Hello
Looking to buy new batteries 7.4v 2s
Big difference in price between 80c 5000mah and 80c 7200mah.
I understand the longevity of the run will be much longer with the 7200mah but I'm running stock 17.5 touring and usgt so 6 minute max.
Will the higher mah also give more punch or is that just based on the c rating. I'm comparing the same brand too!

Its all about the amp rating. If the esc wants the amps will the lipo provide it.
For example a 5000 mAh (5.0 Ah) battery rated at 80C should be able to deliver 5.0 x 80 = 440 Amps
For example a 7200 mAh (7.2 Ah) battery rated at 80C should be able to deliver 7.2 x 80 = 576 Amps
Is 80c continuous or burst C rating? For the formula you need continuous.
If you esc does not require the amps the only benefit is longer run times.

All else being equal the larger pack should maintain voltage under load a touch better and thus provide a little more punch electrically speaking. Yes even at low amp loads like a 17.5T.
But, it likely is heavier too, which can hurt overall performance more than a slightly better voltage. Especially if the car can't achieve minimum weight with the larger pack.
