...can't you use a diode or two to drop the voltage sufficiently, rather than a full blown regulator? It will be connected to a power source, so we're not really worried about efficiency.
Also, would this arrangement require a capacitor to smooth plug-in spikes, or should rechargebles be able a small amount of spiking? Or would there even be negligible spiking on plug-in?
Kiram & j_tetazoo, congrats on opening up a new area of hacking interest!
