Bafang m510

[Dado]

Hello guys.

Adding 43V 18A FW v 5.0 (so peak up to 850W ) - have not tested it yet.
Edit: Works with "old" motor version (the one where 52V version 3.2 does not work )

Hello guys.

Adding 43V 18A FW v 5.0 (so peak up to 850W ) - have not tested it yet.
I suppose would work with "new" motor version (the one where 52V version 3.2 works )

is it safe to test it with 48v battery?

 

[Dado]

Yes, would work. But will be overheating when you would ride full throttle for few mins. Even on 43V it can be overheated on a medium hill.

i never use throttle, ok i will try. hope it works.

Could'nt an administrator open a new Thread for all information about the m510 and the different firmwares with all the details to bring some more order into it? I do totally not understand anymore what firmware i could install on a normal m510 with 48 v battery and which not.
In my eyes everyone how is posting in comments should use the footer to comunicate what motor, firmware and battery he is riding before replying.

 

[Dado]

Mate, it is not complicated. You just need to wait for 48V firmware for M510. You can play with 43V and 48V firmwares, you wont damage your motor (some firmwares have high temperature cut off, or not much good power down regulation, so just avoid running full throttle for longer times). And if specific firmware is not meant for your controller ( due to hw changes on PCB or different microcontroller - we need to find out) it just refuse to flash.

This is for M510?

 

[Dado]

Yes, check the numbers after "i"

 

[thaeber]

Yes, check the numbers after "i"

Thanks mate!!!

 

[thaeber]

Yes, check the numbers after "i"

Sorry for another question: Do You know cut off voltage with this firmware?

Can not tell, as I can not flash it into my motor. I suppose would be 3V*12

I put it to github repository, it seems to be working in versions for 3.0 (same byte-lock)

Uhhh…36V only. With 13S this means 2,78V per cell. Very low. Do You think BMS will cut off earlier?

upgraded battery 14s 4p, 21700 cells. installed FW 52v, and the engine works completely differently. the torque sensor detects the pressure on the pedal. power is linear through all cadences. it finally works! no more cutoff power while driving. today on the first ride spent 24%, 25 km 1000m altitude. there is still room for finishing the firmware!

 

[Dado]

Depends on BMS setup. I like when it is going down to 2.8V per cell. My BMS is not tripping with 43V firmwares, just you will start to feel some power outages and strange pedalling assist when you pushing it too low (plus some strange % SOC calculatiin then - which I dont understand as motor is only calculating % from battery voltage) . No problem if your BMS trip - when you not 20km far away from home. ))

I have now 20A firmware in M510 and it shows 1150W. ) But thats too much for such a small motor.

20A in M510 is my dream,

For what Volts battery is make it and where is this file ?

Thank

 

[Dado]

Not a dream, rather a heater. ) No reason to have it installed, when you cant use it and you will be abusing motor. Its 43V FW.

The 52V firmware reduces the power at 10% to max 400W and 200W at 5%, but the voltage is still 47V at 5%. Not optimal but better then nothing.

U use 48v or 52v battery?

Remember that you are measuring that voltage at rest, under operating conditons of say 400W's I would expect that to be below that level somewhat.

I've now been using that setup for over a year now on my M600 ( and for several years before that on the TSDZ2 engine ) and think 52 volts suits these motors extremely well. There's a real different feel to the engine from 48 volt to 52 volts and wonder if Bafang had intended all along to go to 52 volts, after all it was a voltage that the BB engine users had been using for some years.

For all those using 52 volts you need to try shorter cranks, it seems to put the motor into a real sweet spot with the higher cadence.

 

[Kyokushin]

Only issue is the 52V is not legal in Europe for road use in pedelecs. Of course if you dont care of this then 52V is only a pure profit.

@Rob Rides EMTB hello colleague! the whole dengfu-bafang world is trembling and waiting for your review of the new firmware! what are you waiting for

I ordered an M510 48v with the bluetooth C241 display from Changzhou Fieldebikes Co., Ltd on Alibaba and I received the M510 in less than a week in Florida. Awesome motor. I now have to wait for my carbon frame. I will make a custom battery to save weight.

Wow, less than a week is so fast. By air?

If they use UPS then that's about right. If they use the cheap china option, then 1-2 months is more realistic.

Write a link so as not to waste time searching for a seller.
