If it doesn’t (or can’t) show up in firmware, there are external solutions that can accomplish this — for example the Buddipole PowerMini. I keep one in-line, even without a solar panel connected for just this purpose. It will both alarm and disconnect the external battery when it reaches a preset low voltage.
