Bafang M620/G510 (and all other Bafang motors) now on CAN-BUS (2021+) rather than UART (2018-2020)?

[ETinVT]

For the Canbus version of the g510/m620 the same restrictions exist as for the other m500/m600 motors.
You can just adjust max speed and wheel size

Does anybody have a firmware file for the m620 canbus 48v?

THIS! So I have version CRR10MC4830E101118.1 flashed to my ultra. I've been searching for months for such a file but no luck. The m500/m510/m600 has a ton of versions and variations: https://github.com/OpenSourceEBike/Bafang_M500_M600/tree/main/Firmwares/Official/Motor... where are they coming from? Any leads on firmware variations/files for the m620?

Just writing to confirm that you were able to change the tire size and speed limit on the canbus version of the bafang ultra.... did it go ok for you?

Leaks basically...

Can I unlock the 25kmh limit on a bafang RM GO20.250
hub motor, it has the round 5 pin connector between the display and controller. I have tried the 1919 code but the speed limit stays locked.
Thank you very much for any help.
Matt.

use this one, I had it specially made by bafang, no speed limit CRR10MC4830E101101.1.06_220506.bin

Yes you can use this one

THANK YOU! I've also sourced another firmware file but I suspect it's for the m630. Hoping I can find my current version of the firmware and then I 100% plan on flashing this. Thanks again!

May I ask how you went about sourcing a firmware file from Bafang? I'd love to reach out to see if they'd send me a backup copy of my firmware file.

Leaks indeed! Speaking of, I now have 3 ultra firmware files . I was fortunate enough to be provided my original firmware (18.1) from the company I purchased my bike from. They are currently working with Bafang to create an updated version based on my feedback. I will 100% provide those files once I've wrapped up all negotiations. In the meantime I also got my hands on v41.1 which is similar to v1.1 but without the terrible decay time when you stop pedaling. the only downside is the speed limit is set to 16 mph, but you can set that higher after flashing within the BESST app.

Guys, anybody has a 750W USA version of firmware file? CAN version.
Hard to get.

 

[mcfizzlestag]

The title is a bit misleading as its still fairly easy to get m620 UART kits from GBK (and likely other sources). I was hoping for a m620 UART firmware that doesn't have as aggressive of a power save mode than the current stock one has. At the moment, once you drop below 47V (with 52V controller/motor), you are limited to 13A power draw (43% of your current limit). Its like hitting a wall power assist wise when you are hill climbing. Bafang lists the motor ideal for fat bikes and cargo bikes, but either of them should have a large enough battery pack to easily handle the voltage drop they seem to be trying to protect our packs from.

Hello.
There is a good news - I released open source service software OpenBafangTool 2.0.0-rc that supports bafangs with can bus

Hi, can you use it for g510 calibration, or is it just for motor settings? Thanks. I am having troubles after I replaced my faulty controller. The new one doesn’t have pas or throttle, but everything else seems to be fine. I guess it needs to be calibrated. Please; help me if you can.

Thanks a lot!

If your controller has CAN interface, yes, you can easily calibrate it
