Mine has the source of variable regenerative braking. Check if there is any difference between yours and mine. Places a photo of the pcb.

I have been trying to connect to my 72V 100A Sabvotron controller for almost a month!
My windows 10 laptop gives me a "Device descriptor request failed".
I have ran every diagnostic tool and even had to disengage windows control over unsigned drivers (ch341.exe).
It seems windows views the controller as a device rather then a serial connection via USB.
The red light is on on the contoller and green light stays off.
The throttle, ignition and speed control all work fine (no load).
I have tried three usb cables and spent countless hours in front of my laptop.
I will be happy to donate to charity or even your pay pal account if you can solve my issue. I am that desperate!!!!
Cheers and thank you!

I´m using Sabvoton 48V 100A (new gen.) controller for my e-scooter project. Now I have connected controller to my bike but there seems to be one problem I can not overcome:
Acceleration works fine but just after releasing throttle (to decelerate), overcurrent error is flagged (ID_8) and controller requires restart. Also, right after releasing accelerator, a punch from motor can be heared, sounds like motor attempts to make a brake. If i don´t remove my hand from throttle on full speed, this does not occur. What could be the cause of this and how could it be avoided?
I am using 48V battery and BLDC motor with reducer transfering power to the rear wheel via chain and sprockets.
Also I do not exactly understand why hall angle test gives out different hall angle values. For example, testing with currents 15-30A I got hall angles from 4-8 deg. When I physically measure hall sensor angle from my engine PCB I get 17 degrees. Why does this value vary so much and which result should be trusted?
I have attached several pictures of my initial setup.
Thanks!
mate, I had the same issue today with my Sabvoton 72200 and found out the the throttle settings have been set by default to 1.11V and 4.40V, but in testmode I had 5.00 at full throttle. I figured out these new settings 1.13V and 5.00V and it worked well.matschi140 said:zzrider said:Hello,

I have nearly the same issue, i don get error but after releasing throttle at full speed the motor brakes relly hard until standstill.
After stand still i can accelerate again.
What can cause this problem? anyone an idea??
Thanks
