battery: 52V 13AH You could set the current limit to 18A as well, depending on how much power you will need. Firmware version: V 1.0.0.4 The debate is launched on this configuration and / or the ETH1861 with M400. Using this cog I put throttle to max. The voltage level of the battery goes down nonlinearly, the software of Bafang converts this to a battery percentage level. BTW, all color displays do NOT have 9 levels of PAS. A bad connection, incorrect connections, etc. Baud rate, etc? Check if you have the same issues there. This could be the reason for the error code 30 as well. Avec cette configuration, encore quelques soucis : -coup parfois, et difficults de relance de niveau 2 3 voir 4. Many thanks for your reply! It indeed is a mistake of the previous owner if he set it at 26 in settings, but attached it to the 20 wheel, this will not work correctly. Yes, you could lower the controller maximum current. You can even destroy the controller in certain cases. Thanks Steve. Therefore leave it at By Displays Command, then it will be the same as what is set on the displays settings. In general, a full 18650 has a voltage of 4.2V @100% and a voltage of 3.2V @0%. Back on the road again and all going very well. ONLY CONTINUE IF YOU ACCEPT THE CONSEQUENCES OF YOUR ACTIONS! I recommend setting all the Speed Limit [%] to 100%, this way the motor will only stop assisting when you hit the max speed that you set on your display. This allows you to work with your saved profiles even if you haven't connected your bike. Thank you and good day. Subscribe to our newsletter and stay up to date! Its strictly a feature of the mid-drives. Like you Im knew to this setup so if you ahve any tips feel free to share! kan iemand het mij vertellen. Again, good luck, I hope you are able to fix it! display controller: 860C, The 860C has a setting for me to change the voltage to 52V (nice). You then cant change the speed limit on the display of the e-bike. Ciao Jim, Do you also have any suggestions on small front chainring? 4. Are you using a 4K monitor? So would definitely give that a try. The Bafang motor is however already internally geared so that it can operate at higher RPM. The only thing you should change is the low battery protection. But getting the exact same settings on there as the old controller is definitely something that you should try first. The level 0 is meant so that you can have the bike on, but without pedal assist or throttle. But most of the displays wont be able to do this. I bought the M620. I tried the throttle going up a relatively steep hill and could hear and feel like the hub gears were slipping. If Bafang would fix this, it would be an absolutely near perfect motor. Thanks for the suggestions. You just pedal along in the assist level that you find that gives enough assistance. SOLVED! Thank you for your useful information. Is this correct or should I change it to 26 or leave as is? Order Number. Thanks, Only at really low current limits this could be a problem, like explained above. I found that this way the motor responds a lot more like you would expect. So if either of the above gives you even the slightest hesitation, stop reading and go ride. Could you please tell me if this is how it would work, or what should be changed? The battery voltage to battery capacity differs a lot between different 18650 cells. I do use a gear sensor. That means motor is consistently wanting to help until it reaches steady 90RPM witch is 20mph but it never reaches 20mph because biker is happy cruising at 60RPM. If something goes wrong you can always return to the default settings. It is by far the best setting I Oui jai reprogramm mon velo de trekking (Fischer ETH1861) avec le logiciel. So this, in fact, will be a limit. 16- reconnect LCD to bike Current A was 20A If it says 40%, the battery often is more like 20% charged.
