I've been looking for another controller that will either go with my existing motor when it gets transplanted to a new project, or to go with my new Leaf motor once I finally get around to upgrading my current bike. Similar to the current PowerVelocity controller, I wanted it to be sine wave, decent current, and a flexible voltage range. Regen and push button cruise control options are nice-to-haves.
I spotted this last night and decided to take a chance on it and picked it up for the $95 I offered:
It looks to be something similar to the 18FET version here:

Here are some questions for anyone who knows about these Crystalite controllers. I read a couple of thread on the forum already.
It looks like the LVC is 40V, for the 13S voltage, and if everything is unconstrained in the default settings, the controller should work fine for my purpose, without having to access any program settings. The controller has a CA connector, so I may only need to run the CA cable, plus the on/off and 3-speed switch cables to the handlebars, so a fairly clean installation. Anyway, seemed like a decent deal for 72V 60A sine wave/FOC, so worth taking a chance on. If it's genuine and has the 4115 FETs, then that's even better. No cruise, and I don't like the CA auto-cruise, but I'll live.

- The voltage range of 48V-72V seem to be the nominal voltage ranges, so 13S to 20S. One part of the listing says max input voltage of 78V, which I think may be tied to the max regen voltage. My guess is it will go to the 84V of a 20S battery, but I plan to open up the controller and check the caps and fets unless someone confirms the ratings to be nominal battery voltages.
- The label says it supports regen up to 78V, and I noticed that the brake switch connector has 3 conductors. I'm wondering if the controller is capable of variable regen.
- For the thermal JST connector, I'm wondering if that's an input or output (input from thermistor in the motor, or output from one in the controller).
- Any idea where to get the software or hardware for the USB programming connector.
- Any idea about the phase amps the controller is capable of. I'd be moving from 70A battery/200A phase current, to 60A battery, but I usually only see 60A now under acceleration anyway.
