I'll guess your current setup is good for 20-24 minutes. My buggy seems to need about 5500mah for a 30 min race under ideal conditions, and a bit more depending on the track and my driving habits. I would be confident with anything 6000mah+

No doubt that 8000mah is enough even for a hard drivng style with your setup.

I'm intersted to see what you find for runtime for your setup today...
