What is the amp hour rating for running the PTLevel WiFi for 24 hours?

You may want to run the PTLevel WiFi on a solar system but how big of a system do you need to setup?

Currently the PTLevel WiFi draws a constant current of 85mA and so for 24 hours, it would be a 2.55 amp hour requirement. This number takes into account not to fully discharge the battery.
