Battery Possibilities:

3.7V Li-ion or LiPo Battery

```
Capacity: 2000mAh or 5000mAh.
```

Voltage: 3.7V nominal (4.2V when fully charged).

Connection: Use a boost converter to step up the voltage to 5V if connecting to the 5V pin, or directly connect to the Vin pin if the boost converter outputs a higher voltage(e.g.,7-12V)

7.4V LiPo Battery

```
Capacity: 2000mAh or higher.
```

Voltage: 7.4V nominal (8.4V when fully charged).

Connection: Directly connect to the Vin pin.

18650 Li-ion Cells

Configuration: Use two 18650 cells in series to get 7.4V nominal.

Capacity: Each cell typically has a capacity of 2500mAh or higher.

Connection: Directly connect to the Vin pin.

Additional Infos: Deep sleep mode: https://randomnerdtutorials.com/esp8266-deep-sleep-with-arduino-ide/#:~:text=To%20put%20the%20ESP8266%20in%20deep%20sleep%2C%20you%20use%20ESP,connect%20RST%20to%20GPIO%2016.

"To put the ESP8266 in deep sleep mode, use ESP.deepSleep(uS) and pass as argument sleep time in microseconds. GPIO 16 must be connected to reset (RST) pin so the ESP8266 is able to wake up."

trigBoard has an extremely low power consuption.

If we use normal AA or AAA BAtteries we may need a regulator to lessen the voltage.

On the website above is a promising battery operation in their test 5 with three AAA batteries from Aldi Nord, a LDO, deep sleep and three DS18B20.
