Two-Way Bidirectional Brushed 5Ax2 PRO Dual-Channel ESC for 2-6S LiPo - Advanced Independent Motor Speed Controller for RC Tank and Speed-Difference Boat
The Two-Way Bidirectional Brushed 5Ax2 PRO Electronic Speed Controller is the upgraded variant in the dual-channel brushed ESC range, extending battery compatibility from the standard 2-3S to a wider 2-6S LiPo input. Each of the 2 independent channels delivers up to 5A continuous, driving separate left and right brushed motors simultaneously from a single controller board. The extended voltage range makes this PRO variant well-suited for higher-performance RC tanks, tracked platforms, and speed-difference boats where 4S, 5S, or 6S power packs are used to drive faster, more torque-demanding brushed motor configurations. Bidirectional operation on both channels enables full forward, reverse, and pivot-turn manoeuvres through standard 2-channel RC transmitter input without any supplementary controller hardware.
The PRO designation reflects refinements over the base model, including improved thermal headroom and more robust per-channel current handling suited to the higher cell-count voltage range. The speed-difference steering principle, where turning is achieved by varying relative motor speed or reversing one channel against the other, is fully supported by the independent channel architecture. An integrated BEC supplies regulated power to the RC receiver rail, consolidating the power circuit into a single compact PCB that fits neatly inside tank hulls and twin-motor boat enclosures. The PWM signal interface maintains straightforward compatibility with conventional RC receivers, keeping integration simple for builders upgrading from lower-voltage dual-ESC setups to a single-board PRO solution.
Key Features
- Dual-Channel Output: 2 independent motor channels, each rated at 5A continuous for simultaneous left and right brushed motor drive
- Extended Voltage Range: 2-6S LiPo (7.4V-22.2V) support for higher-performance tank and boat builds
- Bidirectional Control: Full forward and reverse operation on both channels for differential steering, pivot turns, and speed-difference manoeuvring
- PRO-Grade Thermal Management: Improved heat dissipation over the base model, sustaining reliable operation at higher cell-count voltages
- Speed-Difference Steering: Independent per-channel speed and direction control enables tank-style turning, spin turns, and gradual arc steering
- Integrated BEC: Regulated output powers the RC receiver rail without a separate voltage regulator
- Brushed Motor Compatibility: Designed for standard 2-wire brushed DC motors used in RC tanks and dual-motor watercraft
- Signal Input: Standard PWM compatible with conventional 2-channel RC transmitters and receivers
- Low-Voltage Protection: Configurable cutoff prevents LiPo over-discharge across 2S to 6S cell configurations
