I'm moving this from a post to a blog to keep people up to date with my progress.
For those who haven't been following the threads I've posted to here are the problems I'm trying to solve:
1) Battery charging- Make sure our batteries live long and prosper.
2) Equalizing- Make sure they discharge at an equal rate so you're range isn't limited by your weakest battery.
3) Cost- Keep the price lower than the alternatives.
4) Patents- Must do this all without violating patents.
