Vehicle	1995 Saturn SL2
Motor	Netgain Warp9 Series Wound DC
Controller	Synkromotive DC750 It's set at 500a battery, 650a motor right now.
Batteries	48 CALB/Skyenergy CALB 130ah, 3.20 Volt, Lithium-Ion all 48 cells are in the trunk. 36 in a sunk down battery rack, 12 against the back seat.
System Voltage	153 Volts
Charger	Manzanita Micro PFC30 Set up with an L6-30 plug (220v/30a), and adapters for the most common outlets. I also have a J1772 adapter box from tucsonev.com for use with public charging stations.
Heater	two 1500w elements in the dash, wired together they pull 14a at 150v for 2100w.
DC/DC Converter	Iota DLS-45
Instrumentation	Bluetooth EV Display from emotorwerks.com using my DroidX on the dashboard. I have battery amps, pack voltage, Ah remaining and Wh/mi showing on the screen. Also now have the stock tach functioning again, but it reads about 30% low...
Top Speed	70+
Acceleration	update with Synkro at 400a (750a motor): 0-40 = 8.6 seconds 0-60 = 16.4 seconds With old Logisystems set at 300a: 0-40 = 13 seconds 0-60 = 26 seconds
Range	50 Miles (80 Kilometers) to 80% DOD if driving with an intent on range. Normal driving is closer to 40 miles, and heater usage can suck the power quickly as it pulls 14a when running.
Watt Hours/Mile	320 Wh/Mile usually average between 290 - 350. Steady 55 on the freeway is around 250 Wh/mi. Stop and go in town is significantly worse.
Seating Capacity	5 adults
Curb Weight	2,760 Pounds (1,254 Kilograms) ~350 pounds heavier than stock, and much more rear heavy. Was 60/40 F/R, now 47/53 F/R.
Tires	stock size - 195/70R15
4/3/13 - upgraded to a Manzanita Micro PFC30 charger. Now I can pump in 30+ amps from 220v. I also added J1772 compatibility. 5/7/12 - re-did broken motor mounts, much more solid but still suffering from excessive driveline backlash. With the warmer weather I'm now pulling 500a from the batteries, but have the motor side limited to 500a also to reduce drivability issues related to the driveline backlash and some clutch slippage at high current/low rpms. 11/5/11 - replaced Logisystems controller with Synkromotive. Wow, what a difference. It is smooooth and easy to drive now, exactly what I was hoping for from the beginning. The Logisystems 750a controller was harsh and jerky, I needed to use the clutch to get a smooth start. The Synkro is worlds better. It's currently set up at 400 battery amps. Quick off the line (can spin the wheels in second if I have the motor current cranked up), average after that. Easily maintains 65mph on the freeway. 10/19/11 - Bought it already converted but needing work. It's been fixed and is back on the road, but is not 'done.' Are they ever?
