Simple ESC Matching Guide
Voltage (V):
ESC voltage = Battery voltage (e.g., 3S LiPo = 12V, 6S LiPo = 24V).
Current (A):
ESC current ≥ Motor max current + 20-30% safety margin.
Quick Examples:12V, 20A motor → 30A ESC (or higher).
Rule: ESC can handle higher amps than needed, but never lower. Always check motor specs!
