hello, I come to the news, I finally succeeded in bypassing the login to find myself with the same functionalities as my classic accesses.. the pro script does not work? how to access the engineer version of the software? I use the official interface, does not work on version 1.2.16 .. how can I do? thank you

I don't understand your post, probably because of Google Translate. I will connect to the display and the controller via Besst. I can't increase the speed but only decrease it. I can change the firmware. Besst worked for me from 2.1.18 up
 
Hi,

I would like to know why I can't read my paprameter with besst tool pro?
I have a error message
thanks for your help

I would like to update my firmware but I have a failed message after the sound of besst tool

Slaine, as far as I'm aware the M600 firmware is not useable with the BEEST Pro. Only the later revisions of the M510. If you wish to upgrade the Firmware then you will have to use only the original BEEST software.

Hi,

thanks for your help.
 
Yes, but I believe nobody has seen different fw versions for the tool itself. I might be wrong though

Hi, I just update my M500 36v with CRX10NC3615i142017.5-28-2230-20200519-2.bin (Leader Fox stock firmaware) and it is amazing!!
I'm gettting 850w peak. 20A.


I hope that I will not burn out the controller 🤞. But as it is stock firmware, should be OK!

Hi,
I also have an M500 engine and would like to flash the firmware to something more powerful.
I currently have CRX10NC3615i142055.8 firmware

Are you still using CRX10NC3615i142017.5-28-2230-20200519-2.bin firmware??
Is everything okay in the long run?
It is interesting that the power is around 18-20A, while the firmware marking is 15A?

Yes. I'm still using it and it is great. More than 3000km without any problem.

Could you describe how the motor behaves when the voltage drops below 35V? How many W or A will the control unit limit the current? I mean when using FW CRX10NC3615i142017.5-28-2230-20200519-2.bin
 
Hi,
What actually happens if I upload the M600 firmware 36V to the M500 motor? Assuming I change the first byte in the firmware to upload it.
Can I damage the engine? What power will the M500 motor go if I use the 15A M600 firmware? How many amps max?

It will halve the output power.

At this point of knowledge that we have - to go higher power on M500 you need to have controller from M600.
I got one, i am on 18Amps (actually this firmware marked 18 have 20A peak 48V) since the year. Working like a charm for me. Downside its slightly overheat if you ride at full speed for example on 15-20 minutes, then its cut power to 14 Amps - but at this point - its cooling very quickly - for example one stop on red light and you're cool enough, so temperature protection is working correctly.

Is the 17A FW on Github not enough for you? I am satisfied with him.
 
Hello everyone. I have a Bafang m500 motor for sale. in the set: motor, cranks 170mm, display and shifter dp c240, hub speed sensor and all cables necessary for connection (motor, battery, screen, sensor) I will post pictures later and price please message. the engine was used for 700-800 km. completely correct and functional.
 
I just completed an M600 build and have firmware 46.9 installed. Has anyone compared this firmware to other versions? I ask because I was riding with my father (who's 80!) on the steep and his Brose was in a higher gear than me and going much faster up hill. I can keep the cadence fine but to do so I had to use a lower gear and he basically trounced me up the steep fire road. Put differently - I tried to be in the same gear and the m600 could not match the torque. Note again he's 80 and I'm in better physical shape so it was not a "if you push harder you'd keep up" issue.

Of note, I had more battery left by a lot (un-scientific of course) and my gut tells me I'm faster on the flat.

Has anyone compared 46.9 to other versions? (I read the whole thread and see no reference to 46.9 but if I missed it I apologize)

We don't have a bin file for 46.9. If someone have - please share and then we can make tests.

I have the besst tool. Can I grab it? if so how? I looked around for a "download this firmware" command or button and got nada.

Has anyone found the 46.9 bin?

I have a question for those who know...

This is my display.... on firmware 46.9

https://photos.app.goo.gl/sRUCVhzoVub8SgjY8

Note in the pic the watts cap at 750.

This is another m600/e10 bike ... on unknown firmware

https://volitionebike.com/wp-content/uploads/2021/01/DSCF9575-scaled.jpeg

Note in the pic the watts cap at 1500.

QUESTIONS
1) Does this suggest my new firmware (46.9) is capped at 750 watts?
2) Are there known firmwares that allow up to 1500 watts?
3) If so which ones? (i'm assuming maybe 46.7)
 
New M600 43V controller replacement not flashing with BESST tool (BT)...here's the error message: "Main data is empty. Please check whether controller is powered".

1. It reads the HMI display, but not the battery or controller when BT is patched into the display.
2. The power works mode is "on" because I use vibration mode for on/off.
3. The power and new controller work but with rough transmission engagement. Plus, the 20 mph cutoff is now 15 mph limited.
4. HX: Error code 30 was originally occuring (was advised to replace by a Bafang M600 dealer) thus the need to change controller. I also just overhauled the motor with new grease after 2,500 mi.

Pissed off for something that should be a quick calibration. (Even if the old controller wasn't really bad.) Frustrated that no help from my LBS, who typically hate Bafang anyway.

Suggestions or similar experiences? Any assistance is appreciated.
 
Hi folks!
I currently have crx10nc3615i142017.8 on my m500. Where can I get a backup for this? Latest on GitHub is .5 dated 2years ago.
And where can I get the 12A FW that many were pleased with..? @Kyokushin ?

Hi, there is nothing more than we have on github. For your engine best we have is 17A firmware.

Thanks! Is stock with 15amp? My display says 490-500wpeak ((about 14 amps?)dp230)
Is the 17A FW ok to run on the stock controller?
My main thing I want is to have some better response on the higher level.. 🤓
