Hi everyone,
I'm working on a simple solar charger for a bicycle light. Something that I'm stuck on is the relationship between solar panel voltage, battery voltage, and charging.
I have a circuit that consists of a 3V panel, BAT41 diode for reverse current blocking, and two 1.2V NiMH AAAs in series.
If my panel is at 3V and the diode drops it (by ~0.6V, I believe), will the batteries ever be able to fully charge? If not, is it safe to put two 3V panels in series and charge @ 6v?
Thanks,
