How it works

ESC and shared battery-path ratings

Check actual per-channel ESC continuous current, event current and permitted duration, together with the battery operating voltage. Sum channels on a common battery path and compare its documented continuous allowance against both steady and peak demand.

Common-path current = channel count × per-channel battery-input current + other battery current. ESC event duration matters when event current exceeds continuous allowance.
