    Hello! As the title states I have one of those beautiful 12 mosfet controllers from ages ago.. a 48A 36-72V controller I recently repinned the hall sensor on it, though I cannot get it to run with the sensors plugged in or even in sensorless mode. 10 Kohms between all phases and ground except...

    making an EV controller? similar to bike... just bigger

    so I know people here feel like making their own electric bike controllers and I think this is a great method for getting the most bang for your buck am I correct in saying that I could make a brushless DC controller for an electric vehicle using different software programming and much higher...

    cycle analyst speedo not working

    So my CA speedometer isnt working anymore, its the sensor broken or what? Ive tried many different magnet positions on the thing, is it just a hall sensor in there? I think its ultrasonically welded shut though... I could be wrong.

    ok... so if I load my throttle too much at idle or while riding the controller shuts off and I have to reset the battery switch to get it to power back on. I have run this pack on my old 20A controller with no problems, its a LiFePO4 pack with a BMS but it can discharge higher than 2C and its a...

    brand new controller, does not work?

    ok so I recently bought a 48A controller, and I had a V1 throttle and it didnt work, got a new 4 pin throttle, still doesnt work. the motor is an x406 voltage is 53.4V LVC is set super low at 29V just to make sure its not conflicting anywhere. what can I check on the controller to see if its...

    48A CL controller uses 4 pin throttle? 3 pin throttle?

    soooo.... I got a 48A crystalyte controller... and Im thinking it takes a 4 pin throttle and not a 3 pin throttle like my old 20A v1 controller. I have a 3 pin throttle and its connected to it but it literally does nothing... anyone have any thoughts?

    a good lesson in machine shops - broken x5 stator

    Dont just let any machine shop press out your axle on your expensive electric bicycle motor. do they make just the center parts and how would I go about getting that out? this is a 5303 stator BTW

    shunts.... to solder or not so solder

    so I know the controller and my battery both have shunts... I have heard of this shunt soldering magic that raises the current delivery. so If I solder the shunt on my controller I should raise the available current from the controller to the motor? I have a 20A controller, soldering the shunt...

    new fets or new controller

    Sorry to repeat. I blew a FET in my old controller 24-48V 20A with a phoenix racer (dur) What will 4110 FETS do if I use them in my old controller and are there any other upgrades I can do to the old one? or should I buy a 36-72V 35A controller? Thanks

    blown FET, 4110 FETS and upgrades?

    ******************UPDATE*********************** So I blew a single FET in my controller, what would have caused this? What will putting 4110 fets in do? and what else can I put in (shunt, etc) that I can do to upgrade my 24-48V 20A controller... I know there are only 6 FET's in there which...

    Determining maximum discharge (continuous and peak) of batt?

    ok so I have a 48V 25aH LiFePO4 battery that I got from a guy. Its composed for a TON of smaller battery cells. Im trying to fixgure out what the current delivery capabilites are, is there any way to determine this? I know I should be able to get at least a 1C discharge from the battery...

    building a battery and I have a switch question

    OK so Im building a 48V lead acid battery for a project and Im looking for a toggle switch that I can use to turn the battery on and off. do I need a toggle switch that can handle the peak amperage output by the batteries? so say I drew 60A from the battery, would I need a toggle switch that...

    Borken crystalyte 406 motor

    bought a 406 motor a week ago, put it on the bike, the thing got me all the way to work great. One of the guys at work decided to take it for a spin and spin it did. it spun the motor around in the dropouts because there was no torque arm on it yet. I resoldered all of the wires but it still...
