Zilla

Using a Zilla motor controller with an Lithiumate BMS.

The 'Zilla is a very high power device which does not include any filtering, making it an exceptionally high source of noise, affecting various electronic devices in the vehicle.

Even so, the Lithiumate BMS has been succesfully installed in vehicles with a 'Zilla by people skilled in the practice of working with high EMI products, and who have carefully followed the Lithiumate installation instructions.

To reduce the effect of electrical noise on the BMS, please make sure that someone with such skills is available during the installation of the motor controller and of the BMS.

Interfacing a 'Zilla motor controller and the Elithion BMS

The DCL line from the Lithiumate normally sits at 5 V; when the battery is close to empty, it starts going down.

The diode clamps the maximum voltage across the throttle pot, so, as the battery gets more and more discharged, there is less and less available range in the throttle pot, and therefore the torque is limited.

The LLIM line is normally grounded (its polarity is flipped from the default) and is the return for the Main contactor. Should the pack go empty, the LLIM line is opened, turning off the Main relay, shutting down the 'Zilla.
