A123 cells are physically more robust than Lipo, but they are heavier than Lipo. You can charge A123 faster than Lipo, and A123 is usually less expensive.
I haven't tried the graphite diff housings, but they would flex more than the aluminum, and generally wouldn't be as strong. Graphite is lighter than aluminum, though.
