I looked on the web, and for some reason there is conflicting info. From 1.2 volts to 4.2????
I'm asking about ONE Cell only.
The reason is because I have a solar panel that was used for a Li-Ion battery powered solar light. The batteries are trash, but the solar panel is working. I'm sure I can find other uses for it. It's about
5x6 inches, so it should put out something useful.Thanks
