It's all about amps and watts.
Bullets can handle more current, but for the same power, you pull half the amps on 4S that you do on 2S. It's much easier to spec a power system that can use common XT series connectors on a 4S setup than on a 2S or 3S one. Plus you can get anti-spark XT connectors (which is more important for higher voltage, there's a higher spark risk on 4S than on 2S)
I'm a little surprised I don't see XT150's yet in use, some of the high-amp plane & heli guys are going there for the crazy high current capability and anti-spark, which is even more important on 10S and 12S power systems.
As a plane guy coming into the surface world, I'm really surprised by the low voltage/high amp power systems that are so popular for surface use, it really stresses packs & ESC's for a given wattage.
