Hi Builders.

I’ve flashing my VESC v2.18 PBC v4.1.0 but when jump on the board it too slowly (about 5km/h I guess).

Before It was work great 30-40 km/h. Please help me take a look.


#2

your battery cutoff is at 28V - what kind of battery are you using?


#3

I’m using 8s


#4

Lipo or Lifepo? Whats the voltage?


#5

Lipo 4.2v max


#6

You should be able to go higher on your battery max amps setting with Lipos.
What are the specs on your 8s Lipo?
mah?
C rating?
Oh, just noticed your running FOC.
Could be your FOC settings.
Still 25a seems low for batt max amps

Check your nunchuck settings under app config too - make sure your band is calibrated correctly.

25A seems low (half of what it should be) on batt max unless you’re running dual. I didn’t see multiple esc over CAN ticked off so I’m assuming you’re on single.
