Nice! Now all you need to do is get rid of that pesky copper and get better FETs.
Better FETs are coming all the time... It's amazing what the FET manufacturers are doing...
Just three years ago, the best FET available at 60V in an SMT package was about 6 milliohms -- today it's about 3 milliohms. By this time next year, we are hoping to be at 2 milliohms. Awesome stuff happening in the FET world.
