The Zilla motor controller package comes complete with a standard Hairball. All Zillas require a Hairball in order to run. You can select options for your Hairball above if desired. The Zilla package also includes a three foot Cat-5 cable with ferrite to connect the Zilla and Hairball, a serial cable and adapter for connecting a laptop computer to the Hairball, a contactor snubber diode, shorting plug, two high voltage stickers and a Zilla screwdriver. The computer that you will need for setting Hairball settings must have a RS-232 serial port with a 9 pin connection. In case your computer is not appropriate or you just want a portable way to adjust settings, we sell an appropriate Palm Pilot handheld terminal in the accessories section.

· Maximum nominal input voltage range for Lead Acid batteries: 72 to 348 volts.

· Absolute maximum fully loaded input voltage range: 36 to 400 volts**

· Maximum motor current at 50°C heatsink temperature: 2000 Amps

· Maximum Battery Current at 200V: 1900 Amps

· Maximum Battery Current at 300V: 1770 Amps

· Maximum Battery Current at 400V: 1600 Amps

** At this time we are suggesting not exceeding 375 volts on the EHV models, we hope to bring that back up to 400 volts with further testing


· Simply, the most powerful controller in the industry, by far.

· Backed by over fifteen years of experience making the worlds quickest controllers, plus a factory warranty.

· Water cooling for sustained high power operation.

· 2000 motor Amps available with proper cooling.

· Multiple Microprocessors which cross check for security and safety.

· Full motor current limit control with smooth temperature cutback.

· Silent high frequency operation.

· Compact size, dimensions: 7.00" Wide, 4.63" High, 14.75" Long

· Weight 29.5 lb.


The Hairball interface is required to run the Zilla controller. It is included in the Zilla package. It enables many new features and safeties listed here:

· Control connections to the Hairball are low voltage and referenced to the vehicle 12V ground for safety.

· Controller precharge circuit is included with self resetting fuse and arc-less main contactor control.

· Uses standard 5 K ohm potentiometer for pedal input (not supplied in package).

· Available configured to run non contact Hall Effect accelerator pedal assembly instead of the 5K pot.

· Unique "accelerator to amps" transfer function for smooth starts, even in high voltage systems.

· Standard RS-232 serial port for adjusting controller parameters.

· Programmable motor voltage and current limits.

· Programmable battery voltage and current limits.

· Valet mode to allow yet another set of settings on the fly with the flip of a switch.

· Two motor speed inputs for overspeed limiting of one or two motors. (requires motor speed sensor, not included)

· Separate voltage, current and speed limit adjustment for reverse.

· Adjustable low battery voltage protection.

· Additional battery voltage indicator set point for operating a dash warning light.

· More than forty status and error codes insure easy diagnostics in case of faults.

· No serial terminal is required to read and clear status and error codes.

· Main contactor voltage drop and stuck contactor monitoring.

· Pulse output for driving a standard 4 or 6 cylinder tachometer.

· Two dash light outputs for driving a check engine light and low battery indicator.

· Overheat indicator built into dash light output.

· Inhibits driving when plugged in, also indicated on dash light. (Requires switch on AC inlet)

· Stalled rotor protection to reduce the possibility of damaged commutators. (Requires motor speed sensor, not included)

· Optionally, up to six high side contactor drivers allow arc-less control of electric reversing and series parallel switching of dual motor systems.

· Optional Autoshift automatically shifts dual motors from series to parallel and back again at the optimum time for more power and efficiency.

· Hairball code with new features can be downloaded as it is developed by means of the bootloader and flash memory, using your home computer.

· Dimensions: 3.5" Wide, 1.75" High, 10" Long


The Hairball has a few hardware options that can be configured when it is first manufactured:

· -P: The Hall Effect Pedal input option. This option enables the Hairball to use the HEPA throttle pedal which is sold separately in the Accessories section. The Hairball with the -P option installed must use a HEPA pedal for input, it can no longer be used with a normal pot box. Please see the HEPA pedal listing for important fitting information. This option is available on the base Hairball or in combination with the -A or -S.

· -A: The -A option adds six contactor drivers for controlling motor contactors. This is normally used if you plan to use contactor sets (such as the SW202a which we sell in the Contactors section) to electrically reverse the motor(s). If you are planning on switching two motors in series parallel arrangement (this is used in dual motor race cars) then you also will want this option. The -A option adds functionality to the standard model and so enables for future expansion in case you are not sure of your final configuration. This can be combined with a -P option.

· -S: The Sparrow option was made for use in Sparrows but also has other applications. This option adds two contactor drivers to the standard model for forward/reverse switching of one motor. Unlike the -A option, the Sparrow option has been configured so that it can use reversing contactors that do not have built in microswitches for sensing contact position. This is good for vehicles like the Sparrow which are configured to use the Kilovac EV200 type contactors for reversing therefore it is better to use the -A option when possible. The -S option also has default settings that are reasonable for a Sparrow. Settings can be changed after setting the defaults. This can be combined with a -P option.



A 12 month written warranty is described in the installation manual found HERE
