    Infineon regen slip mode

    Hi, I have a ( Lyen ) Infineon 12 fet set to slip mode regen. It works well in that it does what it's supposed to by automatically regening when the throttle is disengaged. But it acts weird .. It's as if it's pulsing on and off randomly; it's not a steady feeling. As the throttle is...

    Mac 10T vs GNG direct to rear wheel

    I have been wondering for a few weeks now the differences in efficiency between using a geared hub motor or similarly powered single reduction mid motor ( not going through the detailer ) If using 1000 Watts.. And both the mid motor and hub geared motor have a 6:1 reduction.. How do they...

    Removing 10s from 37.7 v EM3EV batt

    For packaging reasons I want to remove a 10 cell segment from my 37.7 V 13.7 amp hour battery from Paul. I'm just not sure how the BMS works. Can I simply remove the cells and remove the wires from the BMS? Do I need a new BMS?thanks!

    Em3EV software

    Paul sent me his software but he didnt respond to my email asking why it doesnt work. Anyone know why the " Transmit Gauge " would just flicker indefinatley while I have the controller plugged into the computer. I have the right cable.. I've tried on two controllers..

    Pedal assist proof of concept

    Hi, I am making a proof of concept and would like to use an arduino platform to recieve two analog inputs and generate a V+ output to a Controller for use in a pedal assist system I've created. Looking to see if this is possible and advisable. My system would use the arduino to recieve hall...

    9C hall sensor/ wiring question?

    I just replaced all three hall sensors and the whole wiring harness. Multimeter readings ( from the leads on the sensors themselves ) Are the following: Yellow stays at 4.9v Blue stays at 1.8v Green alternates betweem 0 and 5v as wheel spins so it works fine. The yellow and the blue arent...

    CuteQ128 vs. 9C DD motor

    Hi, Ive been building a bike with a 24" rear wheel and currently have a 500 watt ( 9C clone ) trike motor ( not sure the wind ) from ebikekit.com. Its supposedly the slowest wind they have. 9 turn? Controller is Infineon 6fet at 22 amps with a 36 volt frame battery from EM3Ev. It's pulling...

    Bionx PAS System question

    I've been thinking about PAS ideas for hub motors and I'm curious about some of the existing technology. Does anybody know the rough concept or what method Bionx uses for their system?

    Infineon PAS wire harness

    I'm trying to identify the purpose of the two smaller black connecters ( right ) and the large opaque connecter ( left ) I recieved this harness from Paul when I bought his infineon controller and PAS display. I know the top is throttle Thanks

    Hub motor hall wire trouble shoot

    Hi guys, I have a rear hub motor from eBike kit. I'm trying to use one of Paul's 6 ft Infinion controllers with this motor. I had to cut the motor cable to access the hall wires so I could graft them to my controller. No matter what combination of colors I use the hub motor will not...

    Bafang BBS left second PAS sensor

    I wanted to hear from those who have Bafang BBS kit. Could i install a typical cadence pas sensor. Like this http://m.ec21.com/mobile/sDetails.jsp?offerId=10169165 Obviously it must go on the left side of the crank. It just looks a little cramped with the spacers and mounting bracket. The...

    Bafang BBS with Rear DD hub

    Hi, My basic idea is to use a mid drive for low speed and DD hub for high speed. Having 2 motors allows for the elimination of the dreaded derailer system. For now, ( since I haven't yet developed a controller to manage power between the two motors while using only one throttle) I'm just going...

    Infineon- Possible to program amps@ X volts

    Im using a bafang 750 watt mid drive and a rear 500 wattDD hub with a single battery Hub will use an infineon 30 amp controller from em3ev. Can i adjust the amps to volts curve? Im looking to limit the hub to low amps while the middrive handles acceleration. Then the mid drive will shut off...

    Ebikes ca proportional regen controller

    Ebikes.ca claims a proportional ( to brake amount ) regen feature.. That would be really cool!! Anyone have one or know how they accomplish it. It seams a some type of potentiometer would be needed in the brake lever? Or is it gimmicky marketing where they just offer you different levels...

    Where buy mxus/9c motor

    I guess I'm having trouble finding a hub laced in a wheel with a DD mxus or 9c type motor. Looking for a place that will have 24 inch. Em3ev no longer stocks them.. Wtf! Any suggestions. I want the slowest wind made and need a vendor who can confirm that that's what I will receive. Thanks!

    External controller magic pie 2

    Looking for a controller that will allow the best regen braking.. Would lyen be my only choice or does infineon have anything suitable? By best Regen I guess what I'm looking for is something that will have the most stopping power to take the effort away from my breaks. I'm curious if the...

    Methods to govern top speed

    Hi Guys, Can any of Em3ev's infinion controllers by programmed to adjust ( lower ) the hvc? Lets say I want to govern at 22mph, and I know what voltage correlates to that speed. Are these controllers programable that way? Other than the CA, how could I affectively govern top speed? Thanks,

    Em3ev triangle pack/ battery indicator

    Hi, I'm looking for a battery indicator only. Something literarily with only that function. Most I've seen on alibaba have pas settings and other things. My system is 50 volts using one of em3evs basic controllers. Any thoughts?? Also it seems a great idea if anyone is in the business of...

    Repairing a zippy flightmax 8000

    Hey guys, Firstly I'm not a novice but by no means a guru with batteries. In May of this year I purchased a flightmax 8000 for my custom built mid drive bike. It worked fine at first. But then I noticed my charger ( hobby people tazer charger ) which is probably a shit box started...

    Zippy Lipo 8000 with a BMS using just the balance leads?

    Pretty simple question really. So is it possible to plug something into the balance leads that functions to balance all 6 cells? and Can it be done practically?

    Pedal assist controller

    I am wondering if anyone out there knows of a good P.A.S controller for a mid-drive bike. I am looking at price as a criteria and am incline to go with an RPM sensor as opposed to torque. Anyone have any recommendations or experience with these? Thanks a lot!
