@cos There was discussions about doing higher undervoltage limits because if the voltage is falling fast, the deep sleep state may not reached before undervoltage let the bits get corrupted in the esp32 With your very little battery this can be the case. On my old v2 with 2200mAh it do deepsleep. None of the lora boards do have proper hardware battery (undervoltage protection) menagement, they all do have charging controllers only. The lipo bms build into the battery switch off at 2.5v which is to low to be in a safe state of the esp 32.
