Hmm, 200A, 40V, 8kW? I’ll fry my motor?
I guess the 50 is erpm? I’ll need to go for at least 600, so my motor spins a bit and gets cooled better
50 erpm : 7rpm : 0.05v , 10w ? (heat) on the motor ? Motor tested in the water …
Ah ok, so the current ist circleing around Motor and Vesc with low voltage…
Yes something like that , maybe the Ri of the motor needs to be used to calculate heat ? P=rI2 so more like 600w… don’t know, never done it
The motor needs cooling. You will burn all the energy in the motor. We either take big motors or a motor submerged in water.
Stupid 80100 makes trouble with starting in openloop. I guess i have to try and tweak some settings, and i guess its the same issue, like @superlefax has.
Anyway, finally i could manage to run the Motor in low rpm and high current. 190A was max, was i tried. Lucky me, no smoke.
Limited to 180A, cooling was on, it took about 50sec, until VESC reached 75° (i lowered temp cutoff) and limited current.
The current has settled at 155 amps.
Conclusion: 200A Continous: Impossible. (as long you dont cool with liquid Nitrogene 
)
155A Continous is possible, short peaks with 190A too.
With no cooling 75A continous was possible. One day during riding my cooling failed, and it was still possible to ride. But it was no fun. To restart, i had to suck water through my cooling, to cool the vesc for necessary current to get on foiling
Overall: I only need 120A to get on foil, 60-90A for normal cruising/riding.
For me, this vesc works fine with cooling. And how this works, i dont bother any more. Motorcurrent Limit to 150A and i got plenty of spare punch

Last year I did some test with 30w Peltier cell and classic esc water cooling plate , I was able to keep the water freezed on top easily , I could fit 4 smalls cells in série (48v )and 2 water cooling on a vesc 6 size 
Thank you for testing ! Great results !
Did anyone try this vesc on 14s?
12s for most vesc, more : trampa 75/300, a200s
No spikes over 60v , if you have 14s just charge them to 4.0v if possible
Never recorded spikes on my trampa
I’m assuming you feel the same way about the seal 300a ESC by maytech/flipsky? Would be risky to run it on 14s?
The seal 300a is designed for 14s. They mention max 75v spikes on their alibaba page. That’s for the reacher tech.

Interesting! On maytech and flipsky they rate it at 60v maximum! Which is pretty close to the max voltage of a 14s pack!
Might be a nominal voltage? I trust the guys from reacher tech so I’m going to run mine on 14s.
That’s good! Do you know anyone who ran it on 14s before?
No, not yet. That wasn’t a consideration for me.
I’ve opened it up to have a look, and was quite surprised with the quality compared to the flier escs I’ve been using. I’m sure the seal 300a will be fine on 14s.
I’ll let you know if it blows up.
Haha alright thanks! But let me know if it doesn’t blow up as well! I’m curious to see how it will perform!
I have tried both Maytech 200A MTSESC 6.6 based on VESC and original Trampa Vesc6+ on 14s. Maytech on efoil, but only for half a minute because I got water inside esc enclosure and fire. I had metr and in that half minute temperature jumped from 40 to 60 degrees C. In efoil, you can turn off brake in vesc settings, so there should be no voltage spikes over 60V.
Original Trampa Vesc6+ on esk8 on 14s, with brakes. granted, battery was charged to 55V only, but it was ridden for few hours and not a single problem.
I will try this Flipsky 200A ESC on 13s or 14s. reps from Flipsky said 12s is max, but I will try it anyway. Water cooling should help here.
Hey Tin, did you eventually find time to test the Flipsky 200A ESC on 13s or 14s despite Flipsky’s warning at 12s Max ?

Hey guys, ive the flipsky Vesa 200A. Only have a work laptop so cant install any software (yet, waiting for work to free it but it could be a while) but I see it has bluetooth. Is it programmable via bluetooth? And does any one know which app to use or a link? Im android
You don’t have to install anything. Just open the zip file and start the application.
