I'm working on a model kit and embedded an LED inside it for cool glowing effects. I usually plug batteries in, but decided it would be cool to use a solar panel instead, so I bought 2 of the really cheap solar LED flashlights.
Got it open a-ok, the circuit is simple. Diode to prevent back current, 3 LEDs in series, and a momentary switch.
The only problem was that I couldn't find a datasheet for the cell (a QFsolar 3722-9L) so I grabbed a multimeter to take readings so I didn't fry anything. I get a max of around 7V, but the current seems odd to me. I can only seem to get .1mA flowing out. I've never done anything with solar cells before, is this typical?
