Re: Electric Surf Board

Hi
are you sure that there is really load on the system?
It seems to be really a too low power consumption.
Could be an issue of water mixen with air, less stress for the motor to handle / put through your jet...
On the other side, try to accelerate up to 14000, and measure the pulling force.

Re: Electric Surf Board

Due to high motor resistance or a bad battery = high resistance in OHM.
The input current isn't the issue.
That was the reason why I switched to the LiFePo4 and now LiPos and no toy battery from HK.

Re: Electric Surf Board

30cm is not too long.
Try some additional caps (from MGM) or similar specs.
I have cable lengths of 80cm...
I think it could be a problem of the maximum voltage. I had to reduce from 15S to 14S.

Re: Electric Surf Board

Really strange picture.
I think you are right with the remote input, seems to be 0 or 100%.
What about your cable lengths?
Do you use additional caps.
About settings, try to increase the acceleration time...to 3 or more seconds.
Next use a servo tester as input and check everything again.

Re: Electric Surf Board

The graphs are definetely not good.
What about the voltage of the battery.
Normally I have 450/500 peaks when the engine ist running on 250A.
And the peaks are occuring only at the acceleration phase...please drive a ramp.
From 0-25-50-100 throttle Input.

Re: Electric Surf Board

In my board I have started to use the water going out from the nozzle/delivered by the jet. But after a run there is a lot of heat remaining in the whole system. So my next improvement will be an update with an additional cooling pump, a filter and a reed switch to switch on or off. The f***ing heat...

Re: Electric Surf Board

Yes that is right...short cables from battery to controller. It is very complicated to explain this in english for me. But look for induzierte Spannungsspitzen, lange Batteriekabel vs. lange Motorkabel... Also very interesting is the SLS Sinus Leistungssteller. And in the end, the Kosmik would be a ...

Re: Electric Surf Board

Hi & good morning Longtime full load is about 240 Amps for 5 seconds. Not too much - I think the problem will be the cable lengths from the battery to the controller. There are indication high internal peak currents (about 600Amps) and this is too much for the caps. Maximum temperature was about 105...

Re: Electric Surf Board

Hi yes it is the MGM ESC. I am a little sad about the situation. We have still 7 days left and I am not sure if I can do an additional ride. At home there are some capacitors - f***... I have already contacted the supplier via Email. But it is weekend - so no response ;-) But in the end I do agree w...

Re: Electric Surf Board

Hello @all

I am again in Corsica and testing the board.
This year everything is running stable - after this morning run I have some swelled capacitors on the ESC.
What do you think stop or go on?
Two years ago I have killed the ESC :roll:

Greetings from Corse

Re: Electric Surf Board

Hey Chris Can you give me some details of your installation. Especially the lenghts of cables, cross sections, connections, placement of the additional cappacitors. I had the same failure twice. My first thoughts had been also the same: Should shut down automatically internal safety algorithms Could...

Re: Electric Surf Board

Yeah looks really good and a little funny.
Have you the possibility to check the speed with a GPS?
Should be something around 25-30 km/h...or?
Have you limited the rpm? From the sound it is round about 13500-14500?
Looks really good, go on with optimization :D

No it is just for fun ;-) At the moment I am using Kokam pouch cells 14S1P. I have worked in the automotive industry and also some years in the formular 1, that is the reason for doing everything in carbon.

Hello I have bought the cells standalone. To do the connection you can use a bavarian system like used in the ultralight powered paragliders. The hard thing is to put the cells into a polyamide film. If you can give me a smart tool to load up pictures I will post some pics of the project. I have als...

Hi at all I have nearly the same setup. As battery I have used a 16S4P 38140SE Headway configuration and at the moment I am using a 16S1P LiPo from Kokam with crazy 53Ah. The Headway setup was really stable lets say idiot safe but a little heavy. Cruising time about 25-30 minutes. It is a 48 Ah conf...

Hello
I have build a jet board with such a configuration.
A LMT 7040 with a MHZ jet with 64mm.
It is not so easy to handle this.
17S3P battery pack, a MGM compro ESC, an Emus BMS,...

For more information please write me a short email.
