120A 3-8S 4-in-1 ESC for FPV Drones, 30.5x30.5mm

A 120A 4-in-1 ESC on the standard 30.5x30.5mm stack pattern for high-power 3S to 8S builds — heavy long-range quads, cinelifters and hard-hitting freestyle machines on large motors. An onboard current sensor feeds live current draw to the flight controller for OSD readouts and mAh tracking.

Key features

• 120A continuous, 130A peak: headroom for big-stator motors and sustained high-throttle flying.
• 3S–8S LiPo input: covers mid-voltage freestyle builds through to 8S long-range and lifting setups.
• Integrated current sensor: current ratio of 120 for accurate real-time monitoring and telemetry on a supported flight controller.
• Analogue and digital throttle protocols: works with current flight controllers and firmware.
• 4-in-1 layout: four ESC channels on one board save weight and wiring compared with separate ESCs.

Specifications

• Continuous current: 120A
• Peak current: 130A
• Input voltage: 3S–8S LiPo (11.1–29.6V nominal)
• Current sensor: onboard, ratio 120
• Mounting: 30.5x30.5mm, 4mm holes
• In the box: 1 x 120A 4-in-1 ESC

The ESC ships as the board alone, so plan for a low-ESR capacitor across the battery pads and a battery lead to suit your packs. At 8S, confirm your flight controller accepts full battery voltage before connecting it to the ESC harness.
