lipo

[squeeforever]

i have a e-maxx that i plan on running a lehner Xl3100 in and a warrior 9918. i would like to run lipos. only thing is i have no clue on how many i would need to get for optimum runtime and power. i at least need a 12-15 minute run time for long races. also would i need a ubec or whatever it is? or would i be better to run a reciever pack? and finally what would be the best charger to use? preferable one that can charge 2 at a time.

thanks
