Zilla

Using a Zilla motor controller with an Lithiumate BMS.

Be aware of the fact that the 'Zilla has not filtering whatsoever, so it is an exceptionally high source of noise, so you may have some significant difficulties.

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.
