I’ve had a simple system soak testing. Its not meant to be a deployable system, but I’m using it for testing out powering related algorithms.
It has an Xbee WiFi, LiIon 500mA, measuring MayflyVbat and ADS1115 extVbat. When the extVbat voltage is >=3.85V it will
and when below <3.85V only
I’ve used the 3.85 threshold as I found the Mayfly was resetting when the WiFi turned on and LiIon battery was around 3.7V.
For the “Solar Panel” I’ve got it connected to a power supply and simulating low sunlight conditions with a charge typically round 25mA.
