Mine uses an 18650 and a little 5v boost chip like the ones in the charger packs. I added a bit to the program to read the battery voltage so I know when I need to recharge. With the chip, a little logic, and transistor it also shuts down before battery is drained to low. It has a mini usb for simple charging. Works great.Battery-operation is indeed a requirement.
I'm looking into using the 18650 battery as well, including a charging option. With the recent live aboard disasters in mind, such a simple analyzer could be a personal CO detector as well. E.g. adding a buzzer that sounds when the CO level goes above a certain value.
At the same time, that battery should never become the cause of a possible fire....
