The LiPo battery is 3S, which means +11,1 nominal volts (100% charged = +12,6 volts). As shown in the links posted within this task, the Arduino Uno has an operating voltage of +5 volts, but, thanks to its voltage regulator, I can give from 7 up to 12 volts.
I could charge the battery until 12,0 volts and then just connect the battery and the Arduino together, however, even though it is allowed by the manufacturer, this solution will heat the voltage regulator! Also, this solution would underuse the battery.
I could use an UBEC to step this voltage down, but I only have one and I intend to use it later.
I am thinking about designing some voltage divider and integrate everything on a breadboard… This will allow me to integrate some on-off switch.
What you guys think about this idea??
