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

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.
Also check page www.k1ebikes.com for brand new product - BB Racing, which can recalculate SOC of your DYI battery, remove power limitation, discharge battery deeper to get more range, use 52V battery with 48V firmware (or 48V battery and 43V firmware to get more power - usually +100W) and more...

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.

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

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)

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.

Check also K1 Flash with firmware update function. Simple to use, just connect and wait for green light. Comes with SD card with lot of firmwares for M500, M510, M600 and M620. Not waterproof, external power, cant be permanently connected on ebike like BB3.

K1 Flash Light (no firmware upload function) - you can unlock 2 Bafang CAN motors - now special price 110Eur including shipping to EU with code "Endless4ever"

10% discount with code "endless4ever" - enter 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

Hello Roland. Yes, if it is CAN bus motor, then will be working.

New product introducing. BB Racing - can trick the battery. You get more energy from battery. Also u can use 52V battery with 48V motor. Or 48V and 43V to have more power.

Vorrei darti un consiglio: creare una finestra java come quella creata da mbrusa per tsdz2 è davvero user friendly.
perché ho seguito il video e mi sembra macchinoso e mi crea confusione con i comandi rapidi.
without prejudice to the excellent work you have done.

Ho intenzione di prendere un motore M500. Se utilizzo il vostro dispositivo, cosa posso impostare oltre alla velocità? Posso impostare la percentuale di sensibilità alla mia torsione nei vari livelli di assistenza? come livello 1 = 15% livello 2 = 30% e così via?

Hello. Go definitelly with M510 FC2.0 - here you can set also torque sensitivity (aka Assistance level percentage) plus some more params (acceleration, max current, startup angle, rpm). M500 does not support anything - only Speed limit and Wheel size.

Comands are ok. You gonaa set it once and no need to change them usually. Majority (>90%) of customers did not ever connect it to computer. We are setting parameters for customer according his need.

Check www.k1ebikes.com for new device - BB Racing

Ciao. Scegli sicuramente M510 FC2.0: qui puoi impostare anche la sensibilità della coppia (nota anche come percentuale del livello di assistenza) più alcuni altri parametri (accelerazione, corrente massima, angolo di avvio, giri/min). L'M500 non supporta nulla: solo il limite di velocità e la dimensione della ruota.

I comandi sono ok. Lo imposterai una volta e non avrai bisogno di cambiarli di solito. La maggior parte (>90%) dei clienti non lo ha mai collegato al computer. Stiamo impostando i parametri per il cliente in base alle sue necessità.

IOIl Fatto è che mi hanno proposto una bici a buon prezzo con quel motore e dato che vengo dal tsdz2 dove mi settavo tutti i parametri personalizzati volevo capire se era possibile anche con questo motore.
si può almeno fare leggere la batteria non bafang smile?

Sono sicuro che è così, era solo un suggerimento, perché come ti dicevo vengo da osf per tsdz2 è ho modificato i parametri fino a raggiungere un optimum per le mie esigenze e con una finestra java modificavo solo il dato che mi serviva e flashavo, comunque BEL LAVORO!

Hello. You can use any DYI battery with Bafangs. Only exception was M625, where motor started only with original Bafang CAN battery. You wont be able to set anything on M500 (only speed limit and wheel size). Battery parameters to set not possible at all. Here is not possible to set even battery capacity. Crazy. If you have CAN bus battery motor will read its capacity from battery and then calcualating range.
Is true, there is bigger power limitation at low SOC (from 25%) and also higher Low voltage cut off when not using original CAN battery. And this is BBR solving. Also with BBR connected you should be able to run M625 with DYI battery with no CAN bus connector.

DaDo.Bzz said:

Ciao. Puoi utilizzare qualsiasi batteria DYI con Bafang. L'unica eccezione è stata l'M625, dove il motore si avviava solo con la batteria CAN Bafang originale. Non potrai impostare nulla sull'M500 (solo limite di velocità e dimensione della ruota). Impossibile impostare i parametri della batteria. Qui non è possibile impostare nemmeno la capacità della batteria. Pazzo. Se si dispone di una batteria CAN bus, il motore leggerà la sua capacità dalla batteria e quindi calcolerà l'autonomia.
È vero, c'è una limitazione di potenza maggiore a un SOC basso (dal 25%) e anche un'interruzione di bassa tensione più elevata quando non si utilizza la batteria CAN originale. E questa è la soluzione BBR. Inoltre con BBR collegato dovresti essere in grado di far funzionare l'M625 con la batteria DYI senza connettore CAN bus.

Invece per il motore m420 non c'è niente?
