    Razor E300s upgrade

    Got a good deal for this scooter on Craigslist. The motor barely turns unloaded, I'm guessing the SLA battery is likely dead. Planning to use 10s6P Panasonic 18650PF at 36V, which can easily fit in the case. Replace the front wheel with a 10" BLDC ungeared hub motor. It's going to be built for...

    A front suspension fork made for a hub motor

    For high W, telescopic forks won't last as seals, dropouts, etc. gets damaged. It would be able to handle the same amount of power as a rear hub(mxus, cromotor, 54XX) setup. I haven't seen one that exists, so planning to make it. I have seen a while back of an ebike where the fork is made...

    FAULTY 18FET 132V Infin. controller from Lyen, FAIL on 106v

    Ruled out hub motor - tested halls and runs smoothly on another controller. Ruled out any loose connections - halls and phases tested for continuity from board to motor connectors. I plan to use the controller for my bike's switchable 16s2p / 32s battery pack configuration. I had him mod the...

    18FET 84-132V Infineon controller from Lyen - poor quality

    I opened it up the first time and saw some melted solder on the capacitor casing and also on the board below it. Some areas on the casing's skin as shown in the pic is cloudy and wrinkled and has a rough(coarse) feeling - not the normal clear see-through and smooth texture. Capacitor's max...

    16s bms wiring - needs verification

    Got this a couple of years ago and plan to use it for charging only. I can't remember exactly the wiring. There are 18 balance pins and shows the last 2 are connected for cell #16(+), I just remove one of the ridges of my 16s balance connector to make it fit.

    What's new with the Bafangs?

    Hello folks, I'm considering on using a high speed wind Bafang for the front to prevent overloading a 9c on the rear. By reading some threads that this have "motor codes", to identify a motor's winding count(higher # equals slower wind), but when checking bmsbattery.com, there is no mention...

    Need advise on configuring Lyen 18Fet controller

    Is there a way to read the settings in the controller as what the Kelly config program does? There are 2 Keywin parameter programs(Parameter Designer For 116.exe & LYEN-EN.exe), which one is preferable to use with this controller? I'll be using either windows Vista or XP if that matters.

    Throttle cable to Food thermometer to motor, controller, etc

    The thermometer is a Maverick wireless redi-chek. Besides using its beeper function, the plan is to wire the throttle cable as such, that when the alert temperature is reached, it will pull down the throttle signal. The question is how?

    Kelly KBL controller to 9c problem

    Tried all 36 wiring combinations, not one has worked as expected, i.e. smooth motor running and low 3A or less current. Some behaviors for configurations that were able to turn the motor forward: - loud and blew my 4A fuse - While at the lowest 10% throttle and holding, the motor ramps up as...

    Microwave oven as discharger

    Curious to know if anyone has tried it? Will it run on 72v? Could it be depending on particular brand/model... When its power level is set to 70% and by monitoring with a KillAwatt, power outputs between 750W & 1100W which is similar to an ebikes power usage. This can be useful when: -...
