Are you not confident with power limitation at low battery SOC%?
Would you like to set lower discharge cut off voltage to get more range from your battery?
Would you like to remove throttle speed limitation?

Theres a new device BB Racing, whit many new functions. You can set Low Voltage cut-off to 3.0V per cell or even lower. You can use 52V battery with 48V firmware and have accurate SOC % reading.

We are sorry, this product is sold out.

What is the difference to K1 Flash
  • BB3 is connected between motor and display. Can be plugged permanently on your ebike, or you can just set parameters and then unplug.
  • Switch speed limits and configuration parameters by holding a Plus button on your Bafang buttons
  • Is waterproof
  • Power is taken from your motor
  • No firmware flash support.
  • ASLS function

Found out there is a new firmware for M500 - 18A CRX10NC3618i142055.9 - if anybody has this firmware, could you pls. share? Could be some new controller revision (bootloader and flashing protocol changed) as one customer was writing me he is not possible to flash old M500 firmwares into brand new spare controller.

Update: Yesterday I have managed to flash also M620 (only CAN bus motors) over K1 Flash.

So will be supporting also M300 and M420 as it is same firmware type. More over all these 3 motors have same boot code (which is strange) and even Besst allows you to flash M420 firmware into M620. Then of course you wont turn on your motor. ;)

Updated K1 Flash version 1.1 soon.

Hey Dado,

Are you able to program the DPC245 unit (Bluetooth) to be recognized by other devices such as a Garmin? Maybe there´s room to give this visibility at the GPS Head Unit (big maybe) to see battery levels, or even, stretching to possible programable interface like Mission Control from Specialized, distant future…...future hope. Wishful thinking

Cheers

Hello

That would mean to flash display with custom firmware. You wont get source code of bafang display firmware.

By retransmitting CAN to BT, would work.

BB3 does not have BT.
K1 Flash do have.

There already is some integration with the Garmin. My Explore recognises my M600 / DPC241 and somehow knows when the battery is down to 10%, showing a low battery level on the Garmin.

Within the Garmin features there are a number of fields you can look for and some BT integration with other devices. I started to look for how to do this and I think there was a thread somewhere about 2 years ago on this. I no longer use my Garmin Explore ( you can't move the map left or right to look for your route only panning in and out at which stage you can't see the tracks, so dumb ).

Hello guys.

Have managed a 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 Cutof). 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 maybe K1 BBR.

Sucking 20A at 29V ;)

Hello.

Unfortuantelly no. There is DC/DC up to 60V (up to 14S). Your battery is way above. :(
It is interesting this high power M620 controller modification - would say they had to change MOS FETs.

Ahh, bummer. Maybe on the FETs, I've read that they used 100V caps like the older controllers had too. I haven't had it apart to see.

Guys, did you know firmware M620 v41.1.02 is supporting FC1.0 parameters? So power adjustments are possible (missing Support level a.k.a Assistance %, I guess this only with new better torque sensor)

Since I swapped to CAN Bafang motors, I was concerned about power limitation (too soon - M600 from 30%, M510 FC2.0 from 25%) and about depth of discharge.

I did some tests of brand new K1 BlackBox Racing device and works as a charm. ;)
Possible to set Low Voltage Cutoff and you can discharge your battery down to 3.0 V per cell even without power limitation.
It is done with tricking the controller, not by a change of firmware, so device needs to be connected permanently to motor (over middle connector at the motor and hide next to motor).

Also you can use 52V battery with 48V firmware and you would get correct SOC percentage. (K1 SOC estimation algorithm will be upgraded if needed - not simple task to estimate correctly just from battery voltage. In cold it is very hard, when no battery temperature compensation).

Or you can use your 48V battery and flash to motor 43V firmware and you get cca 100W more.

Can show also battery Voltage at main screen (without decimals).

Device can also swap between 4 basic speed limit and circumference. (New motors - M510 FC2 and M560 - needs restart to take effect)

Some fake parameters: Current is motor temperature -640 means 64 degree C

LNT - Energy counter in mAh, is resetting automatically after full battery charge.

Hi Dano
I have 3 motors M500, M510 & M820, will K1 Flash work on all 3 motors and what advantages will I have over the Beest tool.
Do you offer a after Sales help?
I‘m pretty savvy with the mechanical and electrical stuff but clueless on the programming.
Thanks

Hello Goff.

Yes, will work with all 3 motors. M500 does not support much to set - only speed limit, wheel size and circumference though. But you can flash 17A firmware (if you dont have already) and you will feel significant more power.

K1 Flash is simple and user friendly, just connect to motor and wait few seconds for green steady light. No need passwords (which are expiring in Besst), no speed limit restriction (with current Besst you can set only 25kmh in EU or you need to hassle with python workarounds). And comes with set of firmwares (over 60 firmwares). Can run also rotor calibration.
Can not set old UART motors (but here it is cheap solution for 5 Eur with usb to uart convertor). And can not flash firmware to displays - but this is not much important, did not experience any issues with CAN displays.

Yes, you will get also after sale profesional support. Have 10y experience with Bafangs and did lot of troubleshooting with customers. Will provide you explanations, how bafang motors works, what is possible and what is not. :) I am fair and replaying in 24h usually. I am racing in marathon open category and tunning motors for higher power. Riding now 2kW Bafang Innotrance ebike, also 3.5kW LMX and looking forward for new M560 - what continous power it can stand. :)

Now working on "faking" battery device K1 BBR, which will allow deeper discharge and also remove power limitation - which was big drawback with non original CAN bus batteries. Also will be able to swap between 4 speed limits (25, 32, 45, 65kmh), calibration. Should be out soon. Later maybe also BT support for parameter settings of BBR.

Check the product link for thanks email. :)

Hello. I am a 36v m820 user. It is necessary to strengthen the BBR unit and walk mode, or add a throttle function. Is this possible? Is it possible to have it developed by special order?

Hello.

What you mean to strenghten BBR?
Not possible to add throttle support, or manipulate walk mode. You need to have source code of firmware, which you wont get.

Hello James, dont worry, I am declaring low value. So you wont be paying anything extra. Already shipped a lot of devices to UK. To UK expect 5 to 8 working days to deliver.

Hello. Unfortunately no, M600 is supporting only basic parameters: Speed limit, Wheel size and Circumference.

There is one firmware v46.2 for new M600 where is possible to set also power levels. But this firmware is giving first 2 seconds after start pedaling 500W kick. It all depends how it is coded in a firmware. Not possible to do magic with K1 Flash. :(

Think about switching to M560. Much better for setup, also better torque sensor behaviour. Only that noise... :(

I replace the M600 with a M510 with Controller 2.0 and Firmware 10.1. Pretty happy with it. I was thinking about selling the M600 or building another bike with it. But if it still not programable, then I will sell it.

BB Racing is A MUST HAVE for any M500/M600 owner. I am so happy of it. The speed limit adjustment is only one thing, but the best part is about the battery.

Now i can use my favorite super strong 46.7 M600 firmware and i can override stupid 30% power limit on battery.
BB Racing can override this and can get you extra kilometers that you may safely use from the battery.

If you guys are thinking about what you can get for your Bafang engines - then do not think much - get the BB Racing from @Dado (y)
