    Help cellman has a new 7t mac kit?

    Hello, Are you really happy of the services from Cellman from Emission-free.com? I emailed him a week ago for a quote for a kit + battery and he never got back to me. Even if he is really busy, a short acknowledgement saying that he is going to process my request would be the bare minimum. This...

    Clyte 408 maintenance issues over time?

    I have "only" 18,000km (11,000 miles) on my 5 year old 408. I use it year round and I had to change the bearings once and the hall sensors as well. Main problem is the water/humidity getting inside and damaging the magnets and hub. Over here in Ontario, the salt in winter just make things...

    Nine Continent Rear Wheel Dishing

    Hey, Just got my 9c rear wheel and as a lot of people I have this 10mm offset on the left. All the solutions I have seen are based on wheel dishing or frame spacing. I use a 5 speed freewheel and there is some spare space between the sprocket and the dropout so I was considering just...

    INFINEON CONTROLLERS FOR DUMMIES

    Hey, I am looking for the reference and where I could buy the connectors for my 48V Infineon controller. I have already replaced the phase and battery ones by Anderson connectors but I would like to keep the one for the throttle and Hall sensors. Thanks Fredo

    1000W BMC testing

    Just checked electric-bikes.com. They mention that their BMC V3 1000W is a S (speed) version. For my need, the T version would be more appropriate and I am still wondering is V3-S has more torque at low speed than V2-T. Anyone knows as well if a V3-T will be available ? Thanks Fredo

    1000W BMC testing

    Hello, I already have a xtalyte 408 hub motor I use daily, the year round, for my commute with temperature down to -28c (-16F) and I am pretty happy with it for the last 4 years. I live in a pretty flat area and speed/torque wise, with my 48V battery, it is perfect. But now i am looking for a...

    INFINEON CONTROLLERS FOR DUMMIES

    Hello, I have both a Xtalyte sensorless controller and the Infineon w/ the sensorless module connected to my 408. Both have the 5-pin CA connector as well. I have not noticed the glitch reported previously and my top speed is around 43km/h. The good things compare to the Xtallyte is a better...

    INFINEON CONTROLLERS FOR DUMMIES

    Your feedback is really appreciated. The Infineon is a great controller. I just tried the generative braking and was able to see my first Ah flowing back to the battery. When the speed wire will be fixed, I guess that for the cost vs features will be unbeatable. Fredo

    INFINEON CONTROLLERS FOR DUMMIES

    All right. I have divided by 6 the number I have for my wheel diameter and now the speed is correct on CA. I have kept the number of poles to 8 (Xtlyte 408). However, only part of my problem is solved. I re-iterate that with my sensoreless addon module, the infineon controller output pulses even...

    INFINEON CONTROLLERS FOR DUMMIES

    Hi Geoff I have the 12 FET version and use my 48V battery. In my case the throttle is stuck at 0% when I observe the pulse train on the output this is why I was wondering if the addon module does not send on purpose those pulses to know the position on the motor when no back EMF is generated...

    INFINEON CONTROLLERS FOR DUMMIES

    I am coming back to the this blue wire and the speed logic signal. I have soldered the sensorless addon I got from Keywin on my 48V Infineon controller. I do not know how exactly how this module works but it does not require the wheel to turn in order to start as for my sensorless Crystalyte...

    Two YESA waterproof LiFePo4 case, which do you prefer?

    OK thanks for the update concerning the internal resistance. It means that there are errors on the web site. The 30Ah cell is rate 20mΩ as well. See: http://www.yesa.com.hk/product_cells.asp?lb=2&id=3 http://www.yesa.com.hk/product_cells.asp?lb=2&id=1 Hope that this is just a typo! I...

    Two YESA waterproof LiFePo4 case, which do you prefer?

    From what Sam told me, Yesa makes a 48V/10Ah pack with YLH347094 cells. The Yesa web site gives the following specs: Dimension(mm): 34*70*94 Weight(g): 420g Standard Discharging: 1.0C Quick Discharging: 5.0C Max Discharging: 20.0C Initial Internal Impedance <20mΩ What I do not understand...

    Where is the best place to get this add-on board. I have sent a couple of emails to keywin last month with no answer. Is it a discontinued product ? Thanks Fredo

    lifeP04 48v 20Ah compare - Cammy Vs Ping

    Cammy proposed my to refund my pack if after 30 cycles, I do not get the claimed 12Ah. So I am going to return the battery probably as I prefer to spend $80 to return the pack than trying to fix something which is lousy anyway.

    lifeP04 48v 20Ah compare - Cammy Vs Ping

    Just a quick update concerning my Cammy 48V/12Ah battery. This is the initial plot: After 10 cycles, still 9.2Ah so no real improvment and far from 12Ah. Seems that all the elements are quite well balanced. After a full charge, each one them are at 3.8V. After a full discharge, all of them are...

    lifeP04 48v 20Ah compare - Cammy Vs Ping

    Hi, Sorry to hijack this thread as I am a little bit off topic. I received a week ago my LiFePo4 12Ah/48V comming from Cammy and have been spending my time up to now to put in place a testbench to evaluate the performance of the new pack. I am now able to dump automatically to my PC voltage...
