Quanly 84V 300A Brushless ESC Motor PWM Controller

The Hobiba HB-300A-84V-SL-WP-WC represents the pinnacle of high-voltage, high-current marine propulsion control, engineered for extreme applications. It is the definitive power solution for high-performance electric surfboards, jet boats, racing go-kart boats, and unmanned underwater vehicles (UUVs) that demand uncompromising reliability and brute force.
This controller delivers unprecedented power, combining an 84V operating voltage with a massive 300A continuous and a staggering 1000A burst current. Its core innovation is a sophisticated dual-cooling system, integrating efficient water-cooling channels within a rugged, hard-anodized 6061 aluminum IP67 waterproof housing. This design ensures sustained, full-power output without thermal limitations. Beyond raw power, it offers extensive programmability—including adjustable motor timing, throttle curves, and configurable protection thresholds—allowing precise tuning to match any high-performance motor and application. With comprehensive safeguards and CAN bus communication, it is built to dominate in the most demanding marine environments.
