The unfortunate thing is I bought a new controller to find all this out!!! But maybe Herve can help you with this, I hope he/she can respond to you. Make sure to always make a back-up of the factory settings. But no connection to Bafang controler. So I dont really see anything that you could do to fix it. And what display are you using? So I tend to do this less now, therefore my drivetrain also lasts longer. The BBSHD uses a cadence sensor. Questions: controller programming part is broken kindly elaborate, not sure if its a physical or software part, is it external to the bafang controller or inside the controller. I want max available throttle but still VARIABLE on all PAS. Can I keep the other suggestion values that you recommend in this post to improve my experience of riding, I usually use my bike for mountain terrains. Maybe somebody know the answer to my problem. So there isnt really a setting that you could change that would solve the issue using the programming software/cable. (sorry for the second message I thought the first one wasnt posted). Ill see if I can find an accurate gps speedo and match of up to that. Max current: 28A, If 28A is written on the controller, this will be the maximum. Stop increasing when you feel that the power becomes to much for your bike to handle. This morning I used your instructions to reconfigure my settings. A programming fix is finally available to address this oversight. Turning the battery off and on instead of replugging it, shouldnt be the issue. I probably Will order an other Bafang controller if I have to for now. And even it goes it can stops at any moment. The stock assist levels differ even more from seller to seller. Is there any remedy? The heavy load on the motor indeed could have caused some problems with the controller. A wrong sequence also should not cause a controller to fail. I just reprogrammed my controller so I need to test to make sure Im getting the correct power levels assigned to the 9 modes. I would like to know what settings are needed to protect the controller and provide optimal performance when using a 52V battery. So, to my knowledge there isnt anything available for the M500 unfortunately. 09-01-2019, 08:38 AM. I am glad you were able to fix it! I am glad you like the firmware! I do use a gear sensor. Error code 30 could also be caused by a faulty controller or display. In general, a full 18650 has a voltage of 4.2V @100% and a voltage of 3.2V @0%. So in that case, the 52V, will be the only option. If you want some specific settings like you mentioned, you will have to create custom settings. My engine is 350W and 36A of batterie (everything is the same as before). Needed for crossing busy streets. And if they are not willing to ship one out for free, they might be able to reduce the price of the replacement. You are right! If you want 5 stages, you should still fill in the 9 assist levels, I believe it picks assist levels 1,3,5,7,9 as the corresponding stages if you choose 5 stages. Tuning the Bafang Controller with UNLOCKED firmware - YouTube I intended to use this on a touring bike. No worries, I will always answer all questions! Yes, everything works fine but the settings are far from perfect while set to default. And that when the percentage of battery shown on my controller drops to 41% it will stop assisting? Assist 5 100/100. Im having trouble getting started. A fully charged 48V battery would he 54.6V. Also, what are the stock current limits on the 0-9 assist levels? Yes, the speed readout would be nonsense, but the rest of the motors performance?? stc-isp-15xx-v6.86E.zip 20 inch wheels are rather small, the smaller your wheels, the less top speed. If usb driver is installed correctly the software will find the the com port. This way I send the serial data over USB via a raspberry pi. Alvast bedankt, Luc. So you will be stuck with the factory settings. Best regards. Therefore it could be possible that you destroyed your IGH with the power of the BBSHD. Unfortunately your e-bike cannot be tuned. So if you look at it that way, it isnt weird that the cadance at those speeds will not be optimal anymore. So riding along in too low of a gear in the effort of increasing efficiency will create the opposite effect since you then will not be able to put in your own leg power. Shows Time, Power Assist Level, Trip Distance, Speed. Like are all wires connected properly. Im new to the E-Bike Kit and have purchased a BBS02B, 750W and 52V battery. Connect With Us. My screen have always been set to 48V. Hi Giel, that is correct. Upon receiving this built bike from the company, I was stuck at 15mph. PAS input will cancel throttle input, causing a sudden and undesired drop to 0% throttle. But if you want more initial power, you can definitely increase this, especially with a BBSHD. I have the cable provided by Bafang that I connect to the display cable as described, I installed the x64 win10 version of the proposed driver. If you follow the steps, it should work.

I have a Victesse bike with a bafang M400 and a 36V/10.4Ah and 374 Wats. So when searching for a battery you should look at the Wh specification. No display/ no throttle. This way you can have the bike on, without the risk of it applying power. Since with that much power you can easily strip gears when you dont select the right gear. I would like to know which motor you have exactly and which display. If you set this to a higher value, your bike will have more power. It looks like the motor max rpm is roughly 135. There is also no fooling around with com & serial port configurations in order to get it to connect. Hi Dima, I am having the same problem. Hi Giel. 1 Tommycat commented 03-14-2021, 05:26 AM to use Codespaces. Make sure that you set the designated assist level in the throttle handle tab to 9. But this way you can have PAS 1 as the no power setting on startup as a safety feature. Since day 1, when using PAS, intermittently my chain wheel loses all tension causing the crank to spin about 180 degrees before the tension comes back. So if you want full power, you can set it to 15. To my knowledge, its not possible to program any other motor than the Bafang mid-drives. Is something corrupted? Your speedometer will then still work like it should. Now you should see the program, showing three tabs, "Basic", "Pedal Assist", and "Throttle". The range is dependent on so called watthours (Wh). Basics of programming BBS02 and BBSHD mid drives EDIT: heres a pic of a bafang usb-serial cable: If you search on m400 on this page (CRTL + F), you will be able to find his comments. 54.6V corresponds with a 100% full 48V battery. Greetings I have installed your configuration and Im enjoying the ride. I will consider it! If not, can you tell me the setting changes Ill need to make? Im looking for sites or people who have reprogrammed this engine or bike. Endless Sphere SOLVED! To clarify, do you have a bafang hub motor or mid-drive? This cable and software does not work with the Bafang M420. Im happy with all my setting, but which one do I change to tell the motors controller that I have a 52V 17.5Ah/910Wh battery? UPDATE: The BBSHD is programmed in the exact same way with the same software as the BBS02. Hi Giel . The higher you set it, the more power it will give initially. Will try the software from your link later this day. So you should attach it to the 26 wheel, or set it at 20 in the settings. So keep in mind that displayed percentage probably is higher than the actual battery percentage. It sometimes help to try another computer, but you already did this without success. I recommend 4, because this is a nice sweet spot. Thanks Zeeshan, ill give that a go and see how i get on. I think you are not reaching higher speeds because of your gearing and wheel size. There isnt any graph released of Bafang that shows RPM (cadence) vs efficiency, therefore its hard to say at which RPM (cadence) best efficiency is reached. The debate is launched on this configuration and / or the ETH1861 with M400. I hope that this explanation is clear to you. The speed limit is overwritten by the throttle, so you will go as fast as you want. Unfortunately, I dont have the knowledge nor experience with serial communication methods to help you. Have a good day all. thanks The lower this setting, the faster the drive unit will decrease power as you pedal faster. I would suggest reading about the error online and trying all the mentioned possible fixes. I used the same cog for all the test. BBS02A - No idea, not tested, not recommended to try unless you have an already bricked controller. So do make sure the current limit is set to 30A.

I have a bafang 750w mid drive motor and sometimes the motor dosent stops after i stop pedaling. I think that the motor turns at maximum speed, but because of the gearing and small wheels, 24 will be the top speed at those gear ratios. The 3 prior steps had me disconnect the cable from the display, so the button on my handlebar no longer turns on the bike and my computer sees nothing attached at the port receiving configuration cable. I would suggest trying yet another pc and trying to install the drivers again on the pc you already tested with. There are a couple of things you need first to program your Bafang Controller: 1. So leave it to default which is undeterminated. If you apply these settings you will have the closest thing to throttle-only mode in assist level 0. 17- power on battery I have built many custom pedal bikes over the years and know a few things about bike building. It also is not too responsive, which is good. Using This Software Can Void Your Warranty! Then it will drop to for example 80 percent of the current that is assigned in the selected assist level. I have a 36v 500w bafang mm g340.500 07 motor. 3/64/41 It is more difficult and advanced than this. I recommend 36, since this is the default and in my opinion, works perfectly. I am away from the bike at the moment. All the settings are the same but the software that Penoff has written fixes . This is absolutely normal.

Ein Kabeladapter von Higo F auf B hat nicht funktioniert. Error code 30 can be an hard error to fix, since it is not always clear which part is causing the error. If it would be tight, it would be unlikely that it would lose tension while using the pedal assist. To my knowledge the egg rider basically does the same thing as the computer software. Thanks for your detailed explanation on your problems. If the bike then still functions properly, you know it uses the levels 1,3,5,7,9. I hope you figure out another way of fixing it. It that case it will be really hard/impossible to damage the motor. So if I dial down the current to say 15 amps will I increase range but maintain torque? furcifer 10 kW So completely wrong. But in practice this will mean that your useable range will be less. You unfortunately dont have this motor, so the cable will be useless for this motor. Hi Herve, and Geil, You ofcourse can always try a different pc, to see if this makes any difference. The Bafang motor is however already internally geared so that it can operate at higher RPM. So it makes sense that you controller is limited to 28A, this is completely normal for your controller version. Here is my configuration, bike: 26 in full suspension mountain bike (Kona Kikapu Deluxe, oldie but goodie) Can you help me with any suggestions?
