Yet another E-revo lipo question

[Traxxas Addict]

Sorry, I run the 3S in my G3R (Gorrillamax) where I don't worry about batt sizes. I also have the 2S hard case 35C units and they are also excellent.

yeah Traxxas really was a bit shortsighted on the size of the battery compartments. if you want to run 6S you have a 5000 limit on batt size using the zippy H 3S 20C's although I am waiting on the new 30C 3S zippys which look like they will also fit.

I am also hearing that the new SMC 2S 9000 28Cs will fit. these could be the best yet in terms of run time and punch.

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.

If you are looking for other enerland cell options:

3700 25c fp/polyquest 4s packs will fit in the erevo trays with the leaf spring removed, parallel them up for 7400 4s lipo.

4500 3s 30c polyquest will fit in there too, in series for 4500 6s.

5s will be best with that motor. If you want to run 6s a lower kv motor will allow for more battery choice, such as a 5000 20c pack. Something like a 1600kv motor will work great with not quite top end lipos.
