Bidirectional Brushless ESC with ultra-precise current control (20A-60A options) for seamless motor reversal in RC applications. Aerospace-grade aluminum alloy housing ensures heat dissipation and durability in extreme conditions. Waterproof silicone coating protects internal circuitry from moisture, ideal for marine and underwater propulsion systems. Supports high-torque brushless motors with customizable acceleration curves via programming card (included). Compatible with drones, wind-powered boats, and submersible ROVs. Gold-plated connectors minimize resistance for maximum power transfer. Built-in BEC circuit powers auxiliary devices without extra battery. Thermal overload protection automatically safeguards components during prolonged heavy loads. Plug-and-play installation with color-coded wiring for foolproof setup. Precision CNC-machined heat sinks maintain optimal operating temperature during continuous high-speed runs.
