Hi there,
I had a few days ago my second test I had much more success than the first one.I tested with a few friends and we managed to get on foil a few times.
I am kind of surprised how inefficient the flipsky flodable prop for the 6385 is, with a 85 kg rider and an xover v3 xxl setup 2900 w on foil. It is while still accelerating and so on, but at this speed the foil should be around 600 w at the most
On other notes i had a recursive ABS_OVER_CURRENT which usually ended with the rider falling down. i am not 100% sure if this is due to battery amps or motor amps, any help would be appreciated!
The biggest problem and the reason why the test got expensive at the end is what I still do not understand. At some point, without further warning the foil stopped working, an i got a MOSFET blown, same as when the cable got cut on the first test. Only this time, no cable was cut, the only thing it happened is that the BMS cutted the power since i had both the BMS and the VESC cut-off at 36 volts (3v per cell).
I think it is unlikely that a BMS cut can kill the ESC, what do you think? this happened under load… (2700-2900W)
i still have to check if there might be any shorts in my motor cables, which i think is very unlikely…
and regarding cut-offs, i am thinking about starting the VESC cut-off at 3v per cell, and ending it at something like 2.6-2.7v and the BMS cut-off at 2.5v. ludwig_bre recommends 3v startand 2.5v end.
