    Motor Cooling Ideas

    I'm curious as to how some of you cool your motors. I'm using a custom motor based off a highly modified mag motor s28-400, and overvolting it. It already has a large heatsink that sticks out into the airstream, but my main issue is after I stop moving, and the heat soak saturates the...

    Fechter's current based throttle

    mukeshp11: What product are you referring to? And I hate to bring up an old thread, but I've got the same questions as Geebee...wheres the final design? I've actually been talking with my buddy about building a similar circuit to this, but I feel that Fetcher has redesigned this much better...

    Added LED to throttle, now it wont stop

    finally got the rs232 to controller adapter from kelly, and it programmed right up first try. bumped the throttle up to 30%, and cruise controls gone! my new throttle just wasnt 0-5 stock. To clarify, programming fixed this problem

    Added LED to throttle, now it wont stop

    Heres a really crappy picture inside the throttle. I dont know if this will help anyone, but maybe it will make something more clear. I called Kelly and tried to figure out how to connect it, and was informed I need the controller to rs232 adapter, which they promptly sent out. Hopefully this...

    Added LED to throttle, now it wont stop

    im pretty sure there is a way to adjust the throttle range through programming... are two of the programmable parameters, and the stock ratings on the controller. I'll try it without the LED tho, and see if thats causing it Edit: I just tried it with the LED removed, and its still doing the...

    Added LED to throttle, now it wont stop

    I recently purchased a new 48v with battery meter thumb throttle, and added an LED for the status of my controller to the throttle. In an attempt to do this cleanly, I spliced the 48v wire into the power switch(inside the throttle), and used the power switch wire as the 48v wire, freeing up the...

    Kelly KDS48200 setup

    i think it was actually a battery issue. I put in a less powerful motor, and it was still quick, but didnt pull as much on the batteries, and seemed to be alright. I still havn't been able to program the controller due to the crappy usb adapter, and lack of rs-232 on any of my computers. I found...

    Kelly KDS48200 setup

    I've run into a problem, and was curious if anyone else had done this. As im riding, every once in a while, the motor will make a chuffing noise, and the back tire temporarily locks up..usually under decel..at 45 this is not good... My only guess thus far, is that im discharging the SLA's...

    Upload Your Circuit Schematics & Requests Here...

    This is probably really simple, really bad, and has been uploaded before....but Heres my schematics to run the Kelly KDS48200 at 48V with SLA's edit: its based off of the schematics that kelly provided, but with a circuit breaker instead of a contactor....its essentially a simplified version of...

    48v Throttle from Kelly

    4S1P 12V 12AH SLA's @ 48v, 55.5 freshly charged. No readings for when the batts are low :( I knew there would be voltage sag, and with my old controller/throttle, it would do the same thing, but it would also give a much better idea of what kind of battery life is left. as it is now, when my...

    Kelly KDS48200 setup

    This is my first major EV project, and I need a bit of help on the controller setup. I've been doing a bit of searching and havn't found a whole lot on the setup of these kelly controllers. I've drawn up a schematic based off of the ones supplied by kelly, but will need some help. I've attached...
