    how to program a sevcon gen4

    a few things to try - thanks guys. I dont have much info on the throttle apart from it taking 5v supply. I have it working now using the CycleAnalyst 5v supply so all good for the moment. Another question I have is that at 0rpm with the throttle engaged slightly the motor kind of hesitates -...

    how to program a sevcon gen4

    Yes the potentiometer supplies are fixed to 10v as I found out. Some later models have 5v output on pin 10 but my model - it is at batt +ve. The encoder supply is programmable to 5v or 10v but is already being used by the hall sensors. Might have to go down the regular path. Thanks

    how to program a sevcon gen4

    Hey all, Has anyone swapped a potentiometer throttle to a hall effect? The hall effect throttle supply required is 5v however I cant seem to find in DVT where to set the voltage. It is currently set to 10v for the potentiometer. Thanks

    Great thread. I have been tinkering with my Sevcon size 4 and Motenergy 907 motor. I have a few DCF and DLD files I can upload supplied from various parties if interested. I somehow convinced Sevcon to send me a license for my newer version DVT. This was good however I was a little short...

    MAC motor spluttering

    Hi Just asking if someone has had the same symptoms, save me time testing. My MAC motor has been playing up lately. It makes a harsh vibrating sound when trying to take off from a standstill, but if you pedal up to speed it works normal-ish... its faster than usual. It will be either like this...

    Nice electric/Gas tribrid Felt MP on Ebay.

    I like the frame and the look with fuel tank. I would prefer full electric but keep the look of gas tank and mid mount motor.

    Controller question

    What are the dimensions of the battery box? Are you using the stock battery? You said you were using 36V, just as an example you could use 6 x 6s 5Ah Lipo packs for 12s 3p pack which would be 15Ah and be about 150mm x 150mm x 100mm in size... which is a pretty small footprint...

    Controller question

    Nice bike!! Did you make this or buy? The battery box looks a decent size, I would think you could fit more than 12ah in there... What battery were you thinking of?

    Why was my SLA pack better then my LiFePo4 on the hills?

    Do you mean 3.3V? Should be charged to ~3.6V
