Notes on Adafruit Lipo Charger
Currently being used on the AH6
During the winter there is little light to power the solar panel and so the battery is used to power the node. The onboard LEDs continue to be powered even when the battery voltage is unable to sustain the node.
The LEDs will drain the battery beyond the safe voltage (due to the low but persistant current draw it'll work even though the LiPo has protective circuitry).
