|Heater||120V 1500 watt ceramic heater running off 144V. Switched with 2 x 220V DC relays.|
The original 240V one was useless so I bought a 120V one from the US.

Modified to work on DC only.
Current inrush limiters have been fitted.

150km is the maximum range driving gently with no high speed.
100km is kinder to the pack & usual daily use is around 30-70km.

|Conversion Time||12 months in the planning & aquiring all the parts.|
6 months in the actual conversion. 100% done now.
|Conversion Cost||A lot of time mostly!|
Doing an electric car conversion properly & getting it right is a bit more involved than what I had envisioned.
The financial cost was spread over a year so I did not really notice it.
|Additional Features||Original air conditioning is retained & is driven by the tailshaft of motor via a custom pulley.|
Power steering is retained & the power assistance is provided by a Toyota late model MR2 EHPS unit.
A VBS pump kit supplies vacuum for the brake booster.
I did have Thomas pump but I scrapped it because it was too noisy & too slow.
Dual Kilavac contactors, dual traction pack fuses & an inertia cutoff switch for added safety.
|The conversion is totally finished.|
I drive the car every day for the usual school run & shopping.
