What happens when the MFO.BO.02 battery drains completely?
The battery will shut off if it is close to empty. Once the battery builds up a bit of a buffer of power and is partially charged (about five minutes of good sun), it will turn itself on again.
The battery will also shut off if a “fault” occurs. The most common are short circuits, over discharge, over temperature and under temperature. When the fault is resolved, the battery will resume normal operation.
