RC Water Pump 5V 370 Water Cooling Pump JR Plug Step-Down Waterproof Low Noise Module Accessory Part for RC Boats Motor & ESC

I have a dual chamber ESC and this pump had no problem pushing pressure through the system. Nice pump.

There is no cooling when the boat is not moving! Esc and motor get hot but not any more

Works perfectly to cool both motors and ESCs on my Miss Geico 36in.

Not good quality.

Easy to plug in via USB breakout board, which is what I wound up doing (though I did test to see that the pump operated with 1S and 2S LiPos, though 2S violates the specs for the pump and I don't care to damage the pump by seeing how long it'd last with 2S). The battery bank I had it hooked up to outputs 5.2V (very slightly over), which comes in a bit under max spec; for what it's worth, here're the results I got: right at 7 minutes to move one gallon (pulling water up about a foot and then smoothly sloping down about a half-foot to the drain it was feeding) ~8.5 GPH at 5.2V (the pump theoretically had 11W available to it) drained 6Ah (real capacity at 5V, not the fake 3.7V capacity manufacturers list) battery less than 1% (that is, the battery bank never moved from 71% to 70% during test). Therefor, pump consumes no more than 510mAh@5V over an hour; or another way, the pump was consuming no more than 2.55W. YMMV at different voltages. The max lift is at least 6 feet. How much greater, I'm not sure, since I was testing in my bathroom; it was choking a bit with my arm as high as it'd go, but this could have been more to do with having the hose nearly straight up at that point. The pump wants 1/8 inch ID tubing.

I am building a gaming PC that is cooled by water. This little pump puts out plenty of flow for that. I had to use a buck converter to change the voltage to get the correct amount of flow, but that was no problem. So far running it for several hours at a time it worked perfectly. Great little motor that seems to be well made. I will update if I run into problems.

After 15 minutes of using stopped pumping water

Worked for me for RC stuff.

Yes, using the correct Peltier coolers with water circulating heat sinks, this pumps provides enough volume at a circulation flow that works quietly and with little power. The fyi cooler uses 3 separate stages of water flow for how cold to go regulation. This pump runs continuously on the inside cold circuit. The other stages cycle as needed to circulate coolant to take heat away with larger pumps noisy fans.

I use it as a water cooling pump for RC vehicles and works well and strong.
