Help debugging a Crystalyte immediate start 20 amp board controller

I've been reading multiple thread but could not find one that suggests anything I have not already tried. I have a Crystalyte 4012/409 hub and a controller for it. As a dual winding hub, the controller has a switch to determine which of the two windings it will use so its not built into the controll...

Re: Dewalt 36V lithium battery and eBikekit hub motor.

Any pics of batteries. What is the AH of the batteries.
is the motor a standard connector or is it one of those weird small round ones that e-bike was using for a while?

Help Diagnosing BMS failure

My BMS has failed (and took a headway cell with it). There was a broken sense wire as well so not sure if that cause it or happened when I disassembled the pack. Normally I plug the bike in every day (its my daily commuter). The bike was working fine before vacation but I left it unplugged as we wer...

Re: HuayuxinFeng Controller wuxing Trottle.. PAS Compat? LE

After a long of diagnosis I believe the LED are more than just a volt-meter and that the red-green combination was indeed a sign of LVC. The battery was fine, and I had been reading the status from leads connected to the battery which is why I though it could not be LVC as the battery showed 40+v. B...

Re: HuayuxinFeng Controller wuxing Trottle.. PAS Compat? LE

They're not very reliable. I've had LEDs in them pack up before. It's nothing to worry about. Oh thanks, but I would not care about the LEDs... The issue is that when it is in the red/green state the bike does not work at all. So I wondered what it is trying to tell me. Rode it into work and it see...

I have an bike kit I bought on craigslist. Have it hooked up and running but last week it cut out and the "three leds" (red=low, yellow=medium, green = high) showed only red and green (i.e. skipping medium) Does anyone have an idea what that indicates?

Re: How much friction in a Crystallite Hub? Overtightened?

If you put the old cover back on, does it still have the problem? If so, then something is wrong with the way the "new" cover is made, or spaced, vs where and how bearings/etc all sit on the axle/etc. You might have to add an internal spacer to prevent the cover rubbing on whatever it is rubbing on...

How much friction should there be in a hub? I know direct drive has more inherent friction, but I think my hub now has more than normal.
