Calculate optimal battery specifications power requirements discharge rates runtimes safely.
The calculations within this tool rely on fundamental electrical engineering equations tailored for high-drain robotic applications:
Input your nominal battery voltage, capacity in mAh, and continuous C-rating into the first section. In the middle section, specify your motor counts and current draws under both average and peak loads. Define your arena match duration and desired safety margin in the final column. Hit calculate to review immediate feasibility, current thresholds, and runtime safety assessments.
Designing a reliable electrical system for combat robotics requires balancing weight, voltage, and current draw. LiPo and LiFePO4 chemistry batteries dominate the sport due to their high discharge rates and energy density. However, pushing these power cells past their thermal and electrical limits can result in catastrophic failure, fire, or sudden power loss mid-match.
When selecting a battery pack, builders must account for weapon spin-up surges and drive motor stall currents. Stalls draw significantly higher current than running loads, which quickly sags battery voltage if the C-rating is inadequate. Incorporating a robust safety margin ensures your robot maintains competitive performance throughout the entire duration of the combat bout.
