Vehicle | 2000 Mazda Miata Stock weight and handling. | ||||||
Motor | Netgain Impulse 9 Series Wound DC recycled from Electron Transport WebPage | ||||||
Drivetrain | Retained clutch. Lightweight 8 lb flywheel. | ||||||
Controller | Zeva MC1000C A big improvement over the Logisystem 550 amp. Spins the tires in first. | ||||||
Batteries | 3.75 Volt, Lithium-Ion 48 Nissan Leaf modules connected 6p16s for 120 volts nominal. Actual full charge is about 133 V. Great batteries so far and far cheaper than new. Get them from a wrecked Leaf. | ||||||
System Voltage | 120 Volts | ||||||
Charger | Manzanita Micro PFC 20 BMS four MK3x8's from Manzanita Micro | ||||||
Heater | 800 watt ceramic inserted into old heater core and activated with relay connected to fog light button. Not sufficient, but it's Florida. Only needed about 1 week of the year. | ||||||
DC/DC Converter | Iota DLS 45 | ||||||
Instrumentation | Stock speedometer still works. ZEVA control panel and Tachometer in dash. | ||||||
Top Speed | 100 MPH (160 KPH) Theoretical top at 5000 RPM in 5th gear based on gear ratios and tire size. Actual top speed achieved 75 MPH. | ||||||
Acceleration | Better than stock. Can use 3rd gear to start and go to 4th above 45 mph. 2nd for really quick starts. 1st to spin the tires. | ||||||
Range | 65 Miles (104 Kilometers) Estimated. I have done 45 and had some capacity left. | ||||||
Watt Hours/Mile | 210 Wh/Mile @ 50 MPH | ||||||

Curb Weight | 2,400 Pounds (1,090 Kilograms) TBD but close to stock | ||||||
Tires | 185/60/R14 | ||||||
Conversion Time | 8 months nights and weekends | ||||||
Conversion Cost | Car $3100. Batteries $3500. All other parts were recycled from former car. Probably $6000 worth. about $13,000? Now $14,500 with new Zeva controller. Well worth it. | ||||||
Additional Features | Keeping charge cycles between 80% and 20% DOD as much as possible to extend battery life. Insulating foam added under hood and trunk to keep the batteries from heating due to the sun. Works well. | ||||||
Love it! Highly recommend the Zeva controller and the Leaf batteries. As of April 2019 charging off of solar at home, where I do 95% of my charging. |
