FT03 Charging Status Light

My FT03 charging status light is solid green when I plug it into the Type-C charging cable. Is this charging or not? I’m used to red when I see not charged, but this should be VERY close to not charged.

Probably not charging.
Im not sure whether it supports full spec USB-C or just USB A to C.

One important thing is it will not charge when the batteries are above 4V.

it’s finnicky. Now, it’s working.
