K1 BlackBox 3 - Smart Bafang CAN unlocker with Auto Set Speed Limit, also to set motor parameters M500 M510 M600

[DaDo.Bzz]

Hello builders and ebikers.

K1 eBikes presents K1 BlackBox 3 - smart device for setting up parameters of all Bafang CAN bus motors. . Works ONLY with Bafang motors with CAN bus (green connector to display with "house" shape connector - see picture).




Tested with M300, M420, M500, M510, M600, M615, M620, should work also with hub motors with original Bafang controller.

For more info, video, usful tips, user manual and ordering over google forms: https://forms.gle/iBtY9dX9iZMQSRQw7
- check it, wont take more then 10 mins.

Following video with older version BB2, behavior of BB3 is the same.

- Device is plugged in front of display and comes pre-set with your desire parameters - I gonna send you the questionnaire during ordering process.
- Plug and play - by press and hold Plus button you switch between High and Low speed limit.
- Auto set Low Speed after motor power on - limit speed will automatically set to Low speed :thumb: - can be turned off.

- Set new motor parameters by clicking over PASS 012321 (wheel circumference, wheel size, M510/M610 also Max power, Acceleration, Support level, RPM, Startup Angle - only with latest M510 motor FC2.0 and firmware version 8.1+). You can go back to your original parameters (device will read and store these parameters when first time motor turned on) by clicking again 012321 (go to pass level 0 and then press quickly 3 times plus and 2 times minus). - many people were asking me about this - if you wanna give ebike to service.

- You can activate new parameters and unplug the device. Or to have installed device permanently and also use Autoset Low speed after motor power on.

- You can easily set any Low and High speed and all other parameters by connecting over USBC to computer or Android mobile phone - step by step how to document included.


- Install inside of your frame and hide the device. Placing into a head space would be the best. Specify length of cables you want.

- Works with every battery voltage (36,43,48 and 52V, max allowed voltage: 60V)
- Case size: 50x26x11mm

Interesting stuff, thats best solution for people who want to have legal/offroad modes in modern Bafang CAN based bikes. No downsides.

Dado nice job. :thumb:

New ultimate version under developement, will be ready in a month...

Propose a name for this device here, will ship a small present (small bicycle lights + water bidon) to person, when I use the proposal.

Black Box was just first idea. BB can stand also for Bafang unBlocker.

First BB2 sold. Only 3 left - again problems with microcontroller supply. Mid January awaiting availability.

 

[DaDo.Bzz]

BB2 v2.1 now with support of new Bafang dispalys.

 

[DaDo.Bzz]

BB3 v3.0 supporting latest M510 motor to set all the parameters. Default bafang setup from factory is really weired, max power: 50%, 75%, 100%, 100%, 100%
You need to have latest M510 with FC2.0 controller and firmware at least v8.1 (for 36V and 10.1 for 48V)

 

[DaDo.Bzz]

V3.2 - now supporting also motor Calibration (needed when u replace controller, also recommend after firmware flash), ODO set/reset (only on new displayc DPC245 and later), info screen (readings as is - this is what I get from motor

Now discount 10% for people who add code "endless4ever" into ordering form under Notes.

If you interested in M600 firmware without power limitation (putting full power even at 10%) check K1 Flash.
Also one version with lower power on PAS1 (150W) and full throtle at each PAS - which is great! Finally.

Hello.
Have managed a little breakthrough - removed power limitation at 30%, for those who dont own original CAN Bus Bafang battery. And you can get energy from battery up till the end (even set Low Voltage Cutoff). A small device needs to be connected on e-bike permanently. Yes, looks like it is a penalty, when you not using original CAN battery - to annoy people.

It is not easy though to make correct translation from voltage to SOC without fuel guage chip inside battery BMS.

Can be out in a month. Lot of developing and testing (it is time consuming as I need to discharging battery in real ride)
Could be named K1 BBR.

Any ideas are welcome.

Sucking 19A at 29V

Does K1 Blackbox 3 also work with a Bafang M200 motor ?
Kind regards and with compliments Roland
