    Connecting the Cycle Analyst to a Generic Controller

    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...

    How do I switch on this SCR?

    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.

    How do I switch on this SCR?

    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.

    How do I switch on this SCR?

    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...

    The SB Cruiser : Amberwolf's 2WD Heavy Cargo Trike & Dog Carrier

    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...

    EM3ev Infineon Controller Regen

    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...

    Headway 10Ah cell problem

    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...

    Headway 10Ah cell problem

    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...

    2014 Electrical Systems-Close Call & Lessons Learned Thread

    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...

    Headway 10Ah cell problem

    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...

    rpm without load issue

    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...

    FINALLY RUNNING.....Not well.. any ideas? (video)

    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...

    What did I buy????

    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...

    Trying to ID this controller...

    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...

    Do lipo's need to breathe?

    True, but my controller programmer only allows LVC to be 3.5V per cell or even less :P

    Do lipo's need to breathe?

    Don't go believing that. My Nanotech LiPo batteries swell as much if not more than my Gens Ace LiPo's. Both batteries are about the same age, usage and C rate. Also, the Nanotech A-spec LiPo's don't seem to be worth the extra money as tested and reviewed here...

    It looks like this one: http://senyuancn.en.alibaba.com/product/895212532-200327007/Brushless_DC_Motor_Controller_for_Electric_Bicycles.html 48V 1000W 40A Apart from that, not much else you can tell just by looking at it. It might not even be the same. Open it up and read the voltage on the 3...

    How much weight can a x5 axle take?

    Not sure about that axle. The later X5 motors came with 14mm axles. I have one mounted to my 100Kg sidecar rig and it holds up just fine with about another 120Kg of rider and passenger. However I'm sure the majority of weight in the rig is spread between the two rear wheels, which are actually...

    Do lipo's need to breathe?

    I have several RC cars and several LiPo batteries which I've run until they can no longer provide the current I desire. Even hardcase packs will swell. The packaging is stronger and more rigid than your normal shrink wrapped LiPo batteries, but it still has enough flexibility to allow the LiPo...

    Controller: cycle-analyst plug / 2 black wires

    Teklektik already gave you the answer. The black wire nearest the red will be connected to negative on your controller, while the other black will be connected directly to the shunt negative. In a way, yes the battery/controller negative and shunt negative are directly connected together, but...

    Controller: cycle-analyst plug / 2 black wires

    I have no idea why your Cycle Analyst plug has 2 black wires. One should be white! I forget which one. Research the Cycle Analyst plug pinout online and you should be able to determine which of the black wires is the negative. I'm guessing it's the one right next to the red, but you better make...

    Help wiring BMS

    First of all, the positive (red) wire from your battery does not connect to the BMS. Just make sure of this. On the negative (black) wire coming from your battery, connect this to B- on the BMS. Then P- on the BMS goes out to your controller along with the positive wire I mentioned earlier...

    Controller: cycle-analyst plug / 2 black wires

    Oh and the shunt is usually on the opposite end of the controller board to the end in that picture you put up. The shunt looks like 1 or 2 metal bars.

    Controller: cycle-analyst plug / 2 black wires

    2 black wires? There should only be 1... Maybe my tutorial on connecting a Cycle Analyst can help? http://endless-sphere.com/forums/viewtopic.php?f=2&t=57591
