Kilovolt Tech Talks EP005 - QS138 Liquid Cooled Motor Review & what you need to run liquid cooling 

5:51. The cooling properties of water are first rate, practically nothing on earth out performs water. The problem with water is that it freezes. Which is why in automotive applications we add "antifreeze," but glycol's (aintfreeze) cooling capabilities are inferior to water. Which is why in racing, people often run straight water, but you have be very careful to drain the system afterword, as if it freezes, due to the fact water expands when it freezes, it will destroy basically everything it is left inside of.

Pure water is the best coolant that exists. You mix coolant to avoid corrosion and to raise the liquid boiling point.

As a person living in Saudi 🇸🇦 X 🇦🇪 ... thanx for the video ... cuz its getting hot

Super informative video!!! Keep up the useful videos👍

Thanx for the info! Yes please on the review of the 165 and 180.

Hi, how much KW do you expect this liquid cooled version can safely withstand?

How do I get one for my 8000w electric motor

Now I want to use it for my electric fast boat conversion. Initially I was thinking about 138. How much power it can hold with water running through, can you test it?

Hey guys I‘m having some overheat issues with my air-cooled 138, not running it higher then 120 degrees celsius. They say peak is 150, any experience how high i can go continuous? I‘d like to avoid the whole liquid cooled add on‘s. Cheers!

bought one of those Qs motors , to remove the motor sproket is it clock wise counter clock wise ?

Hi there. thank you for the video, is there an issue of overheating the air cooled version? I wonder if I will buy water cooled or air cooled. Because it saves more weight when air cooled. Cheers 🍻

Put some bong water in it.Just joking looks like a beast l haven't seen one in a build personally.👍👍⚡⚡⚡

QS Needs to make a liquid cooled version of the 180... why make a more powerful motor with less adequate cooling?

I was thinking of going with a vector vortex/eleek pozitiffmd you think this will fit 🤔? This with a bac8000 would be the power levels im looking for. If not how much modding would be needed for the motor mounts?

I have a QS 138 water cooled just like this one and am intrigued that the length is significantly longer for the w/c vs air cooled. This is not needed for just adding the water cooling jacket so it implies a longer stator and coils - which would impy greater torque thru the rev range. Would you be able to set up a torque-run comparison of the QS air cooled vs water cooled? It begins to look as though they might have under-rated the water cooled version imo.

Hey brother, any info on sourcing these in the UK?

bro how u think i can try to install liquid motor to super soco tc max? just want water)))

you u might be able to use water cooling for a computer

Very informative.

Wouldn't mine finding a way to fit that onto my veloci truck 😂😂

What is maximum power at peak of water cooled QS138 and how long it last 5-10 sec ?

I would love a freaking mount that didn't cost a lot

Couldn't help a brother out and share the sprocket size is it a 3/4 bore 3/16 key ?, just about to check the new vid.

🔥🔥🔥🔥🔥

is that a hall sensor or encoder?

There is coolant that won’t damage electronics. This coolant is used to submerge crypto miners.
