This is a special request edition from my previous buyers who wanted to have the added options and do not mind a few extras. This controller is plug & play and ready to program. I have added the following in addition to the original:
1. Cycle Analyst connector plug (see picture below)
2. Regenerative braking can now be enable/disable by connecting/dis-connecting a wire with male/female plugs (see picture below)
3. On the controller side, it has an external connector to the USB-TTL adapter
4. It comes with an USB-TTL adapter for this edition
5. The USB-TTL adapter features a connector that can separate between the USB-TTL module and the controller
6. The USB-TTL adapter comes with a programming activate switch

Original description from last month:
These are newly hand assembled Infineon 18 FET controllers I am selling, they are never used. It is originally optimized to be used for commute in the San Francisco hilly area with stop and go traffic. The best motor to be used are the 9C and the Crystalyte 5 series.
The controller is like a wolf in sheep's skin because it is under tuned in order to balance between power and range. 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 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 stay with 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 feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard.
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.
Below is the specification:
Model: EC-184310-LYEN EDITION
Start immediate controller
Chipset: XCKJ8B116A
Circuit board version: EB218-A-3
18 x genuine IRFB 4310 MOSFET N-CH 100V (tested up to 110V before damage) for more information about the FET, click the link below:

100V 1000uF Nichicon capacitors equipped (go to their main website in Japan here > http://www.nichicon.co.jp)
72V battery optimized (for higher or lower voltage & current such as 36V-100V, you may need to change the resistor network to avoid damage to the voltage regulator)
65A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off: 62.6v
Battery and motor phase wires gauge size: 12AWG
Dimension: 9" x 3.4" x 1.75"( 229mm x 87mm x 45mm) plus mount extensions
Total weight: 805 gram
In case you want to upgrade it later on to became methods-proof and doctorbass-proof, you may need to upgrade the FETs to 4110 to achieve higher current as well as voltage above 100V. We have a friend here Steveo who do awesome controllers upgrade for a fee.
I have only only 2 made as of April 14th, 2010 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.
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. 
[size=200]$199 USD free ground shipping in the US & Canada. For other locations, please PM or email me at LYEN@HOTMAIL.COM. I accept PayPal, cash or money order. The controllers will be shipped out from me in San Francisco, California, USA. I will provide a tracking number and ship it out as soon as I have received the fund.

If you are not satisfy with the results or if it is too much power for you, you may send it back to me within 30 days in an unmodified condition.
Update: April 1st, 2010 > I can adjust the controller for 24V, 33V, 36V, 48V, 60V, 66V, 72V, 84V, 96V and other battery settings upon request.
