Wow, it seems like the same question is just getting bounced around here.

A zippy lipo is not much different from any other chinese lipo. If you can correctly estimate the wattage output of your setup you will able to accurately pick a lipo that will work.

Hpi includes the 25t pinion to be used with phatline tires to get the advertised 62mph. No other reason than that.

Getting 40mph out of a MT like the flux with 4s is not the easiest thing for a batt. Getting the same mph out of a 6s setup will pace less load on the batt. The gearing will be lower, the output of the motor will be the same (same top speed) and the voltage will be 50% more... So the amp draw will be considerably lower. So while you need a 4s lipo capable of 130-150 amps cont, you can get away with a 100-120 amp cont capable 6s lipo.

This is pretty basic stuff, if you cannot get a grasp on this you may need to go back to nitro or nikko...
