Alltrax
Connecting a Alltrax motor driver

WARNING: SHOCK DANGER

The Alltrax motor controllers do not provide isolation between the high voltage battery and the low voltage circuits.

The B- terminal is the common ground, as is the "Throttle 2" terminal.

The "Throttle 1" terminal has an internal pull up to an internal 14 V supply. When loaded with a 5 kOhm throttle pot, that voltage drops to about 3 V (full throttle) down to 0 V (stopped).

Note that the Alltrax controllers have not filtering whatsoever, so it is an exceptionally high source of noise, so you may have some difficulties with the BMS.
