Brushed esc for tracked tank

As an introduction to ArduPilot I would like to convert a tracked vehicle with 2 9vdc brushed motors across to run with a Pixhawk.
Will this esc work? Do I need 1 or 2 of them?

Those ESCs will not work with Ardurover, because they do the skid steering mixing. This interferes with Ardurovers mixing.
You need two single ESCs.

Edit: The expanded discription says they can be configured for independent/non mixing mode. If that is true, you can use one of them to drive your two motors.

Great thanks I’ll give it a go.
