You could check this by setting levels 2,4,6,8 to current limit 0. If you are pedalling or using the throttle doesnt matter, it will increase the top speed in both cases. In general: yes, you can use a 52V battery with an 48v controller/motor. Could this be caused by an issue with my torque sensor? BAFANG | Downloads So Ive set 78% for max speed of all PAS and used your suggested % for current limit. The missing files can be found here: Thankyou, these files have been added to the Download package in the post above. Thanks for your efforts on this.

My bike has another issue, so I havent been able to test it. Then it will drop to for example 80 percent of the current that is assigned in the selected assist level. This will only be needed if the motor is very old or used a lot. Many thanks for the help. Have you increased that already? If you have read this entire post, you should have a good understanding of all the settings there are. However, I think I know what youre maybe going to suggest is it to change the chainring?

Its my first ebike, i rode more than 2000 km since April, but last time I every day rode 500 m abt 20% uphill on level 6 on the throttle on 34 cog, maybe this is the reason. If all those fixes dont work, it could be that the controller is simply broken. So leave the low battery protection unchanged and set the current limit to 18A. 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. The range is dependent on so called watthours (Wh). I saw videos with the same kit, but battery with 17ah, 13ah, doing more then 100km range. Thanks a lot, really appreciate it! 5 levels is just an awesome balance between controllability and practicality. I click on Connect, I accept the terms, the Disconnect button activates but no link is established from the Read Flash button does not activate.

I found that this way the motor responds a lot more like you would expect. 9/100/100. Thanks! If this doesnt work, there is no option to deactivate the PAS in software. I hope this gave you a better understanding about bike gearing and cadence , Hello Nominale voltage: 48 52 A 10.4Ah battery is quite small and unfortunately doesnt give you all that much range. Display motor/controller temperature (shown in range field on display). You cant just lower the current and get the same power, this is physically impossible. When we ride with PAS what gear should we choose: as we usually do without PAS to ride with cadence 90 or more or less to get maximum efficiency from the motor? This behaviour can be normal, because when you accelerate, the battery voltage drops. I am not 100% sure though. Anyone have a photo of what the display would look like with this firmware, maybe even with a bafang 860c? Compare this speed with the speed on display, if they are within a maximum of 5 km/h difference, its all set correctly. So the difference is only in the motor controller, they did some improvements. I recommend 4 because this results in a responsive system. Thank you and good day. You are using an out of date browser. When I accelerate the speed decreases after a few seconds it is not constant even if I keep the acceleration on and makes a noise as if the engine does not have enough power. If you want it to be around 350W, set it to 10A. Hi, Problem Im able to connect the USB cable, it shows on the configuration programs as COM3, I hit connect it shows connected, but the Read button is remaining gray and no info is coming from the controller. Hi Giel Before updating the firmware, we need to verify that your motor's microcontroller unit (MCU) is compatible with our firmware files. Lol You can simply use the suggested settings in this guide. 32 or 64 bit? So if you just select a lower assist mode, your current wil be a certain percentage of the 18 amps (3 amps for example in assist mode 1). Current: 30A And this is how it works: Bafang BBSHD Firmwareupdate 52V Watch on Customers also buy Customers also viewed TIP! I would try to follow the same instructions on another pc.

You may have one of the following problems: You dont have the necessary usb drivers installed. Thanks for your attention. Install the software and driver on a different computer/laptop. I know you stated that under the throttle handle you should keep start current [%] to 10, i would like to know if 15 is too much for my set up and also if switching to speed mode instead of current is safe for the BBSHD. Disconnect the display cable on the bike and plug in the programming cable with the green Higo connect to the connector you just unplugged. The reason why it doesnt show up on your computer has probably something to do with your drivers. Im using a laptop with windows 7. Thats why your motor will only work at this voltage. It can be bad if you wont pedal at all and let the motor do all the work with the throttle for example.

Bafang BBSHD Firmwareupdate 52V - YouTube But Id like a 5 PAS setting from 15 to 60 km/h. It looks like the motor max rpm is roughly 135. As far as I know, there isnt a proper way to get only throttle working in assist level 0. By setting all the other assistance levels (0-1-3-5-7) to 0 (zero) the controller works perfectly and selecting the 5 assistance levels from the display changes the motor rotation speed. Kind regards. Again, good luck, I hope you are able to fix it! Your display can be set to 48V volts. you said the max for BBS01 was 15A. There is no MAX PAS in the setting. They said I could reach 27 and so far I cant get there, but to 24 tops. At what cadence the motor works more efficiently? Yes I know this is an option, however I ordered this combination because it was offered and others report it working as designed. So the max current should be 13A. Therefore it will just reach the maximum RPM possible with the set current. Who wants to lug their laptop out to the bike or vice versa? If I hadnt gone through the trouble of making gaskets and siliconing in the new controller Id be tempted to give this a whirl. Pour ma part je lai fait, mais je recherche partager lexprience avec dautres utilisateurs. 9b- Disconnect ebike battery from BBSHD Thanks a lot for this awesome guide.

TommyL, Hi Giel, Just to update you on 2) I would be curious if I can just use my 52V battery and change the controller to be at 48V system? Now click File in the left top corner of the program. Send OEM-Area Products; Connect usb to computer and open up software (3.54 MiB) Downloaded 1033 times motor power without pedal or throttle input).

P.S The egg rider might work, but I expect it not to. ONLY CONTINUE IF YOU ACCEPT THE CONSEQUENCES OF YOUR ACTIONS! This works so far and the speed assist level is being set correctly! I am a little confused about why your controller isnt 30A. The speed limit of the throttle should be equal to the speed limits assigned in the basic tabs.

But external controllers are always possible, but this will be extremely DIY, and not convenient or clean at all. The Current Limit [%] setting specifies the percentage of the current limit[A] the motor can use at that level. Thanks! Die Mglichkeit, dass Sie etwas braten, ist dann ziemlich hoch. Herve So if you really want a smaller size, I would recommend 12-14Ah. Hope this helped you, if you have any further questions, let me know. When the display tells you the bike is at 40%, it could actually be at 20%. I can find no explanation about the difference between setting the Current Limit to 0 or 1. 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. You are right! The only option is buying a replacement controller: The idea it to save more battery power by having the motor run as if the battery is a 48V battery. I am glad you were able to fix it! Hi Giel. elaborate it further? It could also be that another setting in combination with the current limit is conflicting. Hii!! You signed in with another tab or window. Hope this helped you. My kids both have legit mountain bikes as well. The reason why your new controller feels slow, is probably because the current limit is set lower. Can I still set the Speed Limit to 100 without straining the controller? 25 amp upgraded IRFB3077 mosfets controller (up to 1300 watt with 52 volt battery). Add option to show current temperature in speed field on display while walk mode is active. Are the LEDs still lighting up on the usb programming cable? Your story about the RPM isnt completely correct. It only works with the BBSxx line-up. In general, a full 18650 has a voltage of 4.2V @100% and a voltage of 3.2V @0%. Or only when you are really pushing it? So next I set my max speed for my display to 45 kmh.
