LiFe cell = 3.7v fully charged vs Lipo cell = 4.2v fully charged- draw your speed comparisons from that info.
They do need balancing though- its just good practice + they come with balance taps attached anyway so...
The only real noticeable difference will be that you need a 2p setup to output the same amount of punch as a normal 1p lipo pack, hence people using 6s2p setups when Life/ A123 cells are envolved (comparable to a 5s lipo setup of the same mah (~4000-5000 25c)).
The biggest advantage really is the ability to charge them in ~15mins vs ~1hour for lipos, assuming you have a suitable charger..
