Looks like a really good idea - do you have a graph yet?
I love the idea of controlling the current draw by varying the voltage on the FET.
I'd actually really like to do an Espruino battery charger/conditioner - it'd be great to have something that'd keep my NiCd electric drill batteries in a good condition. It could even do cool things like cycle them while always making sure that one of them was fully charged :)
