);
// wait until serial console is open, remove if not tethered to computer
// while (!Serial) { delay(1); }
...
}

Compile and upload the modified version to your Feather.
Great! You are ready. The program would now starts without waiting for the Serial Monitor.
== Plug the battery ==
It is now time to plug the Lipo in the appropriate connector.
When the Feather is plugged via USB:
* The Feather runs over the USB power.
* The LiPo battery is loaded from the USB.
When the Feather is unplugged from USB:
* The Feather is instantaneously powered from the LiPo battery.
* The LiPo battery is now discharging to power up the Feather.
The feather will run until the battery is discharged.
At best, the battery have 4.2V and discharge until 3.0V (when LiPo the protection circuit shutdown the power.
The time it takes to discharge depend on the power requirement of your LiPo.
If the LiPo can store 2500mAh and a project requiring 130mA to run will last after 2500mAh/130mA = 19 Hour of working.
{{ambox|text=This is an estimate. In real life, the current sink by the project is not constant so energy is not sink out constantly from the LiPo.}}
