These are newly hand assembled Infineon 24 FET controllers I am selling, they are new and never used. It is originally optimized to be used with midsized electric motorcycle and [color=#0000FF][b]ebike racing[/b][/color] applications. The best motor to be used are the the Crystalyte 5 series and motorcycle hub motors.
There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to TTL serial adapter and connect to the controller for tuning. (Electronics knowledge is required to unleash the potential however)
If you are going to use a 9C (Nine Continent) motor, it is recommended to reduce the current setup due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage.
One unique design is the welcome of the embedded switching power circuitry to step down the high voltage and feed the MCU (motor control unit). The static-state current switch module that draws only 22mA, which is about 1/3 current draw of the current controllers using the high power resistor. This way, the controller will run much cooler and more energy efficient.
Another unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra output lead/pin. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard that reads electrical pulses.
If you look carefully in the pictures, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.
Lastly, there is no compromise for safety. The controller is equipped with silicon and high temperature wires for flexibility and heat resistance up to 200 degree Celsius or 392 degree Fahrenheit. The phase wires to the motor are also high temperature equipped. I have also added the high power connectors so you do not have to.
This is a top of the line controller that comes with all the bells and whistles that are typical needed for the racing application including the CA connector, regen enable/disable jumper, and the USB-TTL plug for use with the programming adapter.
$15 for USB-TTL programming adapter with a push to send button and connector. Windows XP/Vista/7 32/64 bit operating system (real 32/64bit drivers).

I currently have only 10 made as of Aug 27th, 2012 since I am busy working on my other ebike projects. My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. :wink: I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on. These controllers are not generic controllers. I have every single one serialized. Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed. :lol:
