Detail
The ESC has been upgraded to 55A with a heat sink. The PCB design has been improved by increasing the copper thickness from 2 to 3 ounces and enhancing MOSFET characteristics. Continuous current now reaches 220A across all channels, peaking at 280A for 10 seconds. The added aluminum alloy heat sink ensures efficient MOSFET heat dissipation for stable ESC output. It provides a true 55A output, prepared for your worst high-power 6S motors.
