Battery watch: feature request #232

One more item for the wishlist: Show TTGO battery voltage in red and/or blinking on TFT display when below some threshold.

This is good. I was actually wondering if the TTGO switches itself off or what happens. It doesn't have overdischarge protection so it can still harm the lipos.

Depends on the model. The T-Beam (or any model with AXP192) should have low power protection. The other models do not have such protection, usually battery goes directly (usually via a diode) to the 3.3V regulator.

That's correct. This is why I also wanted to display the voltage on the OLED screen so I can try and prevent over-discharging... I've only let it slip once by accident yet.
