shaunjohnson · 02.19.2009, 10:11 PM

some rough calculations show that a 4s vs 6s lipo under same conditions,
the 4s will have 1/3rd the runtime than the 6s will.
one example..
rEvo can get 30 mins on 5000mah 6s. (using average voltage)
that's 432w/h

so 4s (avg voltage) will require 3x the amps to reach the 432w/h of the 6s.

meaning that a 9000mah 4s will not last as long as a 5000mah 6s under same speed/running conditions.

but this is dependant on the load you imply on your vehicle.
