New 200A Vesc based Flipsky ESC

You could try the LIFT / FR way: an inlet in the pod nose that sends water up to your ESC without pump. See here and later posts:

Ya, im thinking of a combob 5v pump and that inlet at the nost should be enough

I had a 12v pump with temperature switch as a backup just in case I needed it and it’s never ever kicked in! In my newer build I just took it out. Now all I have in my compartment is a battery, ESC and receiver. So much simpler!

Totally agree with Jezza! You don’t need a pump to get enough flow to watercool your system! I used to have a 12v pump and I ditched it. Now I don’t have to worry about the pump sucking air and turning it on/off.

Which ESC did you use with no cooling ?

Jezza · February 9, 2020, 8:36am

All ESCs need cooling! I just didn’t use a pump. Instead I used natural flow of the water with an inlet in the nose cone. If you don’t use water-cooling, you’ll need a large heatsink for passive air cooling.

Si which ESC did you use with passive cooling ?

Jezza · February 9, 2020, 1:00pm

Freely Arc200. Any ESC with a proper temp cutoff will work though.

What hose diameter are you using?

Jezza · February 9, 2020, 2:23pm

4mm ID 8MM OD silicone hose.

You could probably use the VESC 75/300 with passive cooling but you may need to take some breaks if you want to ride hard and fast for an hour straight as passive cooling can only cool it so far.

I’m setting up my 75/300 in an aluminum box as a heatsink, wrapped in copper tubing, and don’t plan to use a pump. Just ram pressure water cooling from the nose cone.

Vicdes2 · February 9, 2020, 6:59pm

Did you fill that box with corrosionX?

Jsonnett · February 9, 2020, 9:06pm

Are you kidding? Its @Flightjunkie. he fills everything with corrosionx!

Joking aside though. That would probably be smart. That ESC would be bombproof if so. Looks great!

Vicdes2 · February 9, 2020, 9:16pm

Lol that’s what I thought! Talk about going for the overkill lol!

Flightjunkie · February 9, 2020, 10:02pm

Yep. My expenses 75/300 VESC is submerged in about 2" of corrosionX. Works good. Bluetooth signal is strong

Flightjunkie · February 9, 2020, 10:03pm

You got me figured out!

So has anybody reported successfully or unsuccessfully running the water cooled Flipsky 200 amp VESC on 14S. It does say 60V max. Which is more that a very fully charged 14S battery. Efoils dont require regen braking.

Jsonnett · March 3, 2020, 2:27am

I am loving my Flipsky 200A VESC on 12S and flipsky 65151 motor. I have heard that 14s might damage it though. Ratings say 12S with voltage spikes up to 60V.

Flightjunkie · March 3, 2020, 3:06am

I messaged them before buying my 75/300. They said it will not work on 14s.
