Waterproof Design: The water cooling pump features a waterproof design, allowing it to operate effectively even when submerged. It is built for durability and long service life. Long Continuous Operation: Compatible with a JR plug for receiver connection. At 5V, the pump can run continuously for up to 15 hours without interruption while maintaining stable performance. Reliable Performance: The pump may generate heat during operation, but this remains within normal operating limits and does not affect functionality or longevity. Low Noise Operation: Designed for quiet performance, making it ideal for applications where minimal noise is desired. Application: This silent 370 water pump is designed for use in remotely controlled boats equipped with water-cooled motors requiring water cooling, without a suction rudder. The motor operates at 36V and can be powered directly from the receiver. Compatible with 6S (728V) battery systems using a 5V power supply. Suitable for RC aircraft carriers, warships, battleships, and other vehicles that require water cooling for electric motors and ESCs. On/Off Control: Connect a switch between the pump and power source. Turn the switch on to operate the pump and off when not in use. Performance Test: Tested to operate continuously for 15 hours at 5V. The pump remains functional throughout the test, with temperature rising to acceptable levels that do not impair performance.
