Has anyone ever used a Seeed Solar Shield with the Arduino? http://www.seeedstudio.com/depot/solar-charger-shield-v2-p-914.html?pages=2&r_q=q
My shield seems not to be charging the battery.
As shown in the figure, the fully charged battery remains at a constant voltage in direct sunlight during the day, drops during the night, then just stays at that voltage in sunlight again, not charging the battery. Is this normal? Shouldn’t it go back up to 4.2 V again?
There should be more than enough current to charge the battery while powering the circuit as the average current consumption of the circuit is around 70mA. The solar panel’s output is 158 mA in the shade and 500 mA in direct sunlight.
Is seems the shield is either powering from the solar panel, powering from the battery, but not charging the battery from solar while powering the circuit? But it should be, according do the wiki and description…
