My FWD delta trike. Before: After: I'll create a thread showing the build eventually...

Hello there. Wow I thought this thread had died and it has been a long time indeed since I did this. I'm fairly sure I used all six wires. Red: Power Black: Ground Blue: Shunt - White: Shunt + Green: Throttle Yellow: Hall sensor Alternatively, you can connect the CA's yellow wire to a reed...

Yes, I believe the seller has sent me the wrong product. I pay $50 for an SCR and they send me a $35 diode. I shall contact the seller and hope they can refund me or send the correct item.

Yes, without the gate leads, this is just a big chunky diode and nothing more. Useless for what I require if it always on/off.

Hi guys, I recently received a SCR (model "KP300A") after a lengthy wait from the Chinese postal service to Australia. Here's a picture of what I expected to receive: Here's what I actually received: Can you spot the difference? It seems the thyristor I received is missing the gate...

My brother and I built a trike which broke in the end. It was intentionally broken after noticing a crack in one of the metal tubes. While it lasted it was such a blast to ride. A 25A controller running to a 48V 25Ah Chinese duct-tape battery powered a cheap ~1000W motor, propelling the rig up...

I eventually solved the issue. It seems that even with the regen jumper enabled, it wasn't enabled in the controller parameters. I'm not sure if it was switched off by default or not. My friends identical controller came with regen enabled, and yet mine did not. Using the Infineon controller...

Yes the BMS did shut off when it detected low voltage on the bad cell group. After a few minutes charge it allowed current again but quickly cut off the main power shortly afterward when the throttle was applied. However, I'm fairly sure I have worked this out. I don't know why one Headway...

Hello dnmun and thanks for the reply! The BMS was purchased separately from the pack. This pack was used in an earlier e-bike project, also as a 24S2P, but a different shape. The BMS wiring however, remains the same. The balance leads connect to the positive of each group of cells and the very...

My experiences: 1: Don't use the same coloured wires just because it's all you have lying around. Go out and buy/find some. I once used 2 red wires for my main discharge leads on a battery pack. I marked one with some black tape so I knew it was the negative terminal, but working in the dark, I...

Hello all, I recently put together a 24S2P (72V, 20Ah) LiFePo4 pack made up of 10Ah Headway cells for an e-bike project. It is connected to a BMS that has performed flawlessly in the past. After the pack (about 50% charged) was installed into the bike, the bike worked great. Then I charged it...

I have a similar LCD + Controller setup on 2 of my e-bikes. Here's my suggestion(s): - Within 5 seconds of switching on the LCD via the middle button, hold the top and bottom buttons down until you get into controller settings. - You should see a flashing number. This is the motor speed...

Just in case you ever need to work out hall/phase wire combinations, I found this months back on the endless sphere wiki. it has proved incredibly useful to me for connecting mismatched motors and controllers. http://www.endless-sphere.com/forums/download/file.php?id=69351 All 36 possible...

12mm wide on the flats would probably be a 14mm thread. Crystalyte X5 motors have a 14mm thread with a 1.5 pitch. Your motor could have the same thread dimensions. A thicker axle would be better IMHO. Just file out those dropouts. Take your time, try not to use power tools, keep measuring after...

To be honest all I did was Google "black Chinese ebike controller", scrolled through image thumbnails until I saw something similar to what you have, then followed the link to a page with some details :P No idea why the seller has masked the label on the controller. Perhaps images are for...
