Overview
Hobbywing QUICRUN WP 12BL45 G2 is a waterproof sensorless brushless ESC for 1/12th and 1/14th scale on-road and off-road hobby vehicles, supporting 2-3S input and 45A/200A current rating.
The ESC adopts intelligent freewheeling technology to enhance drive efficiency, reduce operating temperatures, and improve stability during prolonged high-load operation. IP67-rated protection is specified for splash resistance, water resistance, and dust resistance under normal usage conditions (see note in Key Features).
Key Features
- Waterproof design with IP67 protection rating; specified for splash resistance, water resistance, and dust resistance.
- Intelligent freewheeling technology for higher drive efficiency and lower operating temperatures.
- Built-in BEC with selectable output voltage: 6V/7.4V.
- Multiple parameter adjustment methods: LCD Program Box Pro, LED Program Box, and SET button on ESC.
- Independent program port designed to avoid unplugging the throttle cable during parameter adjustments; can also be used to connect an external fan or other cooling devices.
- Compact size note from provided description: compared to 16BL30 ESC, 8.3% shorter in length, 7.1% narrower, and 16.7% lower in height.
- Compatibility statement shown for pairing with QUICRUN 2840/2850 G2 motors.
IP67 note: The IP67 protection rating applies under normal usage conditions and has been tested under controlled laboratory conditions. Protection may degrade over time due to wear and aging. Do not submerge the product in water for extended periods, as this may result in damage.
