How to estimate power draw

Average power draw depends on your motor, gearing, and driving style. Casual bashing: 200–400W. Aggressive bashing: 500–1000W. Racing or high-speed runs: 1000W+. Check your ESC's watt logging if available, or use a watt meter at the battery leads.

Tips for longer runtime

Use a higher capacity battery, gear taller (lower FDR) for less motor load, or drive at partial throttle. LiPo batteries should not be discharged below 3.5V per cell to preserve longevity.
