sorry, i know questions like these have been asked before

trakpower do saddles in 3200 and 4800 mah
3200 will power a 4x4 buggy for 5 mins, the way the cell delivers its power give you a longer run time from a lower capacity

But you are right in that the saddle lipos aren't as high capacity as the long brick lipos.
Frankly, saddle pack chassis configurations are designed around heavy (NiMH) batteries and assume that the heaviest(most massive, to be precise) component is the battery pack. They aren't as lipo-friendly as the 6-cell inline chassis in some ways.

4800 sadlle to 4900 stick??

I think a better way to put it would be it does not loose performance though its lifespan.

the site says
100+ race-worthy cycles, 200+ for practice.
see the 100 plus? that means there saying you can get a minimum on 100 cycles NOT a max!

the 100+ life span is on trakpowers site trakpower put this as they were going by the plane/helicopter boys who fully charge a pack and fully discharge the pack in one flight, this is also discharged at max power (one cycle is a full charge from 6 volt then a full discharge)
they did not realize how the car world works where we top them up run for 5 mins and re top up. so you may get "3 car cycles to equal a full cycle, we are also not on full power the whole 5 mins, so the cell goes through less strain.
i can assure you that you will get far more than 100 cycles per pack and 100% at 100 cycles they will not fail just like that, the capacity will simply fall off, the voltage will remain
as tom has said he had a pack off me for trial along with chris long, toms was near 100 cycles old, chris's was nearly new, niether could tell the difference in power and run time.
heres one for you all,
3200 saddle £45 use one pack all day, IF you get YOUR claimed 100 cycles thats 0.045pence per cycle and 16 meetings with 4 qualifiers and two finals, with very little loss in power
can you do that on ONE set of nimh (£45 worth max value) and not notice a drop in performance?
