Hi,
I want to charge a small Li-Ion Battery taken from an old iPod (3.7V, from 4G iPod), it should be charged from the generator on my bicycle, i.e. the source would be intermittent and not of a constant voltage.
The battery itself (Model no. 616-0198) has three cable coming out, black,red and white. What is the white cable used for?
Could you point me to a good charging circuit for this application?
Thanks!
