KB1OIQ has discharge protection in his arduino controller:

If I add a terminal for controller power via VIN (https://olddocs.zerynth.com/latest/official/board.zerynth.doit_esp32/docs/index.html#power), I think voltage can be monitored. Can let user do the math on what voltage to not drop below, and enter that value into a field on the webform.

Quick search suggests that I would still need a voltage divider circuit (for a different board, but probably similar): https://forum.arduino.cc/t/monitoring-vin-on-a-esp32/894785/4
