Parts are ordered

I got my parts ordered as well as the batteries. I ended up going with 38 Thundersky 160ah batteries for  approx. 120 volts. This will give me enough range to get to work and back if for some reason I can't charge at work. Also, my car should have pretty decent power with my controller running at 500 amps. If I got some bigger fuses, I could run up to 700 amps, but that would drain the batteries pretty quick. I ordered everything from Justin at www.evolveelectrics.com. He was very helpful and quick to respond to emails and changes in the order.

Here is a list of the parts:

DRIVE SYSTEM
Netgain Impulse 9 Motor - Double shaft- Set up for clockwise rotation for the Honda
Netgain Warp Speed Sensor - for the Tachometer and speedometer
Curtis PB-6 Potentiometer - connects to the gas peddle to tell the controller how much battery juice to feed the motor
2 Albright SW-200 Contactors - wired to the ignition to close the circuit from the batteries to the controller
Clutchless Transmission adapter plate - I decided to go clutchless - a little tougher to change gears but I think it will work out fine
BATTERY SYSTEM
Elcon PFC-2000+ Charger - Battery charger - 115VAC at about 12amps - I think about 5.5 hours to charge 40% of the pack which is more than I will use at one time.
6 feet of 6AWG Welding cable - power from the plug to the charger
30 feet of 2/0 Welding cable - running between the battery packs, motor, controller and safety devices
Various Heat shrink and Lugs - for power cable
500Amp Ammeter - This measures amps going from the batteries to the motor
60-160V Voltmeter - This measures the battery pack voltage
500Amp Shunt - this lowers the power going to the above meters so they don't blow up
40 Thundersky 160 Ah batteries and connectors - I will be running 38 and have 2 spares
SAFETY SYSTEM
VBS braking kit - This is a vacuum pump which creates the vaccum needed for the power brakes to work
IOTA DLS-55 DC to DC converter - This changes the voltage from 120Volts to 12 volts to charge the accessory battery
Ferraz 500amp 300VDC Fuse - Going over 500 amps will shut the car down - I will set my controller to limit the amps to 480amps
20amp Fast acting Fuse and holder - for 12volt accessory system
First Inertia switch - If I get in an accident, the inertia switch cuts power to the system
2 Anderson SB-350 2/0 connectors - for the battery system - manual disconnect to service the car
2 Anderson SB-50 6AWG - for the charger system - manual disconnect to service the car
12Volt 40 amp relay - for the ignition system

So, it is alot of parts, but nowhere near what a gas powered vehicle needs, and not nearly as many moving parts which is what causes failures in gas powered vehicles.

I will be eagerly anticipating receiving them and also continuing work on the DIY controller.  Depending on how long the batteries take to get here from China, I could be up and running in a couple months. This also depends on the schedule of  MECHEN the mechanical god (James) who will be helping me figure out how to put this all together and attach it to my car.

Exciting News

So I finally finished the control board section of the controller. I took it out to the garage and wired it up to a 12V car battery and just like that, the green light lit up and the yellow light was flashing just as it should. A great sense of relief  and excitement hit me. I really did not want to have to figure out what component might be faulty or I burned up, or have to order another control board and start the soldering all over again. I will also try to hook it up to my PC tomorrow and run a little diagnostic program on it to make sure the chips are working properly. Then, I will move on to the power section of the controller. I have been putting off ordering the rest of the parts for the car because I can not seem to make up my mind about the battery pack. I want to go with the lower cost of the 4 packs, but am afraid I won't get the cycle life or the power out of them that I want. The difference is about 10-30% more between the 3 larger packs, so maybe I go with one in the middle.
