They have sufficient voltage: 3.3v*4= 13.2v, which is greater than a 12v gel cell, so you'll get greater RPMs than with a 12v. Additionally, you get higher discharge rates (in AMPERES) with LiFe than both lipo and gel cell. Then there's the safety aspect. 12v gel batteries are acidic and lipos will BBQ your box if you run them all the way down. With a LiFe pack, you get the best of both worlds.
