    Reliable source for non fake cells?

    Hey folks, I took a long break from here after building my electric bike (which is kinda kaput for now) but back and bought myself an electric skateboard to fix which requires new cells (dead battery). Really looking forward to taking it out for some fun. It takes 18650 cells and I plan on...

    Ideas on ebike charging and use?

    Hi Folks, I have just partly rebuilt my ebike; I posted it in the builds section a couple of years ago but here's a pic of it now. I changed the motor from a rear DD golden motor to a golden motor mini, 36v front mounted unit instead. I wanted to reduce the weight and also be able to pedal the...

    Please Help- Contol and Motor questions

    Hi Folks, I haven't been on the forum for some time; I have been working on my own piggy back controller for a brushless permanent magnet motor and I ran into a couple of things. I think these are fairly simple questions to answer for folks in the know. So I have two test motors, both are made...

    Hall sensor positioning

    Hi folks, photo attached on where I think I need to add hall sensors to my motor. You'll notice further out from these points are some other sensors, these are the original commutator sensors for the motor that I cannot use. Thanks!

    ESC issues with large vehicles and brushless motors

    Hi folks, After my success with my ebike (900 miles and counting!) I want to move on to something larger. I've been doing some background reading and formulating some ideas but I have a question about electronic speed controllers for brushless motors I hope someone can answer. As I understand...

    Golden motor controller internal pics

    Hi Folks, I remember seeing some photographs of the circuit board(s) inside the golden motor 'cruise' or 'magic' controller. However many searches have proved fruitless; does anyone have these or know where they are? Thanks! :D Edit: here is a pic, and I'm assuming the backside of the same...

    LIPO open heart surgery (worked, but be careful)

    I had a bad cell in one of my zippy flightmax 5000mAh 6S packs, so I bought a 2S 5000mAh turnigy pack from ebay with the same C rating to repair it. When I opened up the pack with the bad cell it was obvious which one was bad, it had slightly ballooned (marked with black sharpie in photo). As...

    Is my lipo doomed?

    I got a batch of zippy 5Ah 22.2 lipos and two of the cells have these swirly white markings on the pouches. I took a photo. Are my cells going to die? I have cycled them once and the voltages are all fine. Has anyone seen this before? :(

    Regen question

    I searched and didn't find an answer to this question: I have a golden motor 36 volt 750watt hub motor and use it with a golden motor cruise controller with regen capability. My battery pack is 12 lipo cells in series, around 44.4 volt or so, 10ah. I was intending on adding the regen switch to...

    Confused about throttle control options

    Hi Folks, I have a 750W golden motor brushless hub motor and golden motor cruise type controller. I tested my setup on the benchtop by putting the +5v feed through a pot and giving the controller a voltage signal (I'm guessing the golden motor controller works via a potential divider?) However...

    Newby ish battery capacity question and range.

    Hi Folks, I started putting together an e-bike a while ago and got distracted (baby/business/job etc) but now I'm keen to finish it off. I got so far as building up a wheel with a 750W golden motor hub rear motor and a golden controller with regen. I tested the setup with a benchtop PSU and it...

    My Hybrid E-bike project

    Hi folks, I'm pretty new to the forum, a bit of background first: I've been toying with some kind of assisted bike for a long time, going back to when I started working on a folding bicycle with a hybrid gas/electric drive system on it, it was to have a microcontroller controlled 22cc motor and...

    NiMH options?

    Hey folks, I am pretty new to EV bikes, I'm putting together a nice commuter/cruiser with a 750W goldenmotor rear hub motor and cruise controller currently. I'm going to use it to commute to work which is 7.8 miles away, I can charge up at work when I get here, I doubt I'll be running pure EV, I...

    Newb with some fitting questions

    I did some searches but couldn't find what I needed. I just got my new golden motor 750W rear hub motor and cruise controller, I hooked it all up tonight to check it all works (and it does) and dropped it into place on my bike upside down. I am unsure of a couple of things. It has two long...
