Bafang m510
- Thread starter Puschtrale
- Start date
wait time needed before use after ignite, for torque sensor calibration ?The strange behavior of the motor definitely has something to do with switching it on. Today I tried @ficorama version, unfortunately without success. Then I only switched on the motor after starting to ride under load with the result that the motor did not provide any support at all, regardless of the cadence or level.
Then I waited about 1 minute after switching it on and drove off normally and there were no more cut-off‘s. Someone should make sense of it
Looks quite like it, will test again tomorrow different waiting times after switching on. The engine takes longer to boot up than my old Commodore computer

Ok i'll try this tips, maybe engine need times for torque sensor calibration.
You spend so much time on the experiment, thank you, it is very useful to read. I also wanted to replace the M600 with the M510. It is lighter and consumes less. I will not change the motor until bafang makes a high-quality M510 motor and a normal firmware. It takes a lot of strength and patience to buy a frame, motor and spare parts.

Thanks for the tips, Today I did it twice. Turn on switch power then wait for 1 minute, and second one wait for about 30 seconds. And magically the motor can give assist more smooth on light pedaling or light uphill. just a little on off assist when speed below 10km/h.
I think @KaroKönig was right that M510 motor need more time to auto calibrate torque sensor than previous M500 or M600. Big Thanks for the experiment.
But talking about power consumption I think it's just the same like M500 but with more power. Today I used 9ah battery, I rode about 20km with only 863 feet elevation, display shows 82% battery left.
I am glad to hear that
What I also noticed is the different power output at the 3 / 5 / 9 settings. At level 1/9 you get a maximum of 90 watts of support, at 1/5 it is already 180 watts and at 1/3 the support even starts with 250 watts. That means to drive economically you should choose the 9/9 variant

Now I use C230 display which is only support 5 levels assist. Later I'll try with C240 display to test 9 levels.

Waiting for a minute also seems to work on my motor
Try 30 seconds, I think is enough

Good to hear that you guys might have found the solution?

Glad my remembering about the calibration routine on startup is working. I from habit tend to start the motor up before actually getting on it to eliminate the bizarre but almost uncontrollably need for one to rest one foot on the pedal if you are sitting on the bike. Must be something to do with ergonomics and the human brain.
I started the engine, left it on for about 1 minute. I start pedaling and the engine starts right away. 
@KaroKönig thanks, this is worth a beer!
@KaroKönig thanks, this is worth a beer!Thank you not me but @Waynemarlow . He gave me the idea to wait before pedalingI started the engine, left it on for about 1 minute. I start pedaling and the engine starts right away.

I always stay away my foot from pedal when turn on motor, but this M510 need more time than M500/M600 to calibrate. M500/M600 can use straight away after turn on

Wow, that really seemed to work, crazy. Good work guys! No drop outs in the commute this morningI always stay away my foot from pedal when turn on motor, but this M510 need more time than M500/M600 to calibrate. M500/M600 can use straight away after turn on

someone on FB group use M510 43V and do not wait for 30 seconds or 1 minute to calibrate. no problem persist like us which are used 48v version. anyone here use 36V version???

Hi guys! Please, can you advise me where I could buy m510 36V? Can you recommend me some safe seller? I need to send it to Europe (Czech republic). I need just motor, no display. Currently I'm using M500 + DPC241, so display and all cable I will reuse.
BTW if you you compare m500 (with CRX10NC3615i142017.5 official Leader Fox firmware, peak 750w) vs. M510, is there any big performance difference or battery consumption? Does the m510 worth it?
Thanks for any tip!

Contact Chili, I ordered couple of times from her. I can say anything about 36V version, so far i always orders 48v. Also wanna try 36V version.

Don’t forget to order crank preload caps, they changed from M15 to M16! There is also a new lock ring for the spider coming with M510. Also the motor cover is different from M500, will not fit! I would recommend to source all 3 parts with Your motor.

Chili Shen, Changzhou Victory Technology Co, Ltd. via Alibaba, FB Messenger, Bafang M500/M510/M600 FB group.How can I contact Chilli? (I don't know her)
Thanks
Thank you. Btw are there any new firmware for M510 36V?

Yesterday I did a longer ride an checked Voltage level at 20% SoC. I still found more then 46V, while riding the Voltage remained at 45+ Volt. This means, the SoC calculation (remaining battery) is very pessimistic. There is still lots of life left, and the motor can pull full amperage without the risk of hitting the low Voltage cutoff of the BMS. Looks like there is a major difference to the Bafang battery that @VMG Chris is using, with more realistic SoC, and therefore „earlier“ need of reducing Amps allready at 30% SoC. 2nd takeaway: You can drain the Dengfu 840Wh battery completely without risking battery health. Next time I‘ll try that.
