T-Motor VELOX V50A 3-6S BLHeli_32 4-in-1 ESC

The T-Motor VELOX V50A 3-6S 4-in-1 ESC is designed to control the speed of four brushless motors in FPV drones and multirotor aircraft. Instead of using four separate ESC boards, this integrated design combines all four motor channels into one compact unit, helping reduce wiring complexity and simplify drone assembly.

With a continuous current rating of 50A per motor channel and a peak rating of 55A, the VELOX V50A is suitable for high-performance FPV builds requiring reliable power delivery. It supports 3S–6S LiPo batteries and features upgraded QN3109 MOS components for improved electrical performance.

The redesigned cooling fin structure helps dissipate heat more efficiently, supporting stable operation during demanding flight conditions. Its 30.5×30.5mm mounting pattern makes it compatible with flight controller stacks using the same mounting standard.

How to Use

1. Check that your flight controller supports a compatible 4-in-1 ESC connection and mounting pattern.

2. Confirm that your battery configuration is within the supported 3S–6S LiPo range.

3. Mount the ESC securely using compatible M3 hardware and suitable vibration-damping washers.

4. Connect the four brushless motors to their corresponding motor output pads.

5. Connect the ESC to the flight controller using the appropriate wiring harness.

6. Connect the battery power cable with correct polarity and inspect all solder joints.

7. Configure the ESC and motor settings using compatible software and firmware tools.

8. Verify motor direction and perform a motor test without propellers installed before flight.

Important Notes

• The 50A rating is the continuous current rating per motor channel; the total current capability depends on operating conditions and cooling.

• The supported battery range is 3S–6S LiPo. Do not exceed the specified input voltage.

• Verify flight controller pinouts before connecting the wiring harness. Different boards may use different connector arrangements.

• Check battery polarity carefully before powering the ESC.

• Ensure adequate airflow and avoid excessive heat buildup during operation.

• Do not install propellers during initial motor testing or configuration.

• Use compatible firmware and configuration tools. Incorrect firmware flashing can damage the ESC.

• Always inspect solder joints, motor connections, and power wiring before flight.
