Try on older version of besst. 1.2.18 for example that you may find here: https://github.com/OpenSourceEBike/Bafang_M500_M600/tree/main/BESST/dist

ist good to have a snapshot of VMware Virtual Machine wtih opened besst. It will be usable forever :)

we cant pull firmware from engine so far here are currently avaiable firmwares collected by multiple users: https://github.com/OpenSourceEBike/Bafang_M500_M600/tree/main/Firmwares/Official/Motor a word about versioning - the firmwares are not superseeding each other, that means the higher...

I am curious what is inside. I am not telling to open, but i am curious the controller, gears :) maybe someone will have from service etc.

Only firmware and sticker are different, the hardware is all same.

guys, you dont need to change the controller, its enough to change firmware. Controllers are same hardaware, the difference is software.

47.7V its rather for 43V battery. Anyway, if you owe 43V battery, just change the firmware in engine to 43V (Bafang need send one to you) and will work.

Nice, 36V 19A.

peak power is limited to 15A instead of 18A, thats what i am sure. Unfortunately cant say more, in my opinion the 46.7 is requiring less strength on pedal on lvl 5 to get max power output, i have no comparison to other. That whould be great if you could compare it to other f/w. I tried that in...

Do not know, never used. I only used this 15A (in M500) and finally went to 46.7 because i want to have strongest assist on lvl5 from M600 firmwares

Yes, its for M500. For M600 there is detuned 15A 48V firmware: https://github.com/OpenSourceEBike/Bafang_M500_M600/blob/main/Firmwares/Official/Motor/m600/CRX10NC4815i132020.8-20210924.bin On what firmware on M600 are you?

No such need. Never did. I only needed to do calibration when i changed the controller.

i noticed something simiar on 15A and 18A (46.7) firmwares from M600. Have you noticed that on 15.8 13A from M500? i may be wrong but i have a feeling on 13A 15.8 had no such effect - worth testing.

On what firmware are you? i think i have similar observations but i had no clue because i observed this rarely. At least we know we can push amps and engine have temp protection - thats good news.

Hi, i have a question - how you noticed the M500 have problem with overheating? Some error, power degradation, or just was hot?

Boost works not so bad, at least it „is”. Other brand engines are ending on 25 and thats it. In M500/M600 you can just push boost and bike will ride faster. Od course the best is just connect a throttle and remove this nonsense limit. m500 on 13Amps had around 42 max speed, on 18AM600...

The important question is does it support boost, because only that funtion allowing to ride faster than dog wandering on street.

I put m600 controller to m500. 1.1kW peak, still legit, still working in my daily riding.

CAN is imo huge disadvantabe. With uart you can do everything, with can - nothing as we can see here, at least no one did. Thats the most wanted feature we dont have in M500/M600. To remove a limit and enable/disable throttle at one click.

Guys, i have placed the M600 controller (with 15A limited firmware) to M500 and it feels stronger of course. However i have switched the power output to Ampers and started look on it. I am not sure which one of firmwares now are more torque required to get full power, my old 13A or new 15A...
