Can you document for others how you did this update as most people seem to be struggling to get the necessary hardware and software from Bafang.
And also how you contacted Bafang and again, most people have been unable to just buy the M500 or M600 on it's own.
I have asked bafang for latest for M500 and i got below one. I have digged in the internet and its known f/w people are using for M600.
Maybe you can just flash this f/w also to M500 and it wil gain some power?
It seems @patdam have 250W - M500 (hardware) and this exact firmware. @Zimmerframethank you, we have the same hardware but not the same soft. mine is
normal 48V 18A
