Hello all !
So I managed to make it works thanks to this image, I don't know the author I found this here tho :

I didn't wanted to remove the shell, too dangerous and time consuming. So I just drilled a hole on the minus. No need to wire the plus because the BMS is cutting power from the minus only. I soldered carefully the cable from the right and replaced to the minus of the anti-spark connector.

It's working pretty well, thanks for all those precious informations !
Next project is to try to use the dashboard screen with an Arduino Nano to get speed and average battery levels.

Any updates on this ? I want to get the vesk setup too but don’t have a computer. 🙄

Hi, sorry for the huge delay.
The hole is here to expose the minus of the battery pack. This minus bypass the BMS and will have full-power with the BMS plus. Be careful this is absolutely not secured, no more short-circuit protection !
Drill the hole very precisely and do not go further the metal shell, then remove the grey silicon. Solder carefully a cable which will be your minus output. Be very careful because the battery cells are behind and do not like hot temperatures.
Good luck !

Hi all 👋
I'm working on an Electisan F350 since some time. I plugged successfully a Flipsky and configured it. When the wheel is turning in air, I can get pretty decent speed. But every times I try it on the ground, the battery shuts down for roughly 10 or 15 seconds (voltage drop from 42 to 0 then go back up to 42). I tried to unplug the 3 capacitors of my Flipsky but this is even worse. It may be the battery going in some kind of safe state because something unusual is happening. But the thing is, I can't drive the scooter because the Flipsky settings which got the battery not shutting down is like 10km / h... I didn't tried to remove the battery because I don't know if it's in some glue like the Electisan controller.
Does anybody have an idea on how I can disable this feature or avoid it? Any information will be welcomed.
Thanks a lot and happy ridding !

So is it working with the flipsky ? I want to use one on mine but don’t have a computer. I used a 500 watt controller but it’s big .

It's working very well with the Flipsky ! The app is really great to optimize everything (acceleration, regenerative break, noise), very impressive and powerful.
