Battery runtime estimator
For older students: estimate safe runtime. Use measured current when possible.
Estimated safe runtime: about 68 minutes. Real robots vary by motor load and battery health.
Estimate = capacity ÷ average current × 60 × 0.75. The 75% usable-capacity factor is a classroom assumption, not a battery protection limit. Actual runtime depends on discharge behavior, cutoff voltage, and load.
