new to the forum and hoping this is the right place.
Building a project for my MSc dissertation, and for some reason the shield is only charging (or at least, showing a state of charge).
I’ve checked the battery voltage, it’s 3.7v. I’ve had it in the sun for absolute days with my 138x160 panel and now have it connected to a USB just to see if that will change its state. With a brand new battery, am I missing something?
The Seeed Solar Panel Shield Wiki Page tells me the battery is just low and not charging. But with days in the sun, do I have to drain the battery down for there to be any trigger or something.
