Hello everyone, if you have a 48V 750W motor, is it possible to limit the power assist mode to 250W? So that you are legally OK in the EU with max. 250W and 25kmh? Many thanks for your feedback!

This is the battery specification: HAILONG-PLUS 48V 12.5AH Specification: (Include 2A Charger) The battery pack fits 48V 250W/350W/500W/750W motor,If your motor power over 750W,we can't provide warranty for this battery Rated capacity: 12.5AH 5P13S Li-ion 2.5Ah 65 pcs 18650 battery cells (china...

Sorry, this is nonsense in my opinion. For the Wh you mentioned there is a separate field in the Parameter Configurator and it is calculated from battery voltage x capacity in Ah:

Hello all, For a 48 V 750 W battery, what value should I enter in "Battery power max (W)" under "Basic settings" when using a 500 W motor? Thanks

The reason I ask is that I have seen that when I turn off the battery switch, the kilometers are not stored correctly in the display. The next time I turn it on there are a few missing... what could this be? I have turned off the odometer compensation because I do not use the data display of the...

Can you please explain this a little better? What do you mean by "battery sw" and "BMS"? Thank you

Can anyone tell me if it is necessary to turn off the Hailong battery with the red power button when the bike is not in use? Or is it enough to turn off the VLCD5 display? Thanks

I have the latest version, so it should be the C2. I am doing well with it!

Why do you need extra sealed bearings? Which ones? Do you have a link? I have only done the thermal conductivity upgrade with silicone pads...

Forget stock firmware and ST Link software, you just need it to test if the USB connection is working properly. You need just the Emmebrusa Java UI tool to set all needed parameters, I flashed it already plenty of times always without any issue. A couple of hints: disable "Street Mode" set at...

I also had problems with the speedometer not working when I had "odometer compensation" enabled. Try to disable it, then it might work again. In general, I have disabled the data display in VLCD5 and the parameter configuarion as well as it is quite confusing as to what data is displayed. If I...

Today I made a tour with 25km and about 750 meters of altitude. I have a 12.5Ah 48V Hailong battery. Before the start, the battery was full except for one dash in the VLCD5 display. After arrival just two dashes left. I mostly drove with level two in hybrid mode, which I configured with 150 in...

Wow, thanks for this detailed explanation! So I'll get me something like that https://amzn.eu/d/2gRUsKJ according to these instructions https://github.com/OpenSourceEBike/TSDZ2_wiki/wiki/How-to-improve-motor-heat-dissipation to make a good contact to the housing as the next optimization. Is...

I have set the max amps back to 12, as specified for 48V. I also reduced the max on turbo to 450 instead of 500. I did a small tour with quite a climb, pedaling between stage 2 and 3. When I got to the top I stopped to see how hot the engine was. It was very slightly lukewarm.

Understood, thanks for the advice! Can you give me some advice on what percentage of the maximum value is safe in terms of overheating? Thanks

Now everything is perfect. The default values for the various levels were set much too low. Have now set them in turbo mode to the maximum value. A brute difference!!! Top!

To be honest, I am a bit disappointed after the first impression. I have set the Hybrid Assist Mode. There is not much difference between the four levels anymore, not like the stock firmware. I also feel that the stock firmware had more power at the highest level. Can this be? Or maybe I have...

Can anybody share the best settings for a 48v 12.5Ah battery? For MTB with good climbing performance. Thank you!!!

Update: everything solved. Two cables were connected incorrectly. Programmed everything like a charm. Will see if the open source firmware is that much better than the standard firmware.
