Two-Way Bidirectional 10Ax2 Dual-Channel ESC for 2-6S LiPo - High-Current Independent Motor Speed Controller for RC Tank and Speed-Difference Boat
The Two-Way Bidirectional 10Ax2 Electronic Speed Controller is a high-current dual-channel brushed speed controller built for RC tanks, tracked platforms, and speed-difference boats that demand more sustained motor drive current than standard 5A-per-channel units can reliably deliver. Each of the 2 independent channels is rated at 10A continuous, providing a total output capacity of 20A across both motor channels simultaneously from a single compact controller board. Combined with a wide 2-6S LiPo input range covering 7.4V through 22.2V, this ESC accommodates everything from entry-level 2S tank builds through to high-torque 6S tracked and marine platforms where heavier brushed motors, larger track assemblies, or bigger hull displacements place significantly greater current demands on the drive system.
Bidirectional operation on both channels enables full forward, reverse, and pivot-turn manoeuvring through standard 2-channel RC transmitter input, with speed-difference steering achieved by varying the relative output speed or reversing one channel against the other. The step up from 5A to 10A per channel makes this unit well-suited for medium-to-large scale RC tanks with higher-KV or lower-resistance brushed motors, twin-motor boats running larger propeller diameters, and custom skid-steer robotics platforms where motor stall currents routinely exceed the headroom of lower-rated dual-channel ESCs. The single-board layout consolidates both drive channels, signal processing, and receiver power into one unit, simplifying wiring and reducing installation complexity inside tight hulls and chassis enclosures.
Key Features
- Dual-Channel High-Current Output: 2 independent motor channels, each rated at 10A continuous for a total drive capacity of 20A
- Extended Voltage Range: 2-6S LiPo (7.4V-22.2V) for compatibility across entry-level and high-performance tank and boat builds
- Bidirectional Control: Full forward and reverse on both channels for differential steering, pivot turns, and speed-difference manoeuvring
- Speed-Difference Steering: Independent per-channel speed and direction control enables tank-style turning, spin turns, and arc steering
- Higher-Current Headroom: 10A-per-channel rating handles heavier brushed motors, larger track assemblies, and bigger propeller loads versus 5A-class dual-channel ESCs
- Brushed Motor Compatibility: Designed for standard 2-wire brushed DC motors used in RC tanks and dual-motor watercraft
- Signal Input: Standard PWM (1-2 ms pulse width) compatible with conventional 2-channel RC transmitters and receivers
- Integrated BEC: Regulated 5V output powers the RC receiver rail without a separate voltage regulator module
- Low-Voltage Protection: Configurable per-cell cutoff prevents LiPo over-discharge across 2S to 6S configurations
- Thermal Shutdown: Automatic over-temperature protection on both channels under sustained high-load and high-current operation
- Compact Single-Board Design: Low-profile PCB consolidates dual-channel drive and receiver power into a single unit for clean hull and chassis installation
Applications
- Medium-to-large scale RC tanks and tracked vehicles with higher-current brushed motor requirements
