Troubleshooting help

[willfcc]

I have an ebikes.ca 2805 front hub motor that won't go.

It worked fine in the fall, when I was using SLA. I hooked up lipo for the first time, and the motor doesn't work.

The cycle analyst says I have 41.4 volts.
I opened the controller, and measured the hall signals and throttle signal. They appear fine.

Any suggestions?

Thanks.

More info...
I hooked up my SLA pack, and the motor works!

Why would it work on SLA, but not lipo?

SLA pack is at 51.5v, lipo is 41.4.

Oh crap. There it is right there...

For the SLA pack at 48v, I set the CA low volt cutoff to 44. My lipo pack is only 41.5. Resetting the CA to 38v cutoff made it work.
