Quite much...
But not as much as the 150C 8000mAh 28.8V pack that goes into my friend's electric Baja. That battery is monstrous.
On topic, if you can fit a "large" type battery, a 8.4v will spin it no problem.
It's not the voltage that is the problem here, it's current. Especially with high-torque motors.
With that said, 7.4V 2000mAh 25C should pull your spring no problem. If not, redo your mechbox work, there is something wrong.
