bafang M SERIES overrun and battery issues

[pxl666]

hey
i dumped tsdz2 and switched to bafang M series hoping for a better quality and robustness . to my suprise as tsdz2 was weaker than m600 , it delivered power way better than any of my M bafangs (M500, M600, M510) . bafang has more agressive start and terrible overrun , after you stop pedaling it can feed current for almost a second after ... this is horrible ... can anything be done with that ? a friend has G510 uart and it could be tuned via pc cable to get this right . M series with besst and bafang go are stripped of this option ?? are everybody cool with that ??
other annoying thing is restrictive battery approach , display shows 10% , motor cuts down power to 300w max and when home , meter shows 45v on battery ... so it can feed full power for longer - this can't be changed also ??

M600’s have very limited tune- ability although running on 52 volts seems to put them in a better sweet spot, they are quite a decent motor, circa 1200W’s, very quiet and do not strip the plastic gear like the TSDZ2 at higher currents. M510 and M560 have all the tune-ability you talk of via BESST or App except over run which is dependant on which firmware you have, with over 1000W’s available. Over run can be stopped ( I prefer to have it in the type of knarly uphill single track riding I do ) by fractionally rotating the pedals backwards or fitting a brake cut out on say the rear brake ( it’s very easy to do ).

in my view having spent so long playing on and modifying the TSDZ2 engine, the M series are way better motors and other than some water ingress problems ( had more so with the TSDZ2 engine ) mine have been a nice step up from the TSDZ2 engine.

Battery cut offs can be tuned on some motors with Canable Master Pro or OpenBafangTool or simply purchasing one of the K1Racing dongles.

i have ordered besst and hoping to get some good results with this but 100$ cable is stupid to purchase from enduser point of view ... anyways - is this a way to better use battery by loading a 43v fv having 48v battery ?

What motor are you using ?

i have m500 m600 m510 and m560 on the way , currently i wanted to tune m500 but it has unusal voltage of 43v and firmwares i see are for 48/36v . connected besst in offline mode and can't make any changes with this fw , looks like it's locked in some way

Yes the M500 & M600 are old motors in terms of development and are pretty much non adjustiable as far as I'm aware. You may want to explore the thread.

Thanks for that info... I've written stuff with characteristics before so it's familiar territory (a bike computer to send speed/cadence to standard cycling apps, with a derestrictor sneaking in, on a Arduino 33BLE) I did wonder if there was a restart command on the CAN bus that did what a...

There is somewhat new software being developed on Github with some of the posters here to try and get at least some adjustiabilty of these older motors, not sure how sucessful you will be though and sometimes it maybe just worth fitting the new M560 motor and going and enjoying riding your bikes rather than spending an infinite amount of time trying to adapt the older motors. Progress at huge pace and throw away societies seem to rule.

There are other forums which have quite a large Bafang section ( although I think I have seen your moniker over there ) on most of the later M Series motors

ye im looking thru this but it's kinda hard to figure what is right since filenames are just random characters , not describing what bin is for what motor and what voltage , and i don't want to brick motor ...

there is a repo of fw files but still - not sure what voltage and what settings it has

do u know from experience that m510 can take 58v without problems ? been trying to find someone on FB and forums but no luck so far . bafang ppl are famous for making weird decisions so it's possible they made 510 not able to take 58v and fry ...
