I used multimeter after the bms, it showed 36v
I think the bms is cuuting off, its only 36v. Doesnt make sense.
One more weird thing, that i connect bat ( after bms) to vesc, the led on vesc flashing blue repeatedly. It is like there is no amp is coming out, and the computer could not detect a usb device when i i pluged it in.
Then i switched to laptoplike charger, the veac connected to computer with no issue.
Is the meter negative going to P- or B- on the bms? You should be going to B-, assuming you have an eswitch on the bms. If you’re running a power switch after the bms, you should have the meter after the switch or it’ll always be on.
@Jinra thanks for quick reply. In the case that it showed 64% , yes the meter connected to the b- of the bms. In the case it showed 0% it connected to p-

Yea sounds like you don’t have enough current going through. Did you wire battery negative to B- and VESC negative to P-? Battery positive doesn’t go to BMS at all right?
