if i was just using the heatermeter as a thermometer and have no fans how long do you think this would last?
Simple math says you should get about ~15 hrs if you run the battery flat and the voltage stays close to 12V till the end.
Heatermeter without a 12V load will consume about 250ma at 12V with a Wifi dongle installed and backlight set at 100%.
(You can reduce by 40 or 50ma by turning off backlight off or setting at 10%)
Battery rated at 3800mah @ 12V.
3800/250=15.2
