How it works

Robot rail and peak power budget

Sum subsystem output watts at their own rail voltages, then apply each conversion efficiency once. Estimate conservative battery current at the entered minimum battery voltage and assume all listed peaks occur together.

Battery W per row = quantity × rail V × rail A / conversion efficiency; battery current = total battery W / minimum battery V.
