Default Does it matter?

what is better (hypothetically thinking), 2 25C 2S 6000mah in series or 2 25C 4S 3000mah in parallel. I understand they would have the same characteristics but was curious if one would perform better than the other

Well in series is going to give you twice the voltage so there it is. Double the voltage will make a bigger differrence than the C or the mah, but it sounds like you are getting ready to fry some electronics. Are you sure you are ready for that? The other thing is what are you looking for when you say performance? If you want it to run twice as long then go for the parallel wiring.

Voltage and runtime is the same with these two set-ups.

Wouldn't they be the same voltage of 14.8v?

Mathematicly C rating total and mah and voltage will all be the same, but i would think the 2 x 2S 6000mah packs would be better and more relaible as there is a total of 4 cells in the car (less conections and less to go wrong)

As with the other configuration there is a total of 8 cells in the car.

Cheers

2s verses 4s ok. I missed that the first time.

Generally C rating refers to the pack. If you put two 25 C rated packs in parallel you have assembled a 50 C pack. The series packs would only be 25C. If you are doing a speed record run at very high amps (250 or so amps) or you have the packs in a powerfull airplane this may make a difference. If not you will notice little difference.
