If it is placed in normal operation, the temperature will be hot, but it belongs to the normal range and will not affect the use. Operating Voltage: Rated 6V, use 3-6V Voltage: 3 V Pumping waterflow rate: 1.1L / one minute pumping waterflow rate: 300 ml / one minute Voltage: 6 V Pumping waterflow: 1.8L / one minute pumping waterflow: 600 ml / one minute Use range: Silent 370 water pump, suitable for installation on remote-controlled boats that require water-cooled motors and do not have a water-absorbing steering gear. The pumping voltage of the 370 motor is 3-6V and can be directly plugged into the receiver to obtain power. Through the step-down module, it can be directly plugged into 2 -6S (7-28V) battery step-down 5V feed water pump. It is suitable for remote-controlled aircraft carriers, warships, battleships and other series of remote-controlled ships that require water-cooled motors and ESCs. 1It is waterproof and works well in water, JR plug suitable for plug into the receiver, plug and play. 2Under the condition of 5V voltage, the pump works continuously for 15 hours and pumps water continuously. 3Put it to work normally, the temperature will be hot, but it belongs to the normal range and will not affect the use. 4The pumping voltage of the 370 motor is 3?6V, which can be directly plugged into the receiver to get electricity. 5Through the step down module, you can directly plug in a 2?6S (7?28V) battery to step down 5V water pump.1 x Water Pump
