The draws are typical averages over a run, not peaks. Launches and wheelies pull several times more for a moment. Runtime = 6.5 Ah x 0.8 usable / average amps x 60. Try your own figures in the LiPo runtime calculator.

Frequently asked questions
How long does a 6500mAh battery last in an RC car?
At 4S it depends almost entirely on average current draw. 1/10 crawler, trail pace: about 45 minutes; 1/10 4x4 brushless bashing: about 7 minutes; 1/8 4x4 bashing: about 7 minutes; Wide open speed runs: about 4 minutes. These use 80 percent of the rated capacity, which is the safe depth of discharge for LiPo packs. Bigger tires, taller gearing and grass all raise the draw and shorten runtime.
What C rating do I need for a 6500mAh 4S pack?
Maximum continuous current is capacity in amp hours times C. At 6500mAh a 50C pack is rated for about 325 A and a 100C pack for 650 A. Real draw in most cars is far lower, so a quality 50C pack is plenty for 1/10 bashing; the higher rating mostly means less voltage sag and a cooler pack.
