Bafang Max Drive - configuring

Post by e-bikeNZ » Feb 24 2018 4:17am

Background
Doesn’t seem to be a lot of info out there yet on configuring the Bafang Max Drive even though e-bikes with this mid drive are becoming more popular, so thought I’d document my experience with it as a starter for others interested in configuring it.

My e-bike
My requirement was a lightweight city e-bike I could ride without assistance on the flat, that could jump kerbs & cross parks, but which also had pedal assist to get up hills (I have to climb a hill that goes from zero to 430 metres above sea level to get home). I ended up buying a Bottecchia Krypton 29er which has the Bafang Max Drive (250W with 36V 13.6Ah / 489.6Wh battery) and one of the attractions was that you can configure the software for this motor.

Settings via display unit
The first thing I did was correct the wheel size & up the speed limit in the Display unit. Mine has a Bafang DP C07.UART display so you have to press the “i” button twice, scroll down to the Password option, enter 0512 then set your protected parameters (e.g. wheel size 29, speed limit 60 kph).

The DP C07 is similar to the DP C10 but without the usb port on the side and here is a link for a Youtube video that shows how to navigate it. https://www.youtube.com/watch?v=0YEDKbNS1oQ

Configuration Software
The Max drive configuration software is the same as that used by the Bafang Ultra Drive (i.e. 1000W motor that also has a torque sensor) so has the Torque tab. The other tabs & settings are as per those used by the BBS01, BBS02, BBSHD. All the information therefore is out there already, it’s just a matter of finding the good oil.
The following is the key link by Karl Gesslein where you can read about the torque settings and download the configuration software. It also has links to other relevant programming pages.

The experiences of robocam with his Frey AM1000 are also a recommended read,
especially his youtube https://www.youtube.com/watch?v=kWCR3iV3d9I

USB Cable
You will need to buy the standard USB cable to plug in your laptop to the bike. I bought mine from bike-union on ebay https://www.ebay.com/itm/331764807313?V ... 1764807313 and have had no problems. You can also get them from Lunar https://lunacycle.com/parts/bafang-part ... ing-cable/

My Configuration settings
My configuration settings are different to Karls as mine is just a baby 250W Max drive rather than a 1000W Ultra Max drive like his. As always you configure/modify at your own risk.

Where did you find the configuration software? My understanding is the BBS02/BBSHD software won't work with the Ultra Drive.

Just out of interest e-bikenz, what settings did you change (if any) via the configuration software?
And if you did what difference did you notice in the ride?

Cheers

Hi idave, Main Changes as follows:

In Basic settings on my bike the Limit Speed was already 100% on every Assist level, so I just spread the assist levels for a gradual increase of assist on most settings, with a jump at the top end for Hills.
In the Pedal Assist setting, Current Decay at 8 and Keep Current at 80%, so it didn't fade if I slowed going up hills.
Left Work Mode at 10, as performance seemed to drop off slightly up hills whenever I raised it.
In the Torque Settings, reduced the Start & Full KG so it was less effort pedaling up hills & likewise raised max current to 100% on all settings except Speed0. Lowered the delta voltages also across the board, as this appeared to again make it easier pedalling up the Hills.

As you can probably guess, I don't really use power assistance on the flat except when I am in a hurry and then on Full Assistance can easily do 30-50 kph. My focus has been really on making it easy to get back up a very long steep hill on the way back to my house and it's certainly achieved that.

mine is just a baby 250W Max drive
I ~think~ the Max will consume more than 250W on input..
For example, I rode a Bafang Max powered bike, and the displayed power showed peaks of like 700+ watts.

Does anyone know for sure? (I'm sort of a noob here.)

Thanks e-bikeNZ
Nice to know what others have done successfully. Over the next few day I will be trying a few setting changes.
Have some big hills around here too.

Hi e-bikeNZ
A question about the Max Drive software - I have downloaded it etc but it does not recognise any com ports (just blank).
The original BBS02 software recognises the com ports as does some upgrade software I did for the MAXdrive (from the maker).
Did it work first off for you? What OS did you use. I am running Win10. Tried 2 different computers and zip com ports.

Any tips?

Cheers

iDave

This wound up in the BBSHD thread, but really belongs here...

This is a picture of the controller board in a recent Ultra Drive. Circled in red is the shunt resistor. Stock value appears to be 5 milliohms.
By decreasing the shunt resistance, the maximum current will increase.

apparently bafang changed the shunt to a double one V1.5 power pcba. Mods will be much easier.

here is mine, at least produced on or after march. 2018 (some sticker with date code in it):

Mosfets are different too (P/N: EK06808 1747 KY, unknown to all major brokers)

The 1.5 also has en embedded hall sensor that reads a magnet attached to the rotor tip.

Interestingly enough, the small pcba with the hall sensors sitting in above windings is still there but left unconnected. Bafang must have had some old stock to flush once the new sensored board was put in production.

Oh, and the cable screw-posts are labeled ALIEN# :lol:

How did you solve the problem of the port not being recognized?

That's an interesting setup with the hall sensor. Seems like it might be prone to timing errors if the board position is off a tiny bit.

I like the Alien connections. Maybe something was lost in the translation or they are using some highly advanced technology from another planet.

Hello everybody. I want to choose a light new bafang M600 G521 motor for myself. but I can not find the information on the possibility of programming power levels as on bafang ultra M510. can anyone have experience with this motor and software? I understand that the model only entered the market and there is still very little information.

all that I was able to find out in Chinese supplier this is that they do not know whether there is an opportunity to program power levels like models bbsxx. And there was a new connector to connect the display. but he still has 5 pin.

Hi All,

Any clue on how to configure DP C07 display/MM G330.250 motor without usb? C07 does not have usb port nor my menu does not have psd view -> cannot edit LUd or SPl option digits from default.

Thanks in advance!
