No, I have not a schematic. But look at the PDF for the L200 at

http://us.st.com/stonline/books/pdf/docs/1318.pdf (about 165KB)

and there at figure 1 in these data sheet. The L200 is an ajustable
voltage and current regulator from ST Microelectronis (http://www.st.com).
So you can EASY (!) built a programmable voltage regulator with current
limiting with this IC. The IC with only 3 resistors and 2 capacitors and
you have a gel-cell charger.
