@josecastillo Battery test, day 400: 2.4 volts. It’s low enough now that the extra power of beeping the buzzer on mode change causes a voltage drop to ~2.3, but it recovers to 2.4 over about ten seconds. New firmware is back up to 3.08 volts here on day 295! Both lines are red this time, but it’s the one on top.
