I launch this subject to avoid necessity to read all the BESST tool subject to solve an problem

Bafang m510

More range because of less power i guess 🙃. And if battery status is never shown correct it makes it hard to trust what your display says 😉 go home when it showing 40% left :D Just enjoy the ride.

BESST

Bafang description

I have installed it, i can read my controler and update firmware in my M510 with it, but no more.
when i read all i have message"fail read" (i suspect it is beacause it can't communicate with the battery)
i can modified the setting in the displayed screen, but i can't send it to my motor ( send button inactive)
i have ofen "ERR 30" displayed on my bike display during manipulation (i unplug/plug BESST tool connexions and it's disappears). i'm logeed with my BESST tool account (not pyton login used). sombody can help me ? i want to reduce the acceleration parameter to see if that solve my problems of cut

Not sure if this would be of much help, but I would recommend to try using the bypass script. Perhaps your level of access doesn't allow such modifications.

Also, from what I know, everybody who has tried changing acceleration parameter didn't really notice any difference. But then again nobody 's experiencing problem like yours. Also for rev 1(rev e) there is only one fw that supports adjusting assist parameters. Not sure about rev 2 though
 
where is possible to find tutorial to use PYTHON with BESST ou BESST PRO ?
 
i installed python and when running the loginbypass, im getting line 72 error. Does anyone know how to fix that?
 
What is the error code exactly? Like unknown function? Undefined variable? Are you sure you have all the required python modules installed?

i downloaded python, installed simplejson, change host file to 127.0.0.1 pointing to test.api.besst.bafang-service.com. Run loginbypass from GitHub and got that error
 
you need to use loginbypass-pro.py for besst pro
from Git Hub
normal loginbypass.py does not work
 
Got just new M510 and Bafang Pro can not read it (maybe new version of Pro needed)! So bafang is not compatible even with themself. ;)
 
I have new version of M510, it's call FC.2 version. Connect with Besst Tool Pro and it can edit Cycling parameters. And i can feel the different when i changed each parameters. Just for bafang to release Android app for tuning like Shimano EP8.

Do u feel also some acceleration change?

which nb hardware and software have the controller ?
 
Hello everybody from Quebec city

I have a ebike with Bafang M600

I have the BESST cable interface, the BafangPro software for Mac, Python is install with the script LoginBypass-pro.py

When I try to read, I receive a Failed.....

When I check my setting in the Display C240, the Torque Info Flash... see the pic.

Do I have a problem with the torque sensor ? A Cable not full connected ?? Your diagnose will be appreciate

What did you mean by "using old besst" ??

Tomorrow, il will open the motor to see if the the torque sensor is attach to the controller. I saw video about remove, install, and change the controller. The cable for the torque sensor is short..., maybe

Any other idea ?
 
I have updated the last rev (1.0.4) and i can with it adjust all parameters of my M510 rev 1.0

does somebody can explain me the "current limit percentage". originally all levels are set to 100%. Nevertheless in use it have différencies between motor assist following the levels selected ? I have tried to reduce a few (- 20%) the level 1 and the assit was reduced a lot (too many). in waiting of more explanation i will return all to 100%, i have only reduced the startup angle to low and the acceleration to medium.

Current limit is like this.If your firmware allows 20 amps max and you set this to 80% , you should have 16 amps max.
I did it smilarly on my m510 fc.1.0 and have on 80 watts max on lvl 1

Thanks.
Those i don't understand is that when all settled at 100% ? We have various power limit following the level ? That whould mean that 100% at level 1 don't corresponding at the 14 A of the firmware rev, but at lower value.
The max A value (100%) in reality can be reach only at level 5.
 
ok maybe you are right. I didnt try 100 current on lvl1.Bu what i think is that they have set a limit on every lvl.For instance 10a on lvl1 12 on lvl 2 etc.
When you change the limit you get a percentage of the maximum set limit of the corresponding lvl.
If we say lvl 1 gets on 100% 10a you can set it to let say 50% and you will get 5a max
 
Patdam, you are overthinking it. ;)

It is just a maximum current limitation from the value you see in bin file name (two numbers before "i").

And why we see such a high limits also on PASS level 1 (from factory it is set to 50%)? I suppose it is because of new Support level parameter which should tell to controller what assistance power it should give to your pedalling power - can work this way. But after short ride on FC2.0 it is still too powerful on PASS 1 and u pedalling almost freely. I think this is coming from not much sensitive torque sensor - so then not easy to regulate optimally.
You put some torque with legs, motor will count how much needs to be added by motor according Support level percentage and will count the current to phases. Max current is top limitation.

So still good to limit max current on PASS 1, to get good range.

Similar like Innotrance controller - some people are setting max current on each PASS and set torque sensor sensitivity accordingly.

Anyway somebody knows where to set a battery capacity? Dont understand how this range is calculated, when I do not set capacity (When u have battery with CAN comunication I can imagine it can work, as BMS then sending info to controller what is battery max capacity and current SOC). ;) Again a Chinese logic and then it showing only BS...

Hello Bafang Ebikers.

New BB3 device if anybody interested. Can set all the parameters of latest M510 FC2.0. All other CAN Bafang motors support still Circumference, Wheel size and Speed limits - you can switch easily by holding PLUS button. Motor Calibration (useful when u change controller), set/reset ODO (only new Bafang DPC254 and later), Info Screen.

Check this interactive Google form, there are useful tips, videos, pictures, initial/default BB3 setup and how to order

Guys, does your Besst works? Getting white screen on login screen.
 
Just installed a new Fc 2.0 controller on my M510. Firmware is different than i have seen here.
