The warning is fairly standard, and comes with any and all battery operated devices. It’s just the manufacturer covering their bases, because while the hardware should be safe for continuous charging, the IC might get damaged by a surge and cause a fire, in which case GL.inet can just say “sorry man, we told you not to leave it on the charger”.

Precisely. The charging IC should be protection enough in the Mudi, and Li-Ion batteries today are not as fragile as they were ~10 years ago. The chances of a fire are low, but not non-existent.

In fact, the charging IC should work in a way that while charging, the battery acts as a backup/UPS unit.

In fact, if it’s possible to turn the charging function on and off, I’d love to have that tied to the switch on the Mudi - it would make a lot of sense, you pick it up, and with a click enable charging the battery, or disable it.
